Does white wire go to gold or silver?

Power comes from the service panel along the black (hot) wire through other outlets, switches and light fixtures on the circuit and begins its return to the source through the white (neutral) wire. The black wire attaches to a brass terminal; the white wire, to a silver terminal.

Where does the black wire go on a plug?

Connect the black hot wire or black pigtail to one of the brass (hot) screw terminals on the receptacle. For standard outlet wiring, the white neutral wire can go on either of the two silver terminals, since they are interchangeable. Likewise, the black hot wire can go on either brass screw terminal.

Is silver gold or neutral?

The neutral line on the lamp cord is the one that's odd; it'll have ribbing, a sharp ridge or printing on it. If the cord is translucent, the neutral is silver. The wire that goes to the narrower prong has a smooth, plain surface or is gold in color.

Why is my white wire hot?

Here’s a rundown of electrical wires: The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.

How can you tell if wire is aluminum?

You can tell if you have aluminum wire in your home by checking your electrical panel or looking at cables running through the basement or attic. The cables may be marked AL, ALUM or ALUMINUM, indicating aluminum wire.

Does a light switch need a neutral?

Switches don’t get neutrals, they only want 2 wires: hot and switched-hot. Unless you’re dealing with a smartswitch, those take neutrals but there is still a switched hot to account for. And red is a common switched-hot color, but it would never, ever, ever, ever be used for neutral.
