Replacing Low Voltage Can Light Transformer
Short story, a retro-fitting company( ie friend of mine), not licensed. Installed the wrong type of Occupency sensors in a beautiful multi-million brand new building and burned up 32- 277 volt low voltage magnetic ballast can lights.
He hired me to go straighten this mess out, my question would be, can I install a LV electronic ballast in each can? Should it be a manufacture spec transformer? or just any 277v magnetic trans? Or who knows where I can buy a 277v/12v transformer? |

Re: Replacing Low Voltage Can Light Transformer
My question is should I replace the ballast, with a direct factory replacement? So far the OEM has not returned my calls or email.
They use a magnetic 277 volt ballast, but it has to fit inside the fabricated box in the can, so it can't be just any ballast. I'm also asking if I can use a Electronic ballast, where is it defiantly smaller and easier to buy, but it is not original. I'm concerned that I replace these ballast, with non factory replacement, I might have some type of liability issues, that I don't want. In fact, I will write in my contract, no warranty, no responsibility for jack. |

Re: Replacing Low Voltage Can Light Transformer
Just replace all the fixtures unless you want to be held liable for re-using blown up hi-hats that some other "electrician" damaged badly and you rewired.

Re: Replacing Low Voltage Can Light TransformerQuote:
The fixtures are recessed 277v 4" IC rated can lights. New construction style, box style fixture, hard lid ceiling, no access above ceiling. Commercial office building. I appreciate your reply, that is a pretty good idea, not possible and a remodel would not be code. |

Re: Replacing Low Voltage Can Light Transformer
I'm sure your buddy would love you to do this as cheap as possible, but if you change those ballasts out with non-standard ones .. and they give problems.. is he that much of a buddy that he'll cover the costs for you to go back and replace them a second time?
If he is? ... send me his name and number, i can always use a buddy like that. IMO .. a ballast is a ballast, shouldn't make too much of a difference. However once you start putting non-standard pieces in fixtures your taking on the role of an engineer and CSA ( i'm Canadian ) takes a very dim view of that. The second problem is that God forbid there is ever a fire .. the insurance companies would eat you alive if they found out that you had replaced the ballasts with one that wasn't approved for that use.

Re: Replacing Low Voltage Can Light TransformerQuote:
Thank you. The manufacturing finally got back with me, so hopefully they will tell me where to buy them or send me some free ones. |

This is the fixture, very easy to remove. My buddy just found out he is not getting paid for this job, so I don't think I will be going back for the repair. Was quoted $30 per ballast =14 ballast x30= $420+tax+labor wow what a screw up. |

Re: Replacing Low Voltage Can Light Transformer
There's been a couple of times I've converted existing fluorescent cans to incandescent by opening the j-box from inside the can and changing things. It's totally do-able, so changing ballasts is no big deal. But not for free.
