I just got my approval of my rough electrical. I have a Pentair IC40 chlorinator, a Hayward EcoStar SP3400VSP Variable speed pump, and a Hayward H2500FD gas heater. I was going to wire all three of them to an on/off switch. So they all turn on and off together. Is this the correct way to do it? I saw it done this way on a different pool that was put in my sub at the end of fall last year. Any help would be appreciated.
