A new nursing home is having a high incidence of lighting ballast failures. The lighting is 277V. The ballast manufacturer thinks it is power surges.
I have two possible ideas:
1. The facility test the emergency generator under the building load once a month (the lights are on the generator).
2. I do not know, but maybe the contractor used a common neutral for the lighting circuits.
Any ideas?

Is this nursing home in york, NE??

The other possibility is that electronic ballasts are crap for reliability!

There is another thread here on this issue. Search on "electronic balasts"

Had an old timer come in the other day with an old GE ballast. I said "wow, that looks to be about 20 years old," he said it's closer to 50. I replied, well they don't last that long anymore. he asked why not?!?!? Couldn't help but be amused by his question, all I could say was they just don't build them like they use to.
