Change of Plans - Shed Wiring
Thanks to all who responded firstly....(for those of you who haven't seen...see shed wiring in recent post)
Now onto the possible change of plans (plans changed due to advice my bro-n-law received and I'm helping him).
So now he wants to feed his shed (structure separate from the house containing two 20 amp circuits) with one 30-amp circuit from his house using 10 ga wire and installing a subpanel at the structure instead of using a double pole breaker and 12/3 wire.
Questions: 1) Can one 30 amp breaker/circuit run to a subpanel feed two 20 amp circuits?
2) He's gotten the ok to use THHN instead of THWN. The wire will be run in conduit along a deck for part of the way then buried about 15 ft before hitting the shed. People on here say to use THWN, but the two guys he's talked to said THHN is fine. Thoughts?
3) Will that new subpanel in the shed need its own ground rod or is the grounding wire run from the house sufficient?
4) Would you use a single pole or double pole breaker?
5) Where would you put your gfci protector. At house using 30 amp gfci breaker? At subpanel using two 20 amp gfci protectors?
Thanks in advance....as with most other house projects....this seems to keep growing.
