63.75A?? That's what Chelan PUD considers "far above what residential wiring is designed to carry?" What a joke! Nearly all modern homes have at least 200A service and even the most ancient breaker I've ever seen is designed for 100A. If it was the actual wiring from the breaker to the receptacles they're talking about that's just shitty wiring that's not up to code. It has NOTHING to do with mining. Anything you plug into an outlet with faulty wiring is going to cause a fire.
It depends on the apartment - I've SEEN quite a few apartments in the area (I'm next door in Grant) that only have 50 amp service, and remember many others in other parts of the country.
If it was an apartment with 100 amp service, IMO the renter has grounds to file CRIMINAL charges for "making false accusations" as well as a big fat lawsuit for breach of contract and refusal to provide services.
If it was an apartment with 60 amp or less service, the renter should be in jail for criminal endangerment, in addition to facing a lawsuit and fines.
Power is NOT provided in the USA (except for a very few ancient LEGACY cases involving stuff that was originally DC powered and often close to a century old) at 117 VAC.
It's provided at 234 VAC "split phase" aka center tapped, and has been that way for decades.
The one that is still BOTHERING me *BIG TIME* is that one homeowner - who DOES seem to have grounds to sue based on what little has been reported on that case.
I also have to wonder if that homeowner has thought to file a complaint with the Washington State Utilities and Transportation Commission, or with the part of the state Office of the Attorney General that deals with utility issues, or BOTH.
The "power you pull when cooking a family dinner" is going to be somewhat less than 6 KW on average, as most electric ranges have 6 elements (one top one bottom in the range, 4 on the top for cooking with pans) at 1000 watts per element - and those elements turn OFF once they hit the "set point" temperature (more so on the oven, though the stovetop elements are easier to see).
That's assuming an electric range (a SAFE assumption in Central Washington except for places like Burger King due to the very low electric cost and lack of any local natural gas sources).
Most apartments have a "kill switch" somewhere before the panel for each apartment - it's POSSIBLE to replace a panel without shutting down the feed from the power company, but still a very UNSAFE idea as the wiring won't be sized correctly unless you are replacing the panel with a "same capacity" setup because the PANEL is going bad (it happens, but we're talking typically quite a few DECADES, or a panel that water wasn't kept away from and is rusting out).
