If you plug a power bar into itself you actually get infinite power.

For those who don't feel like counting to 15, you can grab a Kill-A-Watt meter which will tell you exactly how many amps and watts a plug in an outlet is taking. Very useful for determining how close you are to overloading! (This is not endorsed by any company, I have a few and they're great.)

@Xyspade

​@@cliffmathewYou would need to know how many outlets are on the circuit and use the device to measure the current being drawn from each one. Easiest way to find how many outlets on the circuit is to flip the breaker off and check how many outlets lose power.

Also I would also give a notice. Over time contact between chinese and even non chinese plugs/sockets tend to oxidize due to thermal cycling, moisture, also dust adds its toll. So it may start heating even if you are at 11/12/13/14A of your total 15A maximum. Also, if contact between socket and plug gets overloaded for some time, oxides and burns start to develop between contacts and that encourages even more heating. So I would recommend reaching 50-80% of the load maximum and recycling the plugs into sockets, also taking a look at the state of conductors and cleaning if neccessary. When unplugged/replugged, the conductors scratch off the oxides/dust and thus the contact improves.

3:57 You need to take the power factor into consideration. Basically it is about 0.5 on such equipment so double the figure. 4:43 It is output 1 A at 9 V. The input is 15 W at 120 V which gives 0.125 A but lets double that for the power factor so we get 0.25 A. A circuit breaker does not trip immediately if the overload is not large. Also if there is poor contact in the plug it can cause heat. The more you chain the more change there is for poor contact. Here extension cords are for 16 A. I have a 10 A circuit breaker.

The same mistake you noticed with the speaker adapter you made with the modem.

That's 0.043 amps from the mains, but given you have some losses in the adapter, lets say it draws 0.05 amps.

Thank you. I have cords, and strips plugged in everywhere throughout my woodshop. This was a big wakeup call for me.

It's quite clear to me what happened. Electrical conductors get warm when they are pushed near their rated limit (doesn't have to be over), the first place to get warm will be the weakest point, such as a connection like a plug. As a conductor gets warm resistance increases, as resistance increases it generates more heat, and it can turn into a runaway effect until it starts a fire. Your circuit did not exceed 15 amps, which is why the breaker did not trip. The problem was the cheap Chinese power bars, despite saying 15 amps they are not designed to handled that kind of load. If you've ever used Chinese batteries that say something like "6000mah" but actually are more like 800mah, you'll be aware they are not shy about overstating the capacities of their products.

It's all about load. Running a bunch of power powered devises is fine, just don't hook up anything that draws a lot of power such as a space heater.

Common sense says no more then 1 power strip at a time just because of the fact you can plug a lot of things in already. Most power strip packages they tell you not to plug multiple strips into each other. If you need a second one, use both wall plugs. These cheap power strips are a joke especially Monster branded ones, very thin copper strips running along the inside and everything is molded, which means plugs can get loose. All of my strips are metal with actual outlets. You can get them from some electronic stores and most hardware stores. Way better construction. The reason why the breaker didn't trip on the power strip nor the breaker box was because there wasn't a physical short, just a connection heating up.

I'm using both wall sockets already. My problem is the house I live in has a grand total of 10 power sockets total. the bedroom has just two. My computer setup alone requires 3 plugs all to itself. I am faced with 12 things plugged in at once right now in a location that only has 2 accessible wall sockets, and that's with half the stuff I keep around my desk not actually plugged in at all. To top it off one of the power strips I use has UK plug sockets, because I have several UK devices. That's not otherwise a problem, because the voltages are the same, but the power strip is the only way I can reasonably plug those in to anything... If these properties actually had a decent number of power sockets for modern conditions, this absurd setup wouldn't be quite as necessary. But as it is... In any event I try to keep stacked anything to an absolute bare minimum. The two standard strips are plugged into a wall socket each. The UK strip is plugged into one of the other strips. (I'd give it it's own wall socket if I could. In fact I did, when this whole setup was in a different room, but I'm simply out of options...)

Your math is flawed...lets use the the speakers as an example. Speakers DC adapter said it has an output voltage of 9 VDC and is capable of supplying 1A of current which give you a maximum output of 9 watts o f power (I know it saw 15W but I just did the math for you). 9 Watts / 120 VAC = 0.075A Max Draw on 120V mains. Basically stating that the speakers won't draw more than 0.08A at max volume....not even 1/10 of an amp from the wall. If it could draw 1A at 120 volts that means it would use 120 Watts...which is unrealistic.

Power consumption is not the same as power that goes into producing sound in speakers. Much of the power is consumed by the amplifier. And power consumption ratings, are probably more of a "maximum under reasonable conditions" rating, and not the "average" or typical usage.

It overheated because the resistence of the connection was high (the plug connected to the other power bar), that resistence did two thing, ONE it avoided the ampers (current) to go nominal 12.5A, TWO it generated heat and fire, that is the reason protections didn't trip. Was a loose connection?, not necesarily, if you study the internal shape of the females contacts, it is just a tiny part which really get in contact with the male counterpart, the parts are not perfectly parallel frictioning, notmally is a tiny part which press against the male plug. That minimal surface normally can't conduct 12.5A.... , when the power bar say in the label it is 15A, it don't reffers to just ONE female plug, female counterparts are not designed that way, but the label reffer that the sum of all females will do up to 15A, and the protection is normally 15A sustained during X ammount of period, it is NOT just past 15A barrier and PUUUFFF (instantly).

That doesn't really make sense, because it means you could overload a power strip far too easily in general. Consider I have 6 socket power strip rated for 240 volts 10 amps. OK, so if I plug in 6 devices that use 400 watts each, that's the power limit. But so is one device that uses 1500 watts, and one that uses 800 And if you don't think something can use those kinds of wattages, a typical portable fan heater is anything from 1500-2000 watts. My Desktop PC has a 650 watt power supply. And that's the OUTPUT power rating, and when heavily loaded efficiency may be as little as 80%, meaning it draws closer 780 watts. Meanwhile, it's fully possible to buy 1250 watt power supplies for computers, and while those tend to be much more efficient... It still means you're pulling more than half the total power the entire strip is rated for through a single plug. For that matter, the power strip has pretty much the exact same rating as the wall socket. If you overload the power strip as a whole you're also overloading the household circuit... So there are things like resistance and inductance and some other complex issues, and in general plugging a power strip into a second power strip isn't the best idea ever. But if you're careful it's perfectly safe. I've seen professional theatre crews plug a whole heap of equipment into several power strips leading into another power strip this way, which was then plugged into a rather long extension cord... That worked perfectly fine. (admittedly the extension cord was a 20 amp rated chord, which means something like 4.8 kilowatts, but nonetheless it was quite a mess of wires and adapters and other things...)

here in argentina is outlets at wall for 10A and 20A, if a power bar must meet it, it can be 10A or 20A in the main plug, now, now, except for industrial type, to see power bars where each individual plug is capable of that, overall thinking the POWER BAR concept is for dividing power in several female plugs, has no-sense for making each individual female plug capable of the full input Amps. Other way I would be a power extension cord, not a power bar. But, any way, this burn, your video case, is not about you did those Amps, it was just heat from a loose conection or DIRT in the contacts, that did't the required resistence for allowed heat to be developed, so, it is normal that none protection shut it down.

Thanks for the info. Might come in handy one day!

Breakers sometimes have problems with "slow blow" events, where the operation is overloaded, but everything else is within limits. Some devices also sont always draw power and allow tripping mechanisms to "reset" before the point of activation. It can be as simple as that it wasn't a true fire, but instead, an overloaded outlet connection between the affected strips. This is why price matters

Red things on power bars ARE NOT BREAKERS, they are just switches that humans can use if needed, only breakers you have there are the ones in basement. Meltdown could happen from two factors: 1st the wall plug could've been connected to a higher amperage breaker by accident, so the meltdown occurred (it would happen first on contacts between wires); 2nd it could have been a loose connection.

Moral of the story anyone: Plug as many surge protectors into surge protectors with things plugged into those as you want, just make darn sure NOT to exceed 15 amps. If those circuit breakers were not flipping when you drew a lot more, there's something wrong with it obviously, and I won't be surprised if there is considering it was from 1971, right in the middle of the time contractors were using aluminum wiring, which is extremely unsafe. If you need to be worried about anything at all it is that wiring in your house, that will go up in flames WAY before the copper stuff in the surge protectors will.

we do this on a large scale on LAN parties. we do however go thru EVERYTHING and plan how we spread it out. Here we use 10-16A 230V systems and fuses and we use 16A rated stuff AND spread it out as best as possible. we try to allocate 8A to a 16A circuit. .

This power bar is a classic case of a poor connection. Happens when the plug doesn't make a full connection. Ive seen this on CH breakers too - in particular the BR style. 14 gauge can handle 18A without a problem. The 15 A is a rating given also to compensate for high ambient air temps which changes how many amps rather conductor can carry and for how long before the insulation is compromised. The power bar problem above is avoided when an AFCI breaker is used.

It all depends on the draw through each powerbar. If you're only drawing low power, it will make no difference and hurt nothing. I agree that is a big 'if' however for someone who doesn't know what they're doing.

People just need to understand that a chain of power-strips has the same maximum amp capacity as a single power strip. You don't gain extra capacity by chaining them because every strip in the chain must bear the full load of everything that's plugged in.

It's quite simple: If you plug low-power drawing items into a power strip that's coming off of another power strip, you should be just fine. However, under NO circumstances should an extremely high wattage item (like a space heater) be plugged into ANY kind of extension, be it a power strip or extension cord. If anything, it should be the only thing plugged into that outlet. Same goes for air conditioners. Plugging a computer or laptop charger into the primary strip (the one plugged into the wall) and then using a second strip for something like an lame with a CFL or LED bulb, maybe a phone charger... You'll be fine. I have a dual strip setup at my house but I only use the 2nd strip to power a small LCD monitor, my computer speakers (about 5A), and an LED lamp.

Would each outlet, in a duplex, split the 15A (having 7 A load on one outlet and 7 A load on the other) if that makes any sense? So it would trip the breaker if you tried to put a 15 amp load on both outlets of a duplex? 2.

So a 10 A load and a 6 A load in the same duplex trips the breaker, or 12 A + 6.5 A, or 17 A + 15 A etc. 2 3 duplexes still LIKELY to have a total of 15 A, depending on actual number of wires running to breaker panel. There is no 45A breaker or circuit for residential bedroom outlets. Makes sense?

Yes that makes more sense to me. But just one more question, sorry. So, depending on how my bedroom was wired, which of these would be correct for a single bedroom? : A: 3 duplexes on their own 15 A switch (total of 45 A) or B: 3 duplexes on the same switch (each duplex handling 4 A load) or C: depends on the way the room and duplexes were wired I understand now the 1st part about fixed split on one duplex, I was just confused on how the power is routed to the room and between all three duplexes. *edit: I should look at the breaker panel, which I haven't done yet. lol*

No worries, mate. This works like water in trees gets divided to branches, twigs, shoots, leaves. The panel is anywhere between 200 A or 125 A, depending on year of manufacture and then current code. That`s the total Amps you have. The range / cooker is on a 40 A breaker, the washer / dryer is on a 30 A breaker, so if all the elements are on max setting and both appliances run, that leaves you between 55 A - 130 A for everything else plugged into outlets and all the lights. You have maybe 10 pcs. of 15 A circuits. You can not have a load of 15 A on all 10 of them at the same time. That would require 150 A, but you only have between 55 A - 130 A. Say the 3 duplex outlets in the bedroom are on a single 15 A circuit. In any combination of those 6 outlets, the 15 A can not be exceeded. Correct answer is C.

15A is the rating of the circuit. You can't use a 40a breaker on 14 gauge wire because that would over load the wiring. A rule to follow (one I learned in university) the circuit rating is determined by the lowest rated piece in the circuit. You can have a 20 plug but if the wire is rated at 15 a it's a 15 a circuit. :) The max number of outlets on a 15a circuit by code is 12 devices or 12 outlets. Or 12 lights. Or 12 anything equaling 1a each. When I design the electrical layout for a room I actually only put 8 outlets (or devices). This keeps the loads smaller for the most part and prolongs the life of the wires insulation. It also allows future additions without compromising on the electrical code.

They are safe up until a certain point, being mindful of the amount of current you're drawing will be a life saver.

All depends where you're at. Here stateside we are anywhere from 110-120 for most residential applications with some 220-240 volt plugs for larger appliances requiring special plugs. Think large residential electric dryers and range/ovens. So for our applications daisy-chaining power strips can act as extra outlets, or in the case of my college dorm an extension cord since those were banned from the dorms. In the UK and most other places that side of the Atlantic I believe use 220 for all applications. At 220 volts you are likely to sooner exceed the limitations of the single power strip. I am a firm believer in only buying products from reputable brands when it comes to anything handling electricity, especially with higher requirements. I believe what may have been the issue is that some power strips have an 'always on' outlet that could have caused a problem, or could have just been old/faulty where there was enough draw to cause the heat and melt. Too many factors for it to really say for sure based off this video alone. But typically I would agree daisy-chaining multiple power strips isn't a best practice for wide application across an entire home or business and is begging for a fire.

Ryan Slemmer the Heat generated really only depends on the current flowing through the socket and it's resistance (P=R*I^2). With the same load the current is lower on a 220V system and I theory you're less likely to start a fire. But it really depends on if the power strip is reasonable good if it will hold the bold promise molded into it's casing

Who the heck plugs a heater into a surge protector in the first place... Air Conditioner, Refrigerator, Portable Heater, Deep Freezer, All of these things draw massive amounts of wattage, and should always be plugged directly into a wall outlet. A surge protector can not handle those levels of wattage very well, which is obvious why the fire started in the first place.

I made the biggest mistake during college by plugging a heater into an electrical cord instead of an outlet and the power on the side of the room it was plugged into went out and I had to get my RA to flip the breaker switch. 5 times in the first 2 months of school. I’m grateful a fire never started but I did get fined when a separate RA reported me. Be safe with ur heaters!

For 5 years I had a power plug connect to my PC, but that same power plug extended to my TV and retro game consoles (2) and VCR. The TV was a CRT. Am I lucky or is there something that I missed concerning European electricity?

This was very helpful, thanks

So either get a longer extension cord or a longer power bank cord

You also need to include the margin of error for the electronics and also that the splitters themselves also draw a slight load individually.

thanks for the info

Did you figure it out?

I have a question, my appliances show both an input and output current. In this case do I sum up the input or output currents of all my appliances to make sure I am not exceeding the 15A limit? Thanks!

What would happen if you did that and you turn the one that is attached to the main power source off with the other ones catch on fire or something since it says there’s still electricity but there’s not and it cuts off all of a sudden

great video, very clear explanation and kinda funny.

You learn something new every day...

what if you use extension cords, and draw small amounts of power?

Amps Didn't know that was something i had to be aware about Thanks man

If I have 1000w running through a 900 joule 15A power strip is it safe? Sorry but I don’t know anything about electrical things

I used one power bar as a source that went to another two bars, powered a computer with the monitor and my studio monitors. Never had a problem (at least for the 2 years I used that config), probably because there wasn't too much current going through at once.

Thank you!

But could you plug one into another, then that one into the one that was just plugged in, then plug one of them in a power bank to make another power bank?

wonder if I should divide watts by 115V or 120V?
