120 Volt Light on 277 Volt Line
I had a question I could really use some help with.
I work on Commercial Properties. We have been having some light fixtures blow, and been having an electrician come and replace them when they do. As you know that can add up over time.
So I decided to take a look at what has been done in the past replacing and try and replace them myself.
So today I looked up in the ceiling at a previous electricians swap out. He used this bulb and this can....
So I went to Home Depot. Bought myself the same can and the same light. Took out the old fixture and replaced with a new one. Turned on the power and my light bulb exploded.
Turned power back off. Looked around in the ceiling and found that the wiring goes to a junction box labeled 277 volt.
So my question is, if I am using the same exact can, and the same exact light bulb...then why is mine exploding on me, and theirs is working just fine??
Also for a little for clarification. The one I replaced feeds the one in which he replaced. So they are both in the same line. Both his and mine are wired identical. Black to Black. White to White. Green to Green.
And I checked to see after that if maybe there was some sort of step down transformer or something possibly he had wired into his, but no. Everything is wired in just like mine.
