Electric Pro Academy was born in downtown Indianapolis as Jefferson Electric CEO Joel Walsman coped with raging service requests and a national stage of retirement looming for master electricians. We've found that many of the available educational curriculum for electrical apprentices are too theoretical and impractical. In response, we've sought to give a clear window into typical residential electrical work to educate and entertain viewers into joining the force! We welcome your feedback and support and thank you for watching.

Why you don't replace it in the first place so that you don't have to go back and do it all over again
what wires do you put together to keep the cirquit going if i eliminate an outlet thanks
The apprentices are ready to work!
The wall paneling needed an upgrade
Nice work!
I believe this would be a code violation. Nec 110.26 can’t have the batteries below the panel if it sticks out past the panel depth. 🤷♂️ unsafe to work on the panel above while having to lean over the battery.
So cool that you owe a Tesla!
Love the EV content
A roofer I contacted refused to give references because of privacy issues!
Do you really need back round music
When is a disconnect required?
When is a disconnect required?
Do you need to run.a green wire for grounding the tub or can you use the bare copper wire that comes with the 3 conductor cable?
If Klein released a limited-time broom every year around april fools day Im convinced theyd make a ton of money
Continuous load is 3 hours or more at max load. These chargers have load management so they do not use maximum for that long. Could you argue that?
I will argue that you cannot use #6 romex for a 48 amp continuous load since you are locked into the 60 degree column and 6 in 60 is 55amps. 10kw electric heat kits are actually rated at 9.7kw because the manufactures know that 6-2 romex is running to most residential air handlers this is done so you can use 6-2 romex . If you were to venture into the 75c column using 6-2 MC or running conduit with THWN then the panel/ breaker terminals have to be rated for 75c.
You can use the next size up rule. Then you can use #6 Romex. Not everyone is comfortable with this but it’s correct
The nominal voltage here in uk is 400 or 230 to ground I didn’t even realise till today you stepped that down further. Every days a school day
I would of just bent a back to back 90
I agree. Could have bent two 90’s with offsets, used two emt connectors, and a hole strap. Instead this dude pucked parts all over and spent who knows how long making his mini lack contraption.
Can i use this Ford Charging Pro to charge my Tesla if i get an adapter?
You should stay behind the desk and use big words
why do you have gloves on sir?
An electrical technician is a busy person of great demand.
Put the recip down and get you a multi tool lol
Love your stuff dude. Got a power wall 3 and a span panel in the garage!
75kva. In Germany, that's nearly one and a half household connections. But we don't need one transformer per house.
digging ruined me
how is smaller gauge wire feeding a 480 step down to 208 transformer and larger gauge wire on the secondary for the lower voltage?
He just explained it lol The higher voltage can carry the same amount of power on smaller wires, so when the voltage is reduced, the wire size has to increase.
You could use an LB thats listed for EMT, that would make it a better install. You’re compromising the grounding path of that conduit system. The threads on an EMT connector aren’t tapered, which is why EMT connectors are always set screw or compression with that split ring which crushes to form a good bond.
Nice catch
Here is the question HOW is the mini getting supported???
How does that mini attach to the EMT?
Cool stuff man! As a cook I’m fascinated by our equipment; The combo oven(steamer, smoker and convection oven) runs on 480v/20amp And the steam table has a thicker gauge, going into 208y box like this, with a conduit going to the ceiling. Thanks for the inside view.
Also another question. Why emt and not pvc? To the guy saying it was in the way of the switch. im pretty sure we can all tell you ran the emt with the LBs around the light switch so it would accessible. We have to do what we have to do sometimes.
Yeah I think I’m going to start putting my work on KZread. Been thinking about it. I’ve been in the trade 2 decades. Not a bad job.
That paneling is so 1965..the pipe is blocking the switch..not good
What’s going on with that big residential build series?
We’ve missed you!
The only thing I don’t like is wire nuts in the panel. But I certainly understand that sometimes that needs to be done. Sadly, new wire runs for a couple being 5” short, are typically out of the budget 😂
Power is VA: Step down transformer. VA stays the same but current and voltages changes. VA (voltage and current) change values proportionally.
Why are all your gloves ripped? I’ve never seen you with gloves that are not ripped.
Weather head
Joel, as a builder as long that stud isn't apart of the load barring structural wall? You should be alright.
Kohler generates cleaner power…plenty of tests online comparing all the different brands.
Ampacity of the conductors with other factors like VD and ambient temps will dictate conductor size which will then dictate conduit size. If it was only a voltage difference then you would see same size conductors and same size conduit on primary and secondary.
No, because the voltage difference changes the number of amps carried by the wires, thus the wire size has to change to carry the higher amps on the lower voltage.
My guy Joel has taught me so much Thanks Joel!!!
Not bad information. But the real reason for higher voltage is because you can get more power down the same 3 wires at a lower amperage. Amps dictate the wire gauge and you can reduce amps by increasing voltage
Which is because you get lower losses at higher voltage, so you can run smaller wires for the same amount of losses.
@@ke6gwf incorrect. Losses are the same. Laws of thermodynamics don't change when the voltage changes. What you could be trying to express is, that you need to have a greater differential to maintain minimum voltage requirements between transmission and distribution lines. For example. You cant input 12000volts and get 12000volts out. But what you can do is transmit 12000volts out to a transformers primary coil and step it down to 480v 3 phase or 240v single phase with a decent degree of accuracy on the secondary coil. Because we came in at such a high transmission voltage, we had plenty of voltage to transform even with power line losses to achieve correct power at point of use even when the grid is being taxed. Long story short. Power loss over distance doesn't decrease with higher voltage, but with higher voltage you have more volts to spare
@@One_More_Summer_Garagenope, you are missing a basic understanding of electrical transmission. Losses come about from amps, the higher the amps, the more energy is lost as heat, so if you can decrease the amperage on a wire, you reduce the amount of energy lost as heat. You can reduce the amount lost as heat by two ways, either increase the size of the conductor to reduce the proportional amp load, or increase the voltage and get the same amount of total energy across the same wire, but at lower amperage. For instance, high voltage fuses on big transmission lines may only be a couple hundred amps, the same as the main breaker for your house, but they are powering an entire city because the voltage is much higher. So by increasing the voltage, you can reduce the amperage on the wire, thus reducing transmission losses. If you compare UK household electrical systems with US systems, you can see this, because they may be running on a very thin wire by our standards, and low amperage breakers, but running higher current appliances than we can run on 20 amps and 12 gauge wire, because they are running 220v and we only are running them on 110v, so we have to have wires and breakers twice as large for the same amount of power output.
@@ke6gwf respectfully, you are misunderstanding part of what I said. You're second comment isn't wrong. But what I was trying to point out is, just because we increase voltage, doesn't mean we get a more efficient transmission of energy. It also doesn't reduce heat. Voltage x amperage is wattage. This is why engineers don't like using volts and amps, because this conversation becomes messy. Representing energy in kw or kva tends to tell a better story. Line transmission losses are part of the game, there's a lot of factors at play but the only way to truely reduce heat losses is to plan the grid accordingly and determine inductive and capacitance loads during peak usages to maintain a stable power factor.
One last tid bit I should of mentioned. Wire strand and material play a huge factor into it. The skin effect is real and solid core wire isnt as efficient
Yeah what about the crazy expensive price. To to to expensive
Nice... Frankly this should be the standard.
I like the well-used maxiflex... Things ain't cheap!
The biggest flaw with this unit is that when you are using it, you are not able to use shore power to charge the unit while using it. The only way to charge it is with solar while using it. There is no AC pass through. So if you have a grid power outage, and you run out of stored battery capacity, you can't hook up your generator to charge the F3800 as the 240 output will turn off. The only way is solar. For this reason, I won't buy it until they fix this.
The power is not the same. It is inversely proportional. 480V @200 amps runs through the transformer comes out at lets say 240V @400 amps,(with in reason, there are some losses due to heat and other variables). As the voltage decreases the current increases and vice versa
480Vx240A=96kVA 240Vx400A=96kVA But the power is not the same. 😂 What do you think power is?
@@tekpatlizkalotekatl530 I think @alanweaver3017 mistaken power for Amps instead for Watts. P.S; V Voltage = Volts I Current = Amps P Power = Watts R Resistance = Ohms
Taking so much longer to understand electric then plumbing.
