Why would a standard 20A duplex receptacle trip the 60A GFI spa breaker (installed at service main)? Wiring is good, checked all connections, even megged out all conductors, no leakage. Circuit works great, powers/heats hot tube with.out issue, until I plug something into the maint recept... any sort of power draw whatsoever, the 60A breaker shuts down. Already swapped quad recepts for new, no difference.
maint recept is quad, fed off of A phase of 60A GFI breaker.
LED fixture above pedestal fed from B phase of 60A GFI breaker. Works fine, fully operational...
switch leg for LED fixture carried with 60A feed from pedestal to hot tub waterproof switch (in bell box, surface mount to tub wood-siding.
quad/LED connected via polaris, load side of standard 60A safety switch (also at pedestal), so as to be included with any safety switch operation.
tried multiple cord & plug load types, from smartphone and cordless power tool battery chargers to 6.5hp shop vac.
quad/LED neutral is #10 (not required for 60A spa circuit)
Also, I believe there's a section of code limiting circuit rating to max 50% if receptacle(s) added in series ...(?) (regardless, it should still work)
I feel like I'm missing something, but seems there's not much that can be missed with such a simple system.
