I would like to relocate my main 100Amp panel to the inside wall of my garage.
Code saids the main panel must be on an outside wall. What I was thinking of doing
Is install a New Main panel on the inside wall of the garage and put a 100Amp disconnect at the old panel location. I am aware of needing isolated Ground on the New Main, I believe the
Ground are all tied together at the 100Amp disconnect. The New Main panel has a 100Amp main in it,there would also be a 100Amp main on the Disconnect?

Any thoughts on the this?

The old main is not a good place to get at in the garage, It is also a Federal Pacific panel with 20+ breakers and no main disconnect. It is the way the house was build. All copper wire in house.

I would do it.

-When you say code states that the panel must be on the outside wall, are you referring to a local code? NEC states that a service can be located inside or outside a building or structure--near as possible to the point of entrance of the service conductors (See NEC 230.70(A)(1)

-A 100 amp disconnect works fine, but a waste of money if your local code doesn't require the main service disconnect outside.

-Yes, at your main disconnect or service rated device, you will have all grounds tied together. You will separate the grounded (Neutral) conductor from the grounding conductors at your sub.

-Good thing you have copper. When you say the old main is hard to get too. What do you mean? If you plan to install a new panel, then you must keep in mind your equipments work space. ***Note: Some AHJ will allow you to place a new panel in a space that doesn't fully meet the work space requirements, due to existing reasons. (example: structral)

Thanks for your input. The on main panel is in the back corner of the garage. If I move the panel it is a little more accessible, not muck but all the wires will fit with out having to extending any of them.
Thanks again for the nice answer. I think I will drive a new ground rod while I'm at it, there is a ground on the old panel but I'm not sure where it goes to ground. The closest water pipe is 20 feet away.
Thanks again.

Wow!
I rest!
