Running power to shed

I have a shed pretty close to the house. I want some 120 power into the shed for nothing else than a 60 w light bulb and a socket for trickle charging my tractor battery. Question is, I have a junction box about 4 ft away from the shed and was thinking I should run some electrical conduit down from that box under ground and up into the floor of the shed OR bring it up the outside side of the shed to a disconnect box. Ckt is on a 20A breaker that runs porch lights and ceiling fans and motion sensor /spot light. Drooping a run to the shed seems like a bad idea?? tx

 

No, it sounds like it would be okay if those are the only loads.

 

Shed is hardie board. Suggestion for penetration if I use the droop method. Should wire be the underground type?? or use electrical conduit. or both. Tx

 

Strongly recommend underground. 24" deep if you use UF-B cable, 18" if you use PVC conduit. All receptacles in the shed need GFCI protection.

 

looks like HD has 14/2 50FT for about $29

 

That would have to be protected at 15 amps, but your circuit is 20 amps. You would need 12-2 UF cable if that is the route you want to go. I'd use PVC conduit with #12 THHN/THWN separate conductors. In the end it would be a lot easier.

 

OK... got it! Tx
