So yes, 212 is close, but a hair low. But recall we are using Johns meter, which may or may not be traceable to the NBS and we've no idea if his single phase feed is up to snuff. If he only has 112 volts at a wall plug, either his meter is off a tad, or the power co. folks need to come out and raise his pole can by one tap. That likely will be a pull the pole flag and fuse, open the top of the can and actually move the tap which may be under 6" of what is loosely called crisco because it looks like Crisco cooking oil. BTDT, except I was dumb, the cans, because they were inside the building, had to have a fireproof oil in them, aka Askerol, aka the stinkiest damned PCB's, and it takes about a year to get that shit back out of your body after working up to your elbows in it for half a day. I made my youngest son not too long after that, and it was hell to get him to his 5th birthday, lots of trips to the Mayo Clinic. I will always blame the PCB's in my system at the time I made him for that. The 'crisco' cans used outside on pads or poles aren't a problem because that is just a vegetable oil. 127 has been the std here in the lower 48 for about 35-40 years.
