Sub panel install question.

[rbragg]

I have been building a house. While building I have run a 100 amp sub panel directly off my meter. Now that the house is almost done I will be wiring it directly into my house panel. My question is.

My panel is on the outside of my house. I have a knockout on the side big enough and almost a strait shot to the breaker I will be using. I was thinking about using a 2 1/2 in conduit body to tie into the side. Then run to my 2 1/2 in conduit.

When I mentioned this to my friend (He used to do electrical in the oil field)he said to go into the bottom. I have two issues with this.

1-no knockouts are big enough

2-bending the wire I have 90 degrees will not be easy.

My friends issue with going in the side is water leaking. So I guess my question is will this be a issue? Or is there a way to make it not a issue?

Thanks

Get another opinion from someone who can put eyes on the job.

Watertight hub.

A panel coming directly off a meter with no disconnect between them is a main service panel and should be wired with a bonded neutral not wired as a subpanel.

Now that you have a main service panel, you need to make sure the subpanel has an isolated neutral. The feeder will need to be 4-wire. you will also probably need some ground bar kits.

Tighten the locknut it wont leak. They are done this way all the time.

The KO needs to be below the live parts for the locknut only installation... Otherwise you need to use a watertight hub or similar fitting.

I think they are low on the side for the RB boxes.
