Were they 120v ballasts on a 277 v system
Remove electronic T12. Throw in garbage. Put in T8. Lamp with 750 t-8. Turn on light. Looks good. Customer likes. Do more. Make money. Easy.five.five-six said:Simple right? relamped 2X4 troffer shuts off when it's warm. I replaced the tar t12 ballast with an electronic ballast, switch on, smoke comes out ballast goes POP! lights come on. I checked the tombstones and saw no signs of arching, I don't know what I could have done wrong. It says "use only rapid start sockets" what the ell are those?
120V system, multi-voltage ballast.Were they 120v ballasts on a 277 v system
I think you may have a faulty ballast , the spec,s on the ballast should tell you everything needed including wiring change you need to do with the sockets if I remember right.
Did you leave the t-12 bulbs in or change to t8?
They wont last long-- change the bulbsI left the T12s in. I almost changed him to t8s with new lamps but this guy is cheep.
I think we have a winner.Remove electronic T12. Throw in garbage. Put in T8. Lamp with 750 t-8. Turn on light. Looks good. Customer likes. Do more. Make money. Easy.
Sometimes. The times the switch is off it works correctly. It's when you go to switch it on that it's not working correctly.So everything is working correctly now?

No, I am not. Actually I was surprised they had one in stock.I understand you are trolling us
By not color matching, safe to assume it was dark right. :laughing::laughing:Seriously though, I am at a complete loss as how this thing blew up. The original ballast had 1 black, 1 white, 2 yellow, 2 red and 2 blue. New ballast had the same. How do you screw that up?
There was plenty of light to tell blue from yellow from red.By not color matching, safe to assume it was dark right. :laughing::laughing:
