Does NEC allow two or more wires in the same neutral or ground buss hole? Or do I have to put one wire per hole? Thanks.

Thanks for the clarification and responses.

NEC 250.50 says a service panel should be grounded to a metal/copper water pipe. In my case, PEX was installed between the water meter and house. Four inches of copper pipe is exposed on both sides of the foundation wall. PEX is used in the house. Am I getting a sufficient ground for the...

Thanks for the responses. I will not be able photo the the panel until this weekend. I will post it for all to see.

I don't know if it helps, but the two wires are marked as "Alcan W 2 AWG AL XLPE 600W". Thanks for all of the responses.

It's actually a woodworking shop in the back and garage in the front. Most of my machines have 3- 7 Hp motors, so I dedicate breaker to them.

So does he have to tape the new #2 next to the 2-2-4 URD cable. This new #2 AL wire will be the neutral. I thought the four wires (2 hot, one neutral, and one ground) had to be together? Thanks.

Yes, I have three exposed ~8’ (2-2-4) URD wires between the subpanel and LB. Can someone cite NEC so I have something to show him the URD cannot enter the building? Thanks for the help.

Yes, the electrician terminated the two #2 AL (URD) feeders in my 200A breaker using extra pieces of #2 AL in the lug so he could tighten it. He did tape the extra piece of #2 AL so bare wire was not exposed above the breaker. I assuming this type of termination is not code. Can someone cite...

Does URD cable need to be in conduit from the LB to the subpanel inside the garage?

Building new detached garage and needed a 100A subpanel. The subpanel is being feed from the house’s 200A service panel with 100A breaker for the subpanel feeder wire. The electrician was going to install a 100A Square D panel with 20 breakers spaces. I told him I needed more breakers. He...

The electrician ran a 2-2-4 URD feeder to my detached garage 100A subpanel. After reading several posting on this site, I realized it's wrong and needs to be brought up to latest NEC. So now the electrician wants to bury a #4 ground wire between the house and garage. I’m assuming it's...
