New construction electric


Hi. The foundation crew show up next week to begin on the foundation. Is there any electric work that has to be done before, during or right after the foundation. Don't want to spend my weekend chiseling concrete .
Thanks.

Unless you have any outbuildings, well, and/or septic, not really.

If you think you'll do something in the future, like a detached garage/shed or a post light, I guess it wouldn't hurt to stub a pipe through.

Yikes, I didn't think of one of the most important things. You can tell I don't do new houses but, if i do, I hope I don't forget that

If this is a slab, you'll need conduit for the kitchen island and any floor box receps.

If it is a slab you can do alot more than the floor boxes. You can stub up for all the recepts on the main floor. Saves on materials. Do you require a foundation bonding grid? I think it may be required but not sure. You do have a licensed electrical contractor on this right?

Is that a question? Because I was just going to ask.

From what I can see and understand in my quick internet research into what a Ufer ground is, I can see that A) it's required in a few jurisdictions, particularly where soil conductivity tends to be poor, B) generally a good idea anyhow, and C) despite the above, still fairly rare in residential construction.

I belive one of the guys here is from Minnestoa he can able confirm the answer the question you are looking for.,

However with the UFER I will go that route My state code { Wisconsin } Do require the UFER on new construction for all type { yeah resdetnail guys pay attention to this details and of course commercal as well }

The UFER work heckva alot better than ground rods as long you have proper cement footing as long it is not complety enclosed with plastic vapour barrier { there is detailed info but I don't have the photo what it should be look like }

And with UFER you can use half inch ( 13mm ) rod and stubbed out but that rod it must have at least 20 liner foot to order to use it effectently.

Merci,Marc

I am pretty sure romex is less expensive to install than pipe and wire.

What about the labor and materials combined. I think you would work less and spend less if you put as much as possible in the slab. Future work will also be much easier. He only has one opportunity. Just the way I would do it.

He's going to have a full basement. Thought I remembered the OP's name -- he said that in an old post.

If full basement do you need to put conduit and boxes in the wall forms before the pour? I guess it depends on how it's going to be finished. My basement walls have conduit and boxes in the concrete because the walls are just painted. If they will have frame walls built in front of the concrete then there's no point putting the conduit and boxes in the concrete.

If you want an outside electrical outlet on any above grade basement walls now would be the time.

Isn't the concrete encased electrode (UFER) required everywhere under NEC for new construction or have some areas not adopted it? Seems like it sure beats driving ground rods.
