Pool man says disconnect not required in 680 for pools...timer and switch meet requirements...but they can`t be locked in the open position.Now I haven`t done a pool before and didn`t see in 680 the requirement but I`m sure 430 would apply for a motor.I put the disconnect.Like I said if home owner not home you can kill power to timer,switch and motor for service.He says sounds great but not required.So I`m hoping to convince him.
PS they sure are proud of those bonding clamps ouch $$$$.
