Hi. I am going to connect a 30 amp inlet box to my main panel and I would like to know the conduit size for the wires. I have 8 gauge wire. The inlet box will be located right next to the main, inside the garage. thanks.

and yes this is for a generator-- I have a square D interlock kit and a double pole 30 amp breaker. :smile:

A 3/4" EMT should be fine.

I went to HD, I saw "rigid" conduit. will that meet code also?

Rigid metallic conduit is too hard for a DIYer to use unless you have the proper tools for cutting, reaming and threading. More expensive as well. Rigid non-metallic (pvc) conduit is acceptable in most jurisdictions.

As an aside, DO NOT plan to use a generator inside a garage.

If this is going to be outside....and you can somewhat protect the conduit, I'd use PVC (gray) conduit. A lot easier to install and won't rust.

lol, yes I know. lots of inexperienced people do not know that....I do have much more experience with generators than most. I am a signalman for a class 1 railroad, so lots of experience wiring and running generators during storms. Since this is at my house, I am trying to follow code (not required at work).


one last question--I got a reliance 30 amp inlet box, inside the box there is a wire for grounding the box.Is that required?....wire goes from the L14 plug (G) to a little ground post on the box, then there is another wire on the post. I was just going to hook the ground wire from the generator cord to the L14 and unhook that, but not sure if it is needed. thanks

All metallic parts must be grounded.

thanks for the help.
