347 to 120 volt


I have a 347volt lighting ballast that I want to use in my workshop, but I'm unsure of what I have to do to get it to work on 120. Can anybody point me in the right direction?

Just buy a 120V ballast, that's probably the cheapest and safest option.

Unless it has multitaps(347, 277, 120V, etc) then that ballast is no good to you. Go buy the right ballast.

You could use a transformer to step the 120 up to 347, but the transformer would be more expensive than a 120 volt ballast.

I would pay for pictures of that .


you know you can buy a 120v flourescent light at home dept for $20? the ballast is almost worth more than the fixture.

Yeah for resdentail grade luminaires but for commercal / industrail location it kinda toss up depending on how bad and the condtion of the luminaire.

I just have one ballast changed in the spray booth that luminaire is Expolision proof but kinda tough to get into the ballast but got done changing it.

{ for readers the Explosion proof luminare will cost about 800 to 1500 }
Merci,Marc

the light in question is for his workshop so i'm assuming it's just straight forward....but i hear where your comming from...we did some lights for holding cells at an airport and being tamperproof they weren't real easy to work on. i'm still trying to find those code references for you as well.

Yeah I can see where this going and the last tamperpoof luminaire I have to use the special spanner wrench to get the bloody thing apart before I get the gaz axe { cutting torch }

For the code references naw no rush on that.

Merci,Marc
