I am building a 1950 IH fridge smoker with PID and SSR control... I've searched for hours but have yet to find any suggestions on which type of wire to use from the SSR to the heating element. My smoker is 90% complete but I am worried that the wire that I used to go from my SSR to the element may be incorrect.. I started it up last night to do a functions check of the heating system and noticed that the wires going to the heating element were very hot to the touch after 5 minutes... I wired the SSR to the 1500 watt elements with high temp paired 12 gauge wire that is used on aircraft and is stable up to 1000 degrees F.. Everything else on my build is working great but I am hesitant to let the smoker run for very long and risk frying some of the electronics.... I've followed this forum ever since I started thinking about my smoker build when was deployed to Iraq and want to personally thank everyone here for all the suggestions and knowledge! Control Box with with timer, circuit breaker, PID, rotary knobs to turn off or adjust each burner for even heat, SSR, external outlet and 4 temperature gauges for meat probes: Just have to grind off excess high temp silicone then add a door gasket and door latches then its off to get its coat of LINE-X!!!
