You could run a 10/3 copper loomex from a 30Abreaker in ur main panel,to a 6 or 8 breaker sub panel in or near your room. that would give u 120v and 240v ,enough to take care of any future changes ...and u have proper protection at your breakers in the sub...hope that helps
ReeferRick Reviewed by ReeferRick on . Can you run a breaker from another breaker if amps are same? I was thinking about running an individual break box w/ 10 or 12 gauge wiring from a dedicated breaker in my breaker box. My idea set up is this: 1000 Watt HPS 400 Watt MH 4ftx4bulb T-5 Couple big fans and a few smaller ones. Maybe a heater for out freezing cold winters... Rating: 5
