Any way to make 277V work on 120V?

My buddy just picked up a 277V ballast, and is curious as to how to make it work in his garage. Is there any easy way to rewire his ballast or something to make it work? If I were to just rewire the plug to a 120 plug, would it blow up? lol

not an electrician, but not a good idea. something is going to get hot, the ballast or the wiring to your house (read fire hazard). with electrical, if you are not sure dont do it.

You need a multitap transformer or a specific transformer.
I am not an electrician but i did stay at a holiday inn express last night.

lol the things you learn at Holiday...

Also, thank you for the clarification. I got the ballast that I'm running my MH on from a lamp post from an old local baseball field and rewired it about a year and a half ago. I checked it out last night, and it does in fact have a multitap transformer. Did some more research, and found these multitap transformers online for pretty cheap.

Here's a link for those that are interested in a DIY way to save yourself some good money on ballasts...

That's a good idea, I thought about that, but it doesn't seem very practical for a company to make the transformer multitap instead of just wiring it to the rating they put on the box. My buddy ended up hunting down the correct ballast on craigslist and is going to break even anyways. Good knowledge and nice little lesson in electrical, though! :P

Fuckin A man, if you're right that would be so legit. He just bought another ballast, and one for my 1000W is too expensive for my broke ass. Could be primo timing for the last few weeks of my flower :P . I just texted him lol
