My cold weather elec plugs come on around 40 degrees. Both bought at same time. Leviton 15a-125v at home depot. Anything more accurate to come on around 32 or 34? Or adjustable? Thanks
I've had terrible luck with the "Frost King" brand of those plugs which are common around here. They seem to be ok with the heater on 750 watts but if I put it on 1500, it kills the plug even though it's rated for it.
