I have a Energy Savings ballast just handed to me, it says
Universal Voltage
120 thru 277V 50/60 hz
.58/120v thru .25/277v
It has the CSA and the UL stickers on it now It was sent as a replacement ballast for some fixtures running on 347V. The manufacturer says all he sends as replacements are these ballasts for 347v systems in Canada. Now my question is , isn't the proper voltage and characteristics suppose to be on the unit before it is to be connected? Or is it because he has a CSA listing for the device and the light he sells rated for 347V is it legal?
