Planning out my first build here. I am going to have a 5500w BK, 5500w HLT and 1500 seperate HEX for HERMS.
My question is, are contactors necessary? I understand that even though a PID will be telling elements to fire, without a switch in the ON pos. they will not fire.
What if I had a low voltage switch that either completed or cut off signal between PID and SSR.
As a fail safe I could just unplug that element.
This would save me $100 as I originally had a contactor for each element.
Thanks for your advice and opinions
