I'm in the middle of installing an Intermatic PE635 automation system. The instructions call for the spa blower to be connected to the breaker for the main pool pump. This is necessary because of the way Intermatic does the wiring for their control system. In the past, the blower was on a separate breaker, but that is no longer an option if I want to use the automation to control the blower. I'd like to hook the following up to the main pump breaker:
1) Spa blower - as stated above, I have no choice if I want the blower controlled by the automation system. Amp draw: 4 amps
2) Main pool pump - Amp draw: 11.5 amps
3) Stenner Pump - don't I also want this connected to the main pump breaker as I don't want the Stenner to operate if the pump is not running?? Amp draw: 1.7 amps
4) Raypak RP2100 heater - this was hooked up to the pump breaker originally. I'm assuming it should be connected to the main pool pump breaker also as you don't want the heater to run if the pool pump is not running. This is a propane gas heater and I'm assuming the amp draw is small, but I can't find the amp draw for this device. This information is not contained in the instruction manual and I have not been able to find it on line.
My main pump breaker is 20 amp and with this setup I'll have 17.2 amps plus whatever the heater is. Is this too much on that breaker?
If it is too much, any suggestions on what I move to another breaker? I'm thinking my only option would be the Stenner, but that does not remove very much amp draw?
