Electrical Extension Cord Requirements

[Dunner]

I use a 14 ga 25' extension cord to power my fridge and lights at home and I have two separate umbilical cords from the BatteryMinders in my garage. The 14 ga will power one AC unit and will get a little warm, but not hot.

Dunner You spent how much on a MH and you cheap out on an extension cord that gets warm. I have a large teardrop trailer and all of the extension cords are 10ga. Harbor Freight has extension cords that are genuinely 10ga. The electrical resistance of an electrical conductor is the opposition to the passage of an electric current through that conductor, in this case expressed as heat. At the worst it is dangerous and at the least it is wasteful.

I'm sure I'm not the only one that does this, just the only one that admits it. I'm 65 and haven't burnt myself down yet. The cord gets hotter laying in the Phx summer sun than it does in the shade with the AC on, and it's not even black.

A heavy duty extension cord will work just fine. Set your charger to 5 amps and don't worry about it.
