Just for your Info. Everything from Sheep Creek east is controlled by a power regulator, on the pole ,a block from the bottom of Sheep Creek. All of that voltage is notoriously low when there is demand. This is due to too small of wire size, hanging in the poles, going through out the far east side of town. I have had to deal with this problem for years and they won't correct it until Pacific Crest builds out. They have to guarantee , in California, 116-120volts before demand. Edison sets the voltage down to around 117 or the demand on this section of wire would burn up on the poles. Happened in front of my house and shut down the whole neighborhood this spring/summer. Very hard on your appliances and circuit boards. Makes everything increase amperage, to compensate ,and the circuits,motors relays etc. get too hot. Edison is very aware of this problem.
In the main section of town ,most everything is off of the Hwy 2 station and should be auto regulated. Anytime a certain section of town raises voltage, it can be a major issue , if only a block or two goes higher it is usually at a pole. Not good for your appliances either as it is not about the gradual heat factor ,it is about whether the potential voltage will burn out the undersize wiring in step-down transformers, that are designed for 117-120volts. Keep on them, as there is a lot of fire danger hanging up in those wires and what they supply on the desks of your homes.
