I've stretched out Google (edit: and also checked a Lowe’s) but can't seem to find any replacement plug heads for what I am pretty sure is a 10 AWG extension cord which came with our used RV. (Edit: The jacket does not list the wire gauge.) Best I can find is 12 AWG. The plug head is missing the ground pin which causes it to slip out of the outlet too easily. I'm hesitant to cut the outer casing to confirm it's 10 AWG but the diameter is about 9/16ths of an inch which matches what I've seen 10 AWG cord is. And I don't want to cut the head to attempt to mate it with the common 12 AWG replacement heads because if it doesn't fit, it would ruin it.
So. Anyone know of 10 AWG replacement plug heads?
Standard replacement NEMA 15A rated plugs will generally accept larger than 12Ga wire as long as it is a clamping arrangement.
I just mated a cheapo Harbor Freight NEMA 15A plug to a piece of 10 Ga building wire and it fits and clamps fine.
Here is pix of the plug and wire..
Although, I wouldn't suggest using a HF plug for this application since you are using as an extension cord for your RV as they are pretty cheesy on design quality.
For your application, any of the name brand plugs found at Home Depot or Lowes should work fine.
