I have a 600 MH Digital Ballast and my power cord that plugs into the wall socket and the ballast... well the side that connects into the ballast is loose, so I basically have the cord jimmied against the wall to keep it into place.. it is a 300V 14AWG cord. Can I replace that cord with a 300V 3C/18AWG cord? Really don't feel like burning down my house for the next while, lol. Thanks for your responses.
