Most pumps are hardwired, but I'd like to to have a physical disconnect between the power center (Pentair EasyTouch) and the pump (IntelliFlo). It doesn't seem like anyone sells a outdoor weatherproof receptable for 230V -- the Hubbell Bryant kit for 230V is discontinued and they only sell the 115V version now. Can I just buy a marine-grade locking plug and receptacle for 230V (NEMA L6-20 or something like that) and connect things this way?
