Converting detached garage to art studio/ apt. What is recommended conductor size to bring service from separate meter based on following:(1) approx. 70' including vert. run in 2' pvc, buried 2' to top. (2) anticipate 150 amp panel (3) My wife wants;tankless water heater, stove/oven, washer-dryer, wall mount a/c, lights and (she just threw this one in, maybe an electric kiln). I am underemployed carpenter/ general contractor and will have a real electrician doing the tie-in to meter can and figuring out the ground- neutral, sub-panel vs. main panel business but circumstances require me to do the grunt work.

You may need 200 Amps depending On Instaheat, and everything overall. Can you provide specs on what is intended. If you threw in a Kiln, and this is also work area, you might? Throw in a Welder?

I agree, we need some name plate information.

I like the fact that you are giving the remote structure it's own meter!

Unsure at this time what actual devices or appliances might be installed. Would want to err on side of excess capacity never, needed rather than ,"sorry Honey, the 300' of wire you just bought has to be pulled out and replaced with a bigger one". I know the info I am providing is vague ,but,at least I can start looking for conductor, factoring in cost and size you can stuff in a 2" conduit .

If you are even thinking about a tankless and a kiln forget 150a. Regardless, forget 150a. Either go 100A or 200A.

Also, a kiln could be 20A or it could be like the one I just wired at 75A continuous @240v. Just saying "a kiln" is useless.

I have to say, this is quite the ambitious project (read: $$$$$) for someone who is self-described as "underemployed".

The "tie-in" to the meter is the LEAST of the work and technical part. I don't know why folks think that is the only hard part.

You will 99.999% likely NOT be able to tie into an existing meter. Most residential meter pans only accept one load. To add to an existing service you will either need to add a meter or put in a feed-through panel outside.

O.K. 200 A it will be. When we purchased house it was a duplex, made it into single, but had extra meter socket installed .will feed through this meter for apt exclusively, so now, what would be the recommended conductor size to feed the apt panel? I am buying things piecemeal as I get the gelt, but need to keep moving forward with it , otherwise I'm just taking up space.
