This may have something to do with the 50A GFCI use. When GFCIs were first called for on jobsites, 50-amp, 125/250V-fed "spider boxes" came with a single 5mA-trip protecting assorted 15-, 20- and 30-amp, 120- and 240-volt receptacles on the box.

It was a madhouse because any leaky 115- or 230-volt tool could dump the entire box; usually with a couple of strings of temporary lights included. There had to have been some bloody fistfights directed at those stupid electricians.
