I suppose it could be Andy, but in my 81 years, I've never had an Easter Monday off. That would be a new experience for me. In fact, I've had several Easter Sunday's that I worked. When the cash cow quits, you get up and roll to see what happened, when it happens. In one instance, I spent the entire day overhauling a GE AK-225 circuit breaker that picked sign on time on an Easter Sunday, to cook its contacts. The guts of that breaker, extracted from the housing, are about 60 lbs. A bit on the heavy duty category, it handles up to 1200 amps/phase, but in this case the over currant trips were set for about 650 amps. It was feeding the beam supply for a GE UHF transmitter, which was 3 ea 50 kw powerline cans wired backwards to send about 14,000 volts at 12 amps to the 3 phase bridge rectifiers that made the 19,700 volts for two 4KM100LA klystrons. Primary windings to the breaker and back to the cans were 2 ea per phase, of 750mcm cable. The transformers were filled with Askerol, aka 25 or 30 gallons of PCB's each. You might be able to find traces of pcb's in me yet as I have worked on stuff filled with it, up to my elbows, fixing a bolted connection that burned off inside one of those, and later, working on a Townsend TX, where all that stuff was in a big square can covered several inches deep so nothing could arc over. But you had to open the lid and fish out the rectifier stacks to repair them occasionally. You get as much pcb's in you from breathing the fumes as you get from getting it on your skin, where it takes about 2 weeks worth of scrubbing with boraxo in the shower before folks quit asking whats that smell. When that stuff was outlawed, and we couldn't get replacement cans filled with it, fire regulations meant we had to move the crisco (vegetable oil) filled cans we could get, out of the building to a caged area outside. That took a run of 6" conduit to get the power out there from the breaker, and a 4" run coming back in for the high voltage, using a special semi-conductor wire insulation with bells for corona control on the ends, designed for direct burial. The new cans were "crisco" filled, and needed 10% of the maintainance the Askerol filled cans needed, that crap ate the si rubber gaskets out of the top access covers about every 3 years. The si rubber seals on a crisco filled can will often last 50 years hanging on a pole in a residential area. You can probably see one of those from your property as the house drop comes from one of those. Just one of my "war stories" folks. I hope everyone enjoyed the reason for Easter.
