It's what called a back door rate increase LOL. Seriously that is way too high for any house. 120/240 should be a mandatory upper voltage limit allowed for residential service drops. Anything above that is waste as it generates heat and nothing more.
I did fine till TVA ran a 180,000 volt transmission on my place which feeds the new substation my utility built two miles away. When the line was finished the utility to pay for it jacked up the voltage from 115/230 to nearly 130/260. They can't say it's harmless as it leaves no room for surges. Things began burning up and I began checking. At first I thought my Volt/ohm meter was out of whack till I used a second one that confirmed the problem. The utility director tried to tell me it was for future expansion etc and I said B.S. come and fix it or I go public.
how can I check this out? I’ve got bulbs that are supposed to last for years, burning out in a couple of months.
