Power cord wire sizes

The power cord is 12 gauge wire. We have replacement Power Cords available at Rad Rays (410)737-4404.

Correct, it is 12 gauge. I got the same type and guage cable from a local electric supply place for $1.00/foot. I bought a 250' spool, the crimp connectors to the breakers and plugs to replace them (I reuse the strain relief). I can replace about 10 for the price I was paying for just 1 before.
