I have just brought a lay-z spa & an external RCD 2 Gang (IP66) socket to power the spa. Anyway, i was thinking of spuring off a socket in the kitchen to feed the external socket, but didnt really want the external socket live all the time. So could I sumply get an extension lead, cut of the socket end, wire in the external socket and then when required plug in the extension lead plug into the socket in the kitchen? if so, would this effect the external sockets RCD function? one last question, I didnt realise that the pump/heater for the spa has an RCD plug attached and therefore would it cause problems if i had an RCD plug, plugged into an RCD protected socket?
