I received a call for a home without power. I have something odd taking place and don't know of any solutions here and need some suggestions on this one. I will give you facts then some pictures.

Information:
125A Breaker using 3/0 Aluminum when 2/0 is the requirement. Aluminum has 0 give as they left no extra wiring at all and they gave the wire a hair cut to fit into the breaker causing it to arc in the terminals of the breaker. It melted some of the undersides of it. For testing, I replaced the breaker as I wasn't getting voltage from the terminal to ground indicating bad breaker. After testing I noticed 0 volts when testing across L1 and L2. Here are the photos and tell me what you think.

It's definitely on their side. When you open the breaker you remove almost all resistance. That is why you at least get 120v . When you close the breaker your resistance goes up voltage goes down . And may have lost 1 phase.

I would recommend redo on that service! Looks hazardous! Where is the ground electrode conductor. And is the neutral and ground separate at breaker panel. Only looks like 3 wires going out of back to somewhere.

Son of a gun!! I thought I didn't hit the submit button because I was writing it but didn't think I hit the sent button and I got on a phone call. Since I didn't hit the notifications check box I had no idea people were responding to it, I now see a bunch of responses. I'm going to that thread now, thank you.
