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.
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.
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.
JohnJ0906 said:It will be fun changing those ballasts.
Actually, damn near impossible.
You removed it through the 4" recessed opening?I removed a ballst out of one, it is actually a good design, to work with.
This is the fixture, very easy to remove.
He's not being paid for the job, or not being paid to fix the screw-up?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.
