Evening folks,

When unplugging the space heater cord, it was very hot, the plug itself and about 12- 16 inches down the cord...hotter toward the plug.

It was turned off before unplugging. It's a 1500 watt heater, pulling 12.5 amps (using 120V).

Is my math right, only .5 amps short of being over the wires rated ampacity? The blades of the plug are clean, no obvious signs of heater probs. Same results in 2 different plugs on 2 different circuits.
What do you guys think? Heater unplugged for the time being.

Thanks,
Alan
