That reminds me of a sparky I knew who had 8 kids and seemed to ride out layoffs as if by magic.
In retrospect, what frustrated me about him was not that he did things wrong, but that he chose to do the wrong things.
E.g., to run a DC linear actuator, he chose to design a power supply from scratch, rather than buying one, or just buying a car battery and a float charger. That last would have been the best option because the actuator required >250 amps to start under load (which it had to do in our application), vs. its nominal current requirement of about 20 amps, which is what our magic power supply was designed for. The power supply worked great on the test bench.
