SCRs. Just turning on and off 480v at around 1200a.
Sucker was 6500lbs. Which may not seem like a lot. But when it's shoehorned in the most inaccessible part of the plant (nothing compared to the 53rd floor back closet of the Sears tower like Joe is used to), it makes for a difficult placement.
This HX & pump skid package was not light either.
I always end up working with **** 25' in the air.
I'll have 140+ hours on this paycheck for the last two weeks.
In case yall wonder how i can afford so many toys, now you know.
This is why I think the Internet Of Things is ******* stupid.
When was the last time you updated the firmware on your doorbell/fridge/drier/lightbulb14? Until I'm wealthy enough to have an InfoSec dude on staff, I'll live in a dumb home. And I'm not going to hire an InfoSec dude until I hire a chef, and at this point I don't even have a maid.
Maybe I should start looking for a lawful-evil mage for hire to start....

I was on a diesel-electric ship with liquid cooled SCRs. Before joining I was sent to training at ABB in Singapore. I was very leery of having water in close proximity to such a high voltage. One little seal failure and BAM!

There's a lot of mind-blowingly large hydraulic stuff up on the 104th and 105th floors of Sears. A combination of elevator machinery and cooling equipment. Fortunately, very little of it is my problem. I have one equipment rack on 104, plus four steerable 2/7ghz microwave antennas and two cameras up on 105.
The cool stuff is on 100. Presently, my 20 year old transmitter is down on 98, and we have our own dedicated antenna on an outrigger at the base of the west pole. We're building a new transmitter suite on 100, and will be joining the new combined-antenna group which is near the top of the west pole. There's a lot of loss in the combiner, so I need to increase my power output from 20.5kw to 38kw to compensate, but the extra elevation (and not having the base of the pole as an obstruction) should improve the signal.
Here's the new combiner which we'll be feeding:
It's at the right side of the picture. You know the little 6-way cable splitter you have behind a TV somewhere? This is the exact same thing, just rated for about a megawatt total power.
Better view:
One of my soon-to-be neighbors, who already has their new transmitter up and running. This is one of their two coolant pump rigs. Each rig has two pumps which run in parallel, and the two rigs are redundant:
Mine will be far smaller. We're down at RF channel 19, so I need a lot less power to make the same effective coverage. These guys are putting out about 90kw total.
At the upper-left is my west-facing microwave antenna on 105. This is for receiving the signals from the news trucks and the helicopter. It's aimed at an exterior window, although the glass is covered in a rubber spray-on coating, both for thermal rejection and also to resist shattering in case some dumb ******* (like me) accidentally knocks something heavy like a big antenna against it:
