I need more juice for my 3 knc asics.
so I installed a 40 amp breaker with this wiring configuration
But my 20 amp breakers on my sub panel fail to initialize.
I am miss wired somewhere, but can't figure out where.
The gfci breakers have 2 screws, one copper and one steel. Copper has positive and steel has neutral. That's the only idiot place to screw up.
