So the PR power company LUMA is sending 130V/260V to my friend's house - saying they have to to get enough Voltage further down the line to neighbors. That doesn't smell right. They've been notified several times, but no results yet. Anyone have thoughts or suggestions - or just thoughts and prayers. :^)
@FireMonkey This is NOT my field, so YMMV. I would ask a master electrician or similar, but per the specs I can find online, this seems to be outside the acceptable bounds for the US based on ANSI C84.1, which appears to allow up to 126/127 volts as a maximum. Link below is a jumping-off point, but you can also find the ANSI spec by search. I am also unsure if PR is generally subject to the same rules and guidelines.

@codeWhisperer
That's also my assessment. PR does use the usual up to date US codes and standards, in a Puerto Rican way of course. Gracias por tu ayudar.
@FireMonkey Es mi placer. We're all in it together.
Actually, it sounds like you need this guy to come and fix everything.

I told her she needs a priest/electrician to do an exorcism.
@codeWhisperer
Her kitchen lights come on only when she turns on the induction cooktop and they get brighter the more burners and the higher the heat. I looked behind every switch and light fixture to try to figure out how those were connected, but the breaker box is too full of extra wire to even trace things. I tested a few breakers and looked for crossed connections but couldn't come up with a fix.
@FireMonkey @codeWhisperer I rented a room in Columbus where the outlet my clock radio was plugged in would occasionally go to 220. After buying me a third new one the landlord and I traced circuits and found that if the light in the seldom used third floor bathroom was on it would cause the 220. We reconnected the light correctly, problem solved. Good luck to you, but clearly the light and stove are in series somehow…
