Thanks for the suggestions everyone.
From the customer's information, and the previous EC's suggestion, I thought the customer's 120V spa needed to have a 30A circuit. After looking at it this evening, the 2 speed pump isn't dropping into low speed when the heater kicks on. So instead of the spa pulling 14A with the heater on, it's pulling 22A. Heater is 1.5 kW. Pump pulls 2.9A in low, and 11A in high.
I told him the spa would benefit from a dedicated 20A circuit and recep, but he'd need to have the spa repaired. As it is now, it's on a GP 15A circuit. I told the customer he should be glad the previous EC didn't have time to install a 30A circuit for his spa.
