I agree with this, but you also have to install ground rods for the subpanel.Let me try and tackle this, and the pros can fix my errors.
AS IS: Your 30-amp Double-Pole breaker from the house will provide 30 amps of current to the shed (this should currently be ran w/ 10 AWG UF for the outdoor portion of the run). From the shed, you simply use the 15-amp breakers to provide several circuits.
Indicating that you want to provide 54-amps at 120v doesn't make sense at first, but I know what you want to do, I think.
What you should do is change the Double Pole breaker in the house to 60 amps, run three (Black, White, Red) #6 THWN-2 and a #8 bare
underground in conduit to the subpanel in the shed for your service, and then you can use the 15-amp breakers for your branch circuits, using 14 AWG (inside). Or, for the branch circuits, you can replace some of your 15-amps breakers with 20 amps, ran with 12 AWG Romex (inside).
Hope this helps.
It might but it won't be code compliant.One last question
Will 8-3 UF-B slide through 3/4" conduit?
Thanks for letting me know! I am having a very hard time finding what wire to use.It might but it won't be code compliant.
Why Not?It might but it won't be code compliant.
Code says you can put 5 #8 thwn/thhn wires into 3/4 pvc conduit.Thanks for letting me know! I am having a very hard time finding what wire to use.
So far I have been told that Romex is a no go, that UF-B is a no go, and I haven't gotten a clear cut answer on running 4 THHN wires. Is the only way to be safe to run 8-3 MC cable through a PVC conduit? I don't think it would fit in 3/4" conduit. It runs under quite a bit of cement, and I want to avoid running another underground conduit. I am not worried about inspection, but I want to be safe.
The cable is too large. 8-3 UF-B is 0ver an inch wide.Why Not?
Thanks JB! Very helpful! I think that is the way to go!Code says you can put 5 #8 thwn/thhn wires into 3/4 pvc conduit.
With one #10 and 3 #8's you should make it.
Make sure the wire is rated with THWN for a wet location.
MC cable would not be allowed inside the pipe.
It is fine as long as the pipe is proberly sized for the size of the cable.Thanks JB! Very helpful! I think that is the way to go!
To to be clear for the future, is UF-B just fine going through PVC conduit as long as it fits? Brric, you were just pointing out that 8-3 UF-B wouldn't fit through 3/4" conduit, not that UF-B is generally against code? Is that right?
Gotha! Just came down from working on the roof, so the brain was a little fried!The cable is too large. 8-3 UF-B is 0ver an inch wide.
And the #8 being run in conduit has to be stranded. The #10 for ground can be solid or stranded.Code says you can put 5 #8 thwn/thhn wires into 3/4 pvc conduit.
