What to do when you have 2 black wires?
STEP 3: Identify the terminal and ground wires.
Observe the layout of the wires. You should see two black wires, each connecting to a different screw on the side of the switch. These are called terminal screws. You will also see two white (neutral) wires that connect to one another in the box.
What is yellow electrical wire used for?

What does a black and yellow wire mean?
Black wires are hot wires that run to the electrical outlet from the switch. Red wires are hot wires common in a 240-volt outlet or when a wall switch controls the outlet.

How do you wire a light switch with two black wires?
Connect the top screw to the wire that feeds to the light. Connect the bottom screw to the hot wire. When you turn the power back on, and if you want to swap the direction of the switch (as in press down to turn off, or turn on), turn off the power and switch the two black wires.
Which wire is hot if both are black?
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 do you wire a ceiling light?

What is yellow Romex used for?
Yellow Wire
The heavier, yellow ROMEX® is rated at 20 amps. Common applications for this 12-gauge wire are receptacles and three-way circuits. Larger appliances, such as a microwave or welder, require the additional power this wire delivers.
What is the difference between white and yellow electrical wire?

Copper or green wire is the ground wire and keeps the fan from experience power surges. If there is a blue and black wire coming from the household circuit, there should be two switches on the wall.
What happens if you wire a ceiling fan backwards?
Wiring the fixture incorrectly could lead to circuit breakers tripping, lights burning out quickly, or a ceiling fan turning in the wrong direction. Fortunately, this is something any homeowner can do with an inexpensive voltage tester.
