I'm thinking of doing away with my extension cord set-up to run lighting out to my wood cutting area. I have one of those 1,000 watt halogen lampstands which works excellent for lighting my work area in the winter evenings. However I have it plugged into 125 feet of extension cord (a 100-footer + a 25 footer). I would like to bury some Romex out to the site and have an outlet box stick up. Would 12-2 wire work?
