Installing a 100 amp Subpanel in garage

JasRam · Aug 13, 2022

Hello All, Just looking for a bit of advice on the diagram I have laid out for adding a 100 amp subpanel coming from my 200 amp main. This will be going to an attached garage that requires about 45 feet of wire. The garage is drywalled, so I will be using conduit over the existing drywall, as I don't mind how that looks. Sorry for the rough drawing. Does the drawing look accurate, of would you approach this in another way?

Not sure why this was moved from the DIY forum?

We have a US forum on here. A couple of members are from over there and will probably check the US section more often.

Your sub panel needs to have a neutral bar which should come already installed and a separate ground bar which usually you have to install. It looks like that you have a main lug only panel which is fine with a 100 amp breaker feeding it. You must keep your neutrals separate from your equipment grounds.
