Electrical questions

[Bigredford]

I'm building a shop and living space in a 40x100 building and doing all the work all myself.


In the living space I have a 150 amp panel. It will be fed from the main panel in the shop. Wire will be run in conduit until I get into the living space.

At that point can I keep running the thhn wire to the panel or do I need to change over to use cable? Continuing the conduit isn't really a option unless I use flex.


As far as afci circuits....what else needs to be afci besides a bedroom?


I posted this on Facebook and the answer is to hire a electrician. If it was conduit all the way or seu cable all the way it have no question.

You can't run single conductors without conduit.

As far as AFCI requirements - that is up to the local AHJ and local codes. Local codes often lag behind national NEC. And some make modifications - sometimes more or less strict.

Thanks. Sounds like I should email my building inspector and find out what I need with the AFCI

Definitely. Cost difference could be thousands.... literally
Also verify what they allow you to do and what plans they need for the electrical. If any.

as said above, individual conductors cannot be ran without conduit.

single rated USE wire is not permitted indoors.

You could transition to SER in a junction box which does not need to be in conduit. However it cannot go underground

BTW, you will need THWN conductors for underground use but most THHN is dual rated...

SER would be my recommendation as well. Everything is within the building, so I don't think he's doing anything underground.
You could run SER straight from one panel to the other without junctions or conduit, as long as it's not subject to damage in the shop.

Georgia has adopted the 2020 NEC, so start planning for lots of things not required before.

We use a PVC coated MC cable for aluminum feeders in Canada (we call it ACWU) - cheapest way to run bulk power. Can use it outside or inside, and is considered mechanically protected enough (in normal areas) to run on wall/ceiling surfaces.

Anyway, thought I'd mention it in case its available...

Why not make a transition from conduit to flex? All you need is a rigid coupling with a flex connector screwed into one end and a conduit connector in the other. You could also set a junction box and run SER from there, but the box and the splices won't be cheap. I wouldn't run SER all the way unless it's inside the walls. That will look like **** where exposed and you will cuss yourself every time you look at it.

Unless you have no soul. Then it wouldn't bother you at all

Didn't realize we had changed to the 2020 code. My code book is for 2017.

Honestly had not considered using flex where I can't run the emt.

I've got some pull boxes. Smallest is 16x16 inches.
