Frequently Asked Questions (FAQs)

Q: Can I use any switch to control my light?

A: No, you need to use a switch that is compatible with your light fixture. A single-pole switch is suitable for controlling a single light fixture.

Q: How can I tell which wire is the power wire?

A: The power wire is usually black, and it is the wire that carries the electrical current. If you are not sure which wire is the power wire, turn off the power and use a voltage tester to test the wires.

Q: What is a wire nut, and how do I use it?

A: A wire nut is a cap-like device that is used to connect and insulate wires. To use it, twist the wires together and place the wire nut over the wires. Twist the wire nut clockwise until it is tight and secure.

Q: Can I wire multiple lights to a single switch?

A: Yes, you can wire multiple lights to a single switch using a special type of switch called a three-way switch. This switch allows you to control two or more lights from a single switch.

Q: Do I need to turn off the power before I change a light bulb?

A: No, you do not need to turn off the power to change a light bulb. However, it is always a good idea to turn off the power before any electrical work.
