So I stopped by a garage sale and it had a locking 3 wire plug along with roughly 10 feet of 10 gauge 3 conductor wire. They were reasonably priced and I thought they would work perfect for hooking up to the heating element in my brewing system I am planning.
After looking closer, it seems these devices are rated for 125V @30A, and have a slightly different orientation of the locking pin.
Link on Amazon to what I bought: link

is there honestly anything different internally that would make the 125V not capable to carry 125V on two separate wires thus making 250V? The wire itself is insulated and no big deal there. Just wanted to see if I shouldn't worry or if there is something I am missing
