	Contact a qualified electrician to wire up your transformer. If you don't understand the basics of this you can kill yourself or someone else. __________________ Perfection is achieved, not when there is nothing left to add, but when there is nothing else to take away

	Hello "Guest", As we don't know your Location, Country, and likewise your local Electrical Regulations, it would not be proper to advise you. Reply here, with Kind Regards.... __________________ "The number of inventions increases faster than the need for them at the time" - SparkY

	Hello Guest : Do you have access to the nameplate on the transformer? If so, does it indicate a diagram with an equilateral triangle and a Y with a ground symbol ? And does the nameplate indicate the voltage for the primary, as well as the secondary ?

	I definately have to agree with Shawn and Sparkstation!!!! 1st off you should read around 125 on the single phase and around 240-245 phase - phase. electricity is NOT a DIY subject matter! There are plenty of QUALIFIED Electricians worldwide to help you. Please call one. __________________ Tell 'em what they need to hear; not what they want to hear!
