question about having your house re-wired. If the existing wires are
all snugly clamped to the framing, then how are theoldwires
removed? Does all the drywall have to come off, or would all theold
wiringbe disconnected from the main circuit box and just left alone
while new wires are fished thru?- Hide quoted text -

Yeah that hows its done run all newwiringand likely new breaker
box / service entrance.

Its a excellent thing to do adds safety, and convenience.

What you probably have is knob and tube wiring, which often causes
trouble getting homeowners insurance.

Although sadly it wouldnt save money on your electric bill

I appreciate your response,There is no knob & tube,but some areas has
2 white wires,and others have b&w ,my question is fire safety,Since
someone can read 120v between hot and ground,Now which white wire
suppose to be hot?

If there's two white wires instead of one black and one white, you can
determine which white wire is hot very easily by measuring from them to
a known ground somewhere else in the house. Alternatively, while
standing in a bathtub full of water, firmly grab each of the whites. The
one that kills you is hot.

Then you back up in time, mark that wire with a piece of black tape,
and don't touch it.

Or just put a label on the wall, "Don't touch the lethal wire."
