I first noticed that the snow had melted where the 2 cords joined, but
didn't think much of it as it was before I had gotten the bill. The
junction was in the clear then so any leakage could have been transient.
Besides, this cord is on a timer and only runs 2 hours a day to power a
block heater on the school bus. It comes on 1 hour in the AM prior to bus
startup time and 1 in the afternoon, although often the heater (1000
tested kw) isn't plugged in during most warmer afternoons.
I tested the cords and the heater 1st thing with my kill a watt as it was
suspicious to me also.


Was the cord coiled up making an electro magnetic heater?

I'd be suspect of the cord setup as then can generate a lot of heat. Years
ago at work had one start to smoke plugged to a truck block heater. Where
the cord was coiled, it go damned hot and that heat translates to energy
use.


Not coiled, but loosely tied in an overhand knot to keep it from
inadvertently getting pulled apart.
