Supergun and AC power question

Okay, I have completed my supergun, but I use an external arcade power supply. So I want to mount a circular connector so that the power wires can be plugged an unplugged, right now they're hard wired. Because on the supergun I have the "live" wire from the wall (AC) going through it, I need to make sure it is safe for the circular connector to carry AC current.

Are there any special connectors I need to run AC? Minimum guage requirements or something? I assume I can't run live AC through a regular Dsub connector without melting it...any help?

Oh yeah, and it needs to support 7 pins at least, only 2 of them are AC, the rest are my grounds and regular arcade power supply DC output.

Thanks guys.

If you look in the parts thread you can use a 5 pin din jack. The pins are strong enough to handle the current.

Thanks man, you've been a big help with all my questions lately!
