I have a 277 v. light that has (2) 32 watt 4 pin lamps. Right now it has (2) ballasts and I would like to make it a (1) ballast fixture. Each lamp socket has 2 red wires and 2 blue wires. I bought a new ballast that is supposed to be rated for two 32 w. 4 pins. The ballast has 6 stab terminals, 2 blues, 2 yellows and 2 reds, along w/ h,n,g. The fixture does not have any yellow wires. I'm wondering if I can make it work, or if I need to stay with the 2 ballast system. If anyone can answer this but needs more info, you can email bighitter0008@yahoo.com. Thank you.

2 Ballast with just 2 tubes?, sounds like one of the Ballast may be a battery backup ballast seeing how many leads you have and only 2 tubes, if you could post the model #'s for the ballast it will help greatly.

Here is how to connect your ballast. The red wires connect to one socket with one wire on each side of the socket. The same goes for the blue wires.
The yellow wires are connected to the other 2 sockets with one yellow wire connected to each side of each socket. The yellow wires supply both of these sockets.
Make sure that you have the correct lamps for the ballast you have selected.
Be sure to turn the power off before you start work! 277vac can be very deadly!

Sometimes you can rewire a fixture to go from 2 ballasts to 1, but it depends on the fixture as well as the type of ballast.
The ballast itself should have a detailed diagram on it showing the appropriate wiring. It generally involves rewiring of the sockets. Not too difficult if you're handy. Careful though cause it's 277V.
Good luck.
