I have a 25K gallon in ground pool/spa with Pentair equipment (VS pump, booster pump for cleaner, matertemp heater, led lights). All equipment is run through an Easy Touch 8 control load center. The load center is connected to a double pole breaker (50/50 amps) in my main house panel. The load center has two double pole (20/20 x2) and one 20 amp single pole breaker. I have recently build a shed around my pool equipment and my question is can I add a new 20 amp breaker to the load center to power an outlet and light for the shed? The load center has room for the new breaker.
