Black wire goes to brass colored terminal, white wire goes to silver colored terminal and bare wire goes to green colored screw.
Do not remove any electrical plug by grabbing the wire. This weakens the connection at the plug. ALWAYS grab the plug itself when removing it.
Electrical energy comes out of a wall socket.
The hot wire's cover is smooth and connected to what I call the "button" at the bottom of the socket. The neutral wire's cover has ridges and is connected to the screw shell of the socket.
An outlet will only get hot enough to cause a fire if:There is a problem with the wiring connecting it to the supply, this will become quickly obvious when in use.It is overloaded. The electrical supply is supposed to have a fuse or breaker to prevent this.There is also a 3rd cause of potential fire:3. A loose wall socket connectionLoose wall socket connections can be a MAJOR concern, causing the plug and socket to overheat. This is primarily a problem on older homes.
In a household circuit, with a "hot" conductor insulated black and a white neutral, the black wire should connect to the center terminal of the socket. The outside part of the socket usually has a brass screw (for the black wire) and a nickel screw (for the white wire).
