Disclaimer: Electrical work can be very dangerous! I did this with nothing more than my wits and a few books on electricity. Only do this project if you are familiar with electrical safety! I take no responsibility for any electrical shocks, fire, or damaged equipment. 30 amps of 220v power is enough to cause serious injury and even death. That being said, Ive run two of these at maximum capacity for the better part of year with no problems.
Not to mention in America it's required that you get a permit and have a license electrician do the work, this was if there is ever an electrical fire in your house due to your lack of getting a permit from the city and hiring an electrician your insurance company will walk away as they are not required by law to fix your house if you didn't follow the by-laws.
I knew someone who did this and suffered dearly when their wiring shorted out causing a major fire. Once the fire marshal determined it was an electrical fire due to improper wiring the insurance company asked the home owner to see the permits on the house, when the saw there were no permits they walked away leaving the home owner empty handed and having to fix/rebuild their home.
