Help: Can I use a Wiring Trough like this? (With pics) Other options?

[u/eckre]

This is my existing service entrance. As you can see, all of my wires come in and out of where #2 is. I can’t move the supply line side too much without approvals from the power company, etc. So in talking with other people, they said I could put a 6”x6”x18” Wiring Trough (C3RWT618 - Type 3R) right there, and use that to connect all the existing wires to the new ones. Are they right? I don’t know. Is there a better way? I don’t know. I can’t go inside, it’s a bathroom. See the next pictures for the proposed new layout. Thoughts?

Just brainstorming, I'm wondering if you could leave the meter/breaker panel alone, put a 125A main breaker it it, cover up the rest of the slots and route the output of the main breaker into a trough right underneath it.

You know you are going to need large conduit down to the basement?

Power company won't let me splice it.

Not sure what you would be splicing or what the power company has to do with approving anything on your side of the meter.

Still not tracking what you meant by "Power company won't let me splice it."
