In my experience with that.... I would say you had a 100 amp service. You would need to add a double pole single throw breaker,It should be 30 or better. If wired for 220. Count the amps on the breakers that are there now and see if they add up to 100 or more..Or look at the main breaker and see what it says on the switch. If it's more?Then you would have a 200 amp panel. You could add the breaker then..
GaGrown Reviewed by GaGrown on . 110 vs. 220 im kinda shocked i have not found a thread about this but basically iv ben hearing if i want to run 1000w bulbs i should run a 220v because its cheaper for the electric bill basically trying to see what people think...and could i get away with just using a 110 and upgrade later if its really worth it Rating: 5
