I have a Glendinning cord reel and cord with 75 feet of cord,I plugged in on Wednesday to a 50 amp pedestal and in a few hours the breaker tripped,I reset the breaker and the plug was very hot so I ran the generator for an hour or so and plugged in again,and checked the plug with a IR thermometer and it was soon over 200 degrees.I replaced the entire cord and molded plug about 2 years ago because it was cracked,this time the plug looked good but there was something like tar that had run out of it.I decided to cut the cord and replace the plug which I did and the new one stays cool to the touch.I checked the old one with my ohm meter but I cannot find anything wrong.Has anyone else found a problem with the molded plugs?By the way I was pulling less than 40 amps per leg when the heating problem showed up.
