I have an above ground pool in the backyard. There is a shed ~10' away that I am moving the pump and filter into. The pump is a 1.5 hp 120v pump, that draws 11 amps on high speed. I want to control the pump with Apple HomeKit. I have not found a HomeKit compatible pump controller. BUT, I have found where people use a contactor to control the pump and the control side is operated by a smart switch. I have the Lutron Caseta system in the house for several switches. The Lutron system is limited to 30' from the hub for the switches to communicate effectively. I am looking to install a smart switch in the mechanical room in the house and run a single wire from the switch out to the shed through existing conduit to an enclosure with a contactor. Please see my below crude sketch to clear up what I am saying.
Can I pass a wire through the breaker panels to get out to the shed? There is sufficient room in each section of conduit to stay within conduit fill requirements. I would use #12 THWN because the receptacle I would tap into for the switch is on a 20 amp circuit.
Is it an issue to use a circuit in the house for the control side of the contactor installed out in the shed? I would like to use the neutral wire out in the shed for the control circuit to avoid pulling another wire out to the shed.
