Electrical – have low voltage and backfeeding between circuits throughout the whole house

electricallow-voltage

If I plug a hairdryer or anything else into a outlet, I lose voltage in the whole house. If I plug the iron in, the stove surges. This is a nightmare. I can't run the fridge; I can't even get the TV to come on. This just happened all of a sudden.

Also I have backfeeding on multiple circuits. No breakers have tripped. On my main breaker I'm pulling 170V with nothing on. Also I can shut all circuits down and still loose voltage on that circuit.

What could be happening?

Very very dangerous. First, all your electrical equipment is at risk. Shut off the mains, call an electrician. Or wait a bit longer and call the fire brigade.

If you have a shared neutral, or multiwire branch circuit, the neutral could have broken. Or the house was miswired (see http://www.homeinspector.org/resources/journals/Multiwire-Branch-Circuits.pdf ). Or what should have been a double breaker flipped, leaving the other half hot.
