Not a chance in hell that a 20 year old with limited experience will pass that test IMO.

Did you look at the links I posted?

I am not trying to discourage you from an electrical career, but rather prepare for what it is really like.

It is far more complex than most people realize.

Grounding Questions


I appreciate you trying to show me it is complicated and difficult but I do already understand that. I am nottaking the test anytime soon and I'm going to do several months of studying and I did take a look at your links I know there is valuable info there but I had to come into work so I wasn't able to look at it all. I just really want to understand why you use 3 or 4 wire
Cables between meter and main panel and where to properly ground these boxes. I know there is much more than that to it but I want to understand general idea of it and progress on my own that way. I have scowered
The net trying to find the exact info I needed but couldn't find it
So I posted here.

So the neutral current only has one path back to its source.

Grounding Questions


would anyone happen to have a picture that shows inside a meter the connection from the service cables changing it to 4 wires? i just get confused as to where i hook the 4th wire if you get what im saying. some panels dont have lugs in them for a 4th wire so thats throwing me. i know from the meter with 4 wires to the main panel you hook the 2 hots in the appropriate lugs the neutral in the middle of those and the bare ground to the ug for the ground bar. just confused about the other end.

Electricity in the hands of fools can be such fun to watch. But the fools tend not to live so long.

In general, the only time there are four wires from the meter to the panel is when there is a three phase service.

Op is out of his league and won't admit it. I am thinking " bull puckey" on his experience.

To the OP, if I am wrong I will apoligize, but these are 1st year apprentice or DIY questions. Do not try and BS us. Sparkies can tell.

Fourth wire? Think of it this way for residential wiring; you don't have four wires until after the service disconnect.
