just a tish NE of central ND
I have two different engine heaters on my 4320. The hose type trips the gfci breakers. The soft plug heater will run for ever on it .From what I can figure, the hose type heater takes a LOT more draw than the soft plug type and that is the reason for the tripping. Neither heater has the ground prong on them so it isn't a ground fault tripping the breaker in my opinion.
