Electric pool and spa heaters listed to UL 1261 are not required to have GFCI protection integral to the appliance but they typically have manufacturer installed leakage current collectors that provide a low-impedance path for leakage currents to ground.Click to see full answer. Subsequently, one may also ask, does a pool pump need to be GFCI protected?According to 680.22(B), all 15- or 20-ampere, 125-volt or 240-volt, single-phase outlets supplying pool pump motors are required to be provided with ground-fault circuit-interrupter protection for personnel. GFCI protection for pool pump motors is required whether supplied by receptacle or direct connection.Likewise, what size breaker do I need for a pool heater? Depending on the heat pump size, it will need a 30 to 50 amp breaker. If your pool has a 100 amp sub-panel by the pool, which many inground pools do, it’s possible that you have enough leftover ampacity available, to add a 30 or 40 amp breaker to the sub panel that’s already there. Similarly, you may ask, do 220v circuits require GFCI? I’ve seen a few threads elsewhere about this, and from what I can gather, you don’t need a GFCI for a 220v outlet; GFCI is only for 120v 15/20amp circuits.Can I use an extension cord for my above ground pool?It’s highly recommended never to use an extension cord to power a pump of an above ground swimming pool. A pool pump requires a great deal of power and that you can’t provide with a normal extension cord. You’d need one with a #12-gauge wire or a #10-gauge wire.
