In case you ever wondered, the voltage used for T1's is a lot.
180 VDC to be exact.
I didn't know that until today, and while trying to simply measure the voltage, I did something almost as dumb as the time when I shorted out a screw driver against a Unilux light in the attempt to repair it. Quite the experience that was.
Today however, I rested my index finger against the posts of a 110 cross connect block and, well, let's just say that I wasn't pleased with my choice of places to put my finger. 184 VDC is the actual voltage on these two posts I touched and it bites. Don't try this at home. I'm serious. ;)
