I'm running 4 legs @ 125' long to the garage.( 10 guage THHM stranded southwire ) Two conductors ( hots ) One neutral and a ground.. I'm running them in grey PVC electricians pipe and putting them in a trench at 24" deep.. The 2 hots will be on a double pole 30 amp breaker which will run to a sub-panel in the garage.. The garage sub-panel will have one 20 amp breaker for 2 receptacles for well pump outlet and an outlet at work table for tools.. The other hot will provide for a 15 amp breaker for lighting, ceiling fan, and refrigerator outlet.. I want 220 / 30 amps out there in case I change over to something different down the road.. Plus, with the long run of 125' I need to suffice for voltage drop.. Please advise?
Question 1) I have a boat load of 1/2 inch grey electrical PVC conduit stock. (I'd like to use it ) If I cant fit the 4 wires or if its way to tight will it be ok to run the ground outside the conduit in the trench?
Question 2) Whats the deal with isolating the neutral from the ground on the sub-panel? ( NEC code )
Question 3) Many plain receptacles and switches are rated for 15 amps, but its safe to use them on 20 amp circuits - why?
Please advise and thank you for your expertise. You're helping me to save a few bucks and for that I am very grateful..
