Thanks for the quick replies.
To answer a few of the questions:
ComEd tells me 127 VAC is their high limit.
The power conditioners I'm using are made by UltraPower and reading 129 VAC. They indicate that the voltage is "unusable", and are being prevented from operating at all. UltraPower says the units won't operate at voltages greater than 127.
Light bulbs are a pain, but the least of my concerns. I'm transplanting a home music studio into this new house and can't get it powered through the conditioners...which tells me I definitely don't want to plug the studio equipment direct to the wall.
I'm becoming a little concerned about basic appliances as well. How are my kitchen and laundry appliances dealing with this additional current? Are my TVs, stereos and computers going to die premature deaths as well?
