Please disregard the post immediately above this one. I meant to post the following.
I guess state governments can attempt to regulate and dictate anything they would like.
That doesn't mean that their regulations are followed or for that matter even make sense. In this case, some of the listed regulations are not realistic and they certainly do not make sense. If you live outside of a city/residential area is it ok to have 132 or 108 volts at the meter?(+ /- 10%) That's what the regulation says. Will my appliances be able to work properly and safely at these extremes? Absolutely not.
I live in a very rural area and I'm served by a rural electric co-operative every day. I've had 128 volts at my meter before.(I monitor the voltage at all times to protect my equipment) One call to the REC office resulted in a troubleman at my door in less than 90 minutes. The troubleman informed me that 128 volts was not acceptable. He corrected the problem right away. (regulator left in "manual" at the substation...)
Let's talk about practical real world things here. I firmly believe that most people who view this forum regularly do so to learn what is practical, safe, and real world, not what some obscure and obviously foolish state regulation says.
Governments can do whatever, but no power company that I've dealt with (granted, I have not dealt with every single power company in the U.S.)
would allow a residential service voltage to persist outside of plus or minus 5% of the nominal center of band . To do so is outright stupidity.
Here is another example of a state government sticking its nose into something where it had absolutely no business at all.
