Ok here's a question for yai am a newbie to growing and to rollitup but i am an electrician with over 15 yrs experiance and as i was looking thru the threads i saw a few electrical quistions so feel free to ask any electrical quistions and i will try to offer any advice i can.
well depends on what type of appliance do you got? if it has a regular type plug then all you need to do is change one wire to a dirrerent spot in the breaker box.but that will make all the plugs on that breaker supply 220v.
but to give the proper advive i need to know what it is your trying to plug in so if you will get me that info maybe i can help.
