Extension cord wire size?

[Echo]

I like the romex and outlet solution...

the less that outlet shares with, the safer you will be in the long run. I also opt for the dedicated circuit. this way at that location, you can upgrade to anything you need. As for extension cords I don't own less than 12 ga, and often use 10ga. and I wired my house for many of the above reasons.

Anytime you introduce an extension cord to a Lead Pot, it's asking for problems. And at 50' could start a fire. Personal advice would be use a minimum of 12ga copper wire and put an outlet where you do your casting. I've seen extension cords melt, smoke and catch on fire, it's not worth the possible consquences. Just my personal thoughts.
