Interesting maintenance topic. I had a circuit with a pet water fall drinking fountain. It used a small electric pump that burned out. I ran through two more “must be defective pumps” before calling an electrician. Couldn’t think how it could be the circuit as a coffee maker on the same outlet was fine. Electrician traced problem to a lose breaker wire which wasn’t properly tightened. In any case he put a meter on it an showed me that the lose connection was causing voltage fluctuations. Thanks for your video.

I had the doorbell transformer wire fall out of its circuit breaker last week. I pulled the breaker out to ensure the 16 gauge wire was actually entering the toothed wire jaws in the breaker. Torque on the no-wire breaker was very tight to loosen it and I retorqued by hand. It was obviously not inside the wire jaws previously. I am not sure how the “tighten then pull on the wire to see if it comes out” method didn’t work.

Thanks for the great video. Except in recent videos, I have never seen an electrician use a torque screw driver on circuit breaker screws to tighten down the wiring for good contact. That is roughly 70 years of watching construction workers! For the safety of my wife, our children and me, and our house $200 is cheap. Thanks again.

Love this video ,as a building inspector,our city requires torque test on panel inspections, I also refer your videos to contractors that ask “why they have to torque when no other city requires it”👍 good job ben

A lot cheaper and you get the same affects.

In my University we have make a test, how high the force of a connection is at the beginning and how the force is decreasing with time. First we increased the force of the screw so high, that the cooper string which is between goes in a condition of material flow, so that he is not round any more and the force is pressing the surface on the contact-area, so that they are flat to each other. The force decrease in the first seconds very fast and within the next days slowly, till the material is not any more in this flow-mode. This means that the copper-wire does not change his shape any more. But this means that you can build up a force of 36 inch pounds (we use Newton Meter , Nm) and after a while the force has reduced to maybe 32 Inch pounds. This means that you can go to the same Panel and increase the force to 36 Inch Pounds again, but this will make the cable more flat. A while this will be okay, but some day you have to cut of this peace of cooper and use a new section of the cooper-wire which is unused. An other interesting fact is the way how the force if wires will be reduced. If the wires heat of because of a high current, then the diameter want to increase (material expansion because of heat), then the material comes into the flow-mode and the contact force will be reduced so that the material comes out of the flow-mode. But if the current in the wire is reduced, the heat will decrease and the diameter of the cable is shrinking (a tiny bit), but because of this the force is lower that at the beginning. Now we increase the current over the wire again, but now the connection is not so tight any more and this will increase the contact resistance and this leads to more heat. 😕 More hat means more material expansion and again a decrease of the pressure-force to the contact. This goes on and on ... and is the reason for for cable fire in the meter box, flush-mounted sockets and everywhere where contacts are. The best solution in my opinion is to use circuit breaker with spring contacts, there the force is always the same and the maintenance effort is reduced. You do not use special tools to create a good connection. Some of he "Hager" circuit breaker have it and there it is called "QuickConnect". I think in the USA they will have something similar.

@@whotobelieve3612 - No. Imagine you have maybe 3 sheets of metal and you connect them with with screws. If you heat up this metal, then all 3 sheets will expand and increase the force on the screw, so that the screw will expand too. The force will go to unlimited, because expanding metal .. is not easy to stop. If you cool this down now, then the 3 plates will be loose a bit and do not connect to each other so good any more. If you use a spring between one side and the nut, then this force will be nearly constant. Even if the 1 inch thick sheet of metal will expand 0.01 inch, then the spring (maybe 0,1 inch in length) is able to reduce the increasing force to only 110% of the initial force of the spring. If you do not use a spring, then the additional 0.01 inch will increase the force on the nut to an insane value. The screw or the piece of copper that is in between has only the choice to deform.

I don't know if this was mentioned, but if you are working on an older house that has Aluminum wiring, this is EXTRA IMPORTANT: they have a much greater chance (in my experiance) of loosening over time, due to the dissimilar materials (Alum wire/ brass terminal screws) heating/ cooling at different rates. I've always just made sure they were "tight" by feel, but I'm gonna grab my gunsmithing (Wheeler) tourqe screwdriver and check some screws on a panel I recently replaced in my garage :)

I owned a house that was built by the previous owner. I think he did his own electric work. I got voltage rises in my kitchen when a toaster was turned on. I traced it back to the sub-panel neutral which the installer had cut too short. It was pulled tight and had a 90 degree bend entering the lug. It also was not tight enough. Over time the aluminum wire had heated, oxidized, and became even looser. I was able to fix this, before I fried any 120 volt appliances. A loose neutral is a serious problem, so if the power company suspects it is in their connection to your house they immediately send a line man to correct it.

I recall when I was very young and learned about electricity in high school: getting brave and opening our families panel to look around, I checked the screws out of nothing else to do. They were loosish like your first example. These two videos prove a little tinkering can be good.

I saw another similar video about this torque screw driver. They have some good advice about backing out all the screws first than going back using the torque screw driver to properly reach the spec torque settings. Sometimes people over tighten and I know that can cause issues as well down the line.

Benjamin, great video except you just got started. Our company used to do scanning of electrical components as part of preventative maintenance as part of our business. When scanning panels, we would find hot connections. 99% of the hot connections were the neutral connection, not the breaker or hot connection. Not sure why but that is reality.

Thanks for the video - I have a similar torque wrench for mounting scopes on rifles, now I think I should use it this weekend to check my main panel!

because of these videos with that screwdriver I ordered mine yesterday. I cant wait to put a video out on my channel doing the exact same thing in my panel at the house. The torque screwdriver was expensive but in our line of work 200 isnt nothing when you factor in something bad happening to someone's house. Those loose connections will get you for sure ... Great video brother.

I bought this kit after seeing your video. Part of my profession is installing lighting control systems. This has been a great addition to the tool box.

Your muscle straining does a good job of showing that 36inch/pounds is pretty darn tight with a standard screwdriver, obviously much easier to hit with a wrench due to leverage. All the pros and DIYers that tighten the screw to 'tight' and check it by pulling on the wire are fooling themselves. You really need to put some muscle into getting the right torque.

@BenjaminSahlstrom

2 жыл бұрын

I was surprised by it as well. I want to test it against another torque wrench to make sure it's accurate. I don't really doubt Wiha's quality though so I'm sure it's correct but it did feel really tight.

That is an interesting conflict. They're supposed to be torqued once, not twice. Yet many of the torqued 'once' connections I've encountered allow you to pull the wire out of the connection with a simple tug. The torque thing definitely has some flaws...especially with stranded wires. Just IMO.

Also check the neutral wire and earth wire. And in the sokets too. Another tip. Place the wire loop around the screws in a clockwise direction if possible, so the wire turns in and not out when tightened. The WIHA screwdriver is insulated up to 1000 volts.

Be nice if there was a 1/4 in square hole in the end of the handle so you could use a ratchet to assist in getting it torqued down. Does look like a lot of force just for the spec you showed in the video. Sure it takes its toll after a while. Really enjoy the channel. Thanks for taking the time to put together all these videos.

For sure. I watched the lights get bright and the picture on the T.V get really big. Just at random. Found loose neutral in the panel. Good post.

How about the main lugs, were they loose also?

I use the turn until it strips method and hope for the best.

Yeah, me too previously. I try to stop right before it cams out but somehow thats a pretty hard to do consistently!

Thing is: You cannot 'verify" torque by rechecking. Wires collapse under [mechanical pressure] load with screw-type tightening devices. Hence the argument for 'spring-type' devices. I still like screws over springs but realize that screws are fixed-position and springs maintain mechanical load. Fun stuff.

It's the same with torque wrenches you want to set it at the minimum after your done as you don't want prolonged 'pressure' on the internals of the tool, as it will/can go out of calibration range.

I had a problem years ago with loose connections for my dryer receptacle. I do wish I had a torque screwdriver, however an electrician taught me a trick and I would be curious if this works. Tighten it down until it stops, then back it off a little bit, then you can tighten it a little further.

Proper torque is really important. I had a hot tub circuit board fry with one of the leads melting in its connector.... must have loosened over time.

You can buy a petty nice inch pound torque wrench with fittings that are used in bicycles shops for under $80 dollars. It would would take some of the grunt out of wiring a box. I’m a automotive mechanic that just sayin. Oh! I almost forgot you helped a bunch when I was installing a generator connector box, running conduit, installing the safety lock out slide switch thingy, moving breakers, grounding every piece of metal, and running 6 & 8 AWG wires. When I was done I Ohm’ed every wire at least three times looking for shorts before test running the install. I don’t like working around big time utility or big generator voltage. But I did get the certified Electrician down the street come and inspect it all. I was very proud of my work but he just said it was OK!😦

Thanks for bringing up this subject. Don’t forget that copper is fairly ductile so it will deform a little over time rendering the connections looser than when they were installed. If the panel is located where there is a wide swing in temperature that also causes the connections to become looser over time. Additionally, some breaker circuits that are heavily loaded may also be subjected to the conductor heating up a bit. All of these factors result in the connections loosening up over time. Also, it is not just the breakers that require correct torque, but this also applies to the ground and neutral bus bars, in feed connections, etc. What I don’t know is how often that the connections in any given panel or disconnect switch should be revisited for correct torque. Anyone know this?

We've all probably over tightened something at one point or another. It's a horrible feeling to strip something out but can give us good data as far as feel goes. I personally am an over torquer so I tighten things to the point just under where I think I'm going to break it. For people with the opposite problem, perhaps give it another twist and call it good. I think we would all (nearly) would love to have something that gave us that type of consistency but the reality is $200 for something that doesn't come with bits is far from idea and why we don't all have them. Don't get me wrong I would not trust a $10 one but there has to be some mid meeting point. I must say the click is super satisfying. I think it would become more of a must have in my tool bag if that was my main function but since I only deal with electrical when necessary I'll have to live vicariously through your examples and clicks, LOL. Cool tool, cool video. :)

It looks pretty scary to me even though they were under torqued they seem to be very firm beyond just loose. Always get a little nervous when you do inch pound torques! Great video very cool torque wrench

Should you check the common and ground as well. Does it have a spec and what would it be?

Soft joints can and do relax by as much as 50%. Proper initial torque takes this Into account and torque checking also needs to take this into account.

Benjamin, Thanks for another quality video! Short comment: Don't forget the Neutrals. I see this loose connection problem a lot. So, the Neutral bus connections should also be checked when performing this procedure. The Neutral conductor connection is often overlooked or misinterpreted as a less important current carrying conductor. But, with the increased influx of electronics and switching power supplies, the potential for harmonics in the local electrical system is often increased and so, increases the need for maintaining the integrity of the Neutral conductors and connections. The "Unseen load" created by Harmonics in a system can be problematic and in some cases calls for up sizing the Neutrals. Thanks again!

You got some 2 hot wires going into some of those breakers. That might be why they aren’t torqued down properly, unless those breakers are listed for 2 conductors.

I found some loose breakers in my apartment electrical panel. Plan on making a call.

For bolt on style breakers does the torque spec apply to the wire connection and the bus bar bolt on connection?

Good vid and good demo ... Thx for sharing ...

Great idea to check connections 👍

I get the concept but for residential panels let's say there are, what, between 20 and 40 or so connections whereas, yikes, 10x or more connections throughout all the circuits? I respect the German-engineered Wiha tool but until everyone starts installing Wago nuts or similar in all their j-boxes should there also be a $200 torque thingy for wire nuts? If safety is paramount why stop with the load panel? I'm not being completely sarcastic because, seriously, I recently found a partially melted wire nut in a J-box that I think it was due to a loose connection.

Very good lesson for me.

This is not a proper method of verifying proper torque was applied when the connection was originally assembled.

It would seem like there is not such thing as "over torqued"? Since the screwdriver will break loose, it is not capable of telling if a screw was torqued too much (risk of breaking internal threads or holders). Any thoughts on this? Great video...

You only showed checking the torque of the HOT leads. You also need to check the NEUTRALS! They carry the same amount of current. You can find the torque spec for the neutral buss screws on the panel label (or contact manufacturer). If the buss has different size screws, they probably have different specs. I bet if you do check them, you'll find just as many (or more) loose neutral leads.

Curious what as some of the causes for random light flickering in a house? Say like in a room the all the circuit has a quick flicker. Lights and outlets.

The proper way to use any torque wrench or screwdriver is to tighten slowly until it clicks and then stop turning. If you are tightening quickly, or turning past the point where it first clicks, you can get the screw / nut to tighten more than the torque you set. So if you keep turning past the click, it will keep clicking, and may over-tighten a little bit, but eventually the screw won’t tighten anymore
