I just purchased a variable speed pool pump. I want to add a surge protector because of the electronics on it. I don't have any room in my main service panel, (Murray R256EB1A). So thought i would replace my old timer box with a sub panel at pump itself, about 100 ft away. My feed wire is UF 12-2 with ground so there is no neutral wire, 240 V. My questions are: 1) Best way to make room in Main panel and add surge protector? 2) Would it be better/easier to just add a surge protector in the sub panel? Is it possible to install a surge protector without having neutral wire in the sub panel? Can i install a GFCI breaker in the sub panel with no neutral wire? Would the breaker and GFCI connect to ground instead? The sub panel would feed the pool pump, 240V and a deck that only has couple lights on it.
I have considered putting Quadplex breaker in Main and combining 2 breakers to free up a 20A breaker to attach a surge protector to but have not found one compatible with my panel.
