Hello,
I'm in the process of reworking all of my pool equipment and the electrical that feeds it on a repo home I purchased. Currently my 200 amp home service on a 30 amp dipole breaker feeds a sub panel (with no main breaker) that has (2) 20 amp breakers, (1) 30 amp breaker, and 1 unmarked GFCI. The panel is a mess and currently feeds nothing other than the 220v pump, the controls for a gas heater, and the timer that controls both. My pump is 208-230/115V & 7/12.8 amps. The heater controls are a small draw as should be the mechanical timer.

My questions are:
1. how much additional load do I have available? Do I count the pump as using 3.5 amps on each leg? so that would leave me 20.5 amps left for a 220v connection?

2. Does the entire sub panel need to be on a GFCI or just specific breakers?

3. A 30 amp double pole would need 10/3 feeding the sub panel correct?

This is a very old system that has not been cared for.

THANK YOU!!

NEC says maximum load on CBs shall be 80% of rated capacity.

24 amps for 30 amp breaker.

16 amps for 20 amp breaker.
