So, what section of the code now dictates a 60A feeder to an 8 ft by 15 ft shed? NOT a garage, no vehicle storage, etc. Did not search too long, but then again my code interpretation skills are lacking..
Shed at church, 40 ft away from 3 phase sub panel with lots of spares.
Folks wanted a 20A 208v outlet in shed fro pressure washer along with 2 or 3 120 GFCI outlets and one LED light.
OK, easy, eh?
Wired it in -- a 20 A breaker in 3 phase panel, fed a 70 A panel in shed thru 10 AWG THHN in buried 3/4 sch 40. a couple of regular 120 breakers and one 240V breaker in the shed for convienience.
So, AHJ says: you need a 60A feeder for this, plus 2 ground rods, etc, etc.
Since I have always been a "kiss his ass and say 'yes sir'"' type and don't challenge the AHJ guy (never had any trouble with the female inspectors I've hsd<G>) I replaced the 10AWG with 6 AWG and added 60A breakers and the ground rods, obviously costing $$$ for 150 ft of 6 AWG copper.
