I have been wanting another 25 foot extension cord for the garage and saw some on sale and was looking at them and decided on a 12ga cord. A guy standing there was looking at cords also and while talking I said that it would be a good one to take camping if you are going to be in a Campground with power as thy tend to be 20 amp. He said that it was still only a 15 amp cord
because of the plug and that the wire may be good for 20 amp but the plug would overheat and burn up. I said that I thought it had to do with the type of outlet it would fit in and that the plug should be good for 20 amps. So the other night I googled it for fun and found something about everything but that.
So can you overheat a 15 amp plug on a 12 ga. cord by pulling 20 amps through it?
I don't think so.
A 14ga. would have been been good enough for what I need but it was on sale for 15.00 so what the heck never been sorry I had more than I needed.
