Right, these breakers don't allow 2 wires. I plan on pigtailing a surge protector as you suggested.
I also plan on swapping out the upper 20A breaker, this feeds the pool pump, and replace it with a GFCI breaker.
Is it ok to put the surge protector on a GFCI breaker or will it cause problems?
Other option is:
I have a 30A breaker on lowest left I could put surge protector on, will a surge protector be effective on a bottom? Or should I swap these positions, even though it would mean another splice in panel, if I need to use this one?
