wire burnt in my electrical outlet, what's the cause for "white wire" burn?

Answer 1

Since breaker did not trip it was probably a loose connection(was it in the friction hole on the outlet?Should have been under the screw) causing it to arc.

Answer 2

For the most part, burned wires attached to a wall recept are the result of overloading the recept at some point. If the breaker didn't trip or a fuse didn't blow, then the load was less than the circuit will hold, but more than the recept was designed for. If you're moderately handy and can run a screwdriver, plug a lite of some sort into the recept, so that you can see it from the breaker, fuse box, and turn off the electric to that circuit. If you plan on using that recept for the same appliance again, then get a hospital grade recept., (probably the same amp rating as the circuit breaker/fuse used to hold the circuit, if not, then get a standard amp rated recept and replace it taking one wire off at a time and replacing it back on the corresponding screw of the new recept.

Answer 3

In house wiring, White is the common, (works like the ground in a DC circuit. Your house is AC). Sounds to me like too much current was drawn or is being drawn through that outlet. Thin down the amount of items plugged into it. Yes you will need an electrician to fix that. Might be quite expensive to do that too.

Answer 4

It shorted out or overheated because something drew too much power. You need a qualified electrician to check you wiring and fusebox to make certain everything is OK, unless you want your house to burn down.

Answer 5

Usually its a loose connection.make sure that all the connetions are secure.
