Sometime during the middle of the night I loose power to
Sometime during the middle of the night I loose power to part of my house while we are sleeping. I wake up to flashing alarm clocks in back bedrooms and flashing oven clock at other end in kitchen. No breakers have been tripped and seems to shut off and then turn back on by itself. My wife said it has possibly happened atleast 5 times in one night. I do notice kitchen lights flicker once in awhile.

A house recieved a power surge of 440 volts.It blew 2 x voltage stabalisers and damaged a TV, radio and microwave.The house may not be properly earthed.1. If the house was properly earthed, would the 440 volt surge still have damaged the appliances or would the earthing protect the appliances against a 440volt surge.We have 240volt.The house is 3 phase

I have trailers hooked up from my main cabin breaker box,
i have trailers hooked up from my main cabin breaker box, about 100 ft to the breaker box for my trailer (modular office bldg). because of the distance there are a few splices that go under the trailer. if the bare wires are touching the ground (desert sand) would it be drawing power into the ground? Also what happens if they get wet? its actually the same wire we used that connects the power from the pole to the house , aluminum. its the only wire we could find that would make the distance to the back of the 60 foot trailers where the breaker box is located.everything works and has been working but i just wonder about the cost, my bill has been quite high and i also have just had a quick power surge but without blowing a breaker. I also am living in these trailers while my cabin is being renovated.
I plugged in what turned to be a faulty Christmas decoration
I plugged in what turned to be a faulty Christmas decoration into an outlet. I sensed a power surge and half the circuit went dead. I found an attic junction where three wires come together and found that the wire nuts had melted. I cleaned and reconnected the wies but still have no power. Changed original outlet. Still no power. Any thoughts?

There is a product called "Black Hawk Powerhouse." It suppo
There is a product called "Black Hawk Powerhouse." It supposedly can cut power consumption up to 30% for business. I have watched everything on line and it 'appears' that the demonstrations show that it cuts power usage. However I have read some of the blogs where some Electricians say it is just a big, very expensive, power surge protector.I was introduced to the product one year ago. I figured in a year I would see all kinds of complaints about it online but I have not found that to be true. Of course I want to save power but many power savers tend to be scams.
I ran a sub panel 250 feet from my 200 Amp main using a 3 wireView more electrical questions
I ran a sub panel 250 feet from my 200 Amp main using a 3 wire aluminum 3/0 wire. I have a 60 amp 240 volt heat pump plus lights, electrical outlet for tools and etc (including a 120 V compressor etc). Initially the wire is ran in a metal conduit (about 30 feet) before I bury it in the ground. The wire is direct bury rated. Now when the heat pump turns on I hear a momentary buzz (less than a second) within the metal conduit (not at the main panel) and while the pump is running I hear a small hum in the conduit until the pump turns off. The grounds and neutral are bonded at the sub panel. Reading, I probably should have run a 4 wire with separate ground and neutral, but what would be the best option now? If I need to run a 4 wire direct bury cable, what type and size should I do?
