Moving right along, we were well-prepared from yesterday. We have ballasts, wirenuts, quick-disconnects, T8F28 SPX41 lamps (nice bright cool white, 4100K. I hate the 3500k yellow crap lamps) to finish up the lamping project and replace all the
One fixture has 24" square U lamps, bad ballast in that one, no voltage to the "tombstones", at least not enough to fire off my pocket tester.
Beeps when near voltage over 90 volts, does NOT have to have
anything "on" in the circuit; just a path of available voltage, like a wall
switch in the "off" position; one side will be "hot", and make this beep and light up.
We didnt have any ballasts to power three lamps, so I had to use two ballasts that could be used for either ONE or TWO lamps, and stuff them in the fixture. Tough, but possible. Also had to rewire the "tombstones", because now the wiring is different. I also pulled apart the sockets to bend back the press-fit tabs. The wiring may come loose from these, or at times can be pulled right out of the "tombstone" when replacing a ballast and you wont even know it.

How I had to wire two ballasts to power three lamps. Just use both examples!
So, we finished up the rest of the day doing this. The Women's locker room is twice the size of the Men's locker room...there are also a half dozen toilets, nothing but a sink in the Men's room. I sure hope the men aren't peeing in the sink...but the sink in the Women's room doesn't work at all...so how are they washing their hands?
Eww...
One last tip for the day...
Cleaning the dirt that collects around the lines of flux.
Good idea to do this, black soot isn't a good reflector.
Formula 409 and a rag is good enough, and all we have at work
approved by entry into the MSDS system.
Wash your hands, kids. You're touching nasty things all day long that other people touched with pee-pee and poo-poo hands.
lol.
