When it comes to home electrical systems, one of the most crucial components is the light switch. Light switches allow us to control the flow of electricity and turn lights on and off with ease. A 20 amp light switch is a type of switch that can handle up to 20 amps of electrical current, making it ideal for use with high-powered lighting fixtures or appliances.
What is a 20 Amp Light Switch?
A 20 amp light switch is a type of single pole switch that is designed to handle up to 20 amps of electrical current. This type of switch is typically used in areas where higher voltage is required, such as in commercial or industrial settings where high-powered lighting fixtures or appliances are being used.
Most residential homes use 15 amp light switches, but if you have a large home or are using high-powered devices, a 20 amp switch can be a better option. It is important to note that all wiring and electrical components connected to a 20 amp switch must also be rated for 20 amps or higher.
Wiring a 20 Amp Light Switch
Wiring a 20 amp light switch is similar to wiring a 15 amp switch, but there are a few differences to keep in mind. Here’s a step-by-step guide:
- Turn off the power to the circuit you will be working on by flipping the corresponding circuit breaker in your electrical panel.
- Remove the switch plate cover and unscrew the switch from the electrical box.
- Attach the black or red wire (the “hot” wire) to the brass screw on the switch. This is typically the top screw, but check the manufacturer’s instructions to be sure.
- Attach the white wire (the neutral wire) to the silver screw on the switch. This is typically the bottom screw, but again, check the manufacturer’s instructions to be sure.
- Attach the bare copper wire (the ground wire) to the green screw on the switch.
- Carefully tuck the wires back into the electrical box, making sure not to pinch or damage any wires.
- Screw the switch back into the electrical box and replace the switch plate cover.
- Turn the power back on at the circuit breaker, and test the switch to make sure it is working properly.

FAQ
What is the difference between a 15 amp and 20 amp light switch?
The main difference between a 15 amp and 20 amp light switch is the amount of electrical current they can handle. A 15 amp switch is designed to handle up to 15 amps of current, while a 20 amp switch can handle up to 20 amps. If you have high-powered lighting fixtures or appliances that require more current, a 20 amp switch may be a better option.
Can you use a 20 amp switch on a 15 amp circuit?
No, you should not use a 20 amp switch on a 15 amp circuit. All wiring and electrical components in a circuit should be rated for the same amperage, so using a 20 amp switch on a 15 amp circuit could create a fire hazard or cause other electrical issues. Stick with a 15 amp switch for 15 amp circuits.
Can you replace a 15 amp switch with a 20 amp switch?
Yes, you can replace a 15 amp switch with a 20 amp switch, but you will also need to replace any wiring and electrical components connected to the switch with 20 amp-rated components. This includes the wiring, the electrical box, and any light fixtures or appliances connected to the switch. If you are unsure how to do this, it is best to hire a licensed electrician.
What is the cost to install a 20 amp light switch?
The cost to install a 20 amp light switch can vary depending on a number of factors, including the location of the switch, the amount of wiring required, and whether or not any additional electrical work is needed. On average, you can expect to pay between $150 and $300 for a licensed electrician to install a 20 amp light switch.
Do I need a permit to install a 20 amp light switch?
In most cases, you will need a permit to install a 20 amp light switch. Electrical work can be dangerous, and permits help ensure that the work is done safely and up to code. Additionally, failing to obtain the proper permits can result in fines or other penalties. Check with your local building department to find out what permits are required in your area.
Installing a 20 amp light switch can be a great way to ensure that you have enough electrical power to handle high-powered lighting fixtures or appliances. Just make sure to follow proper wiring procedures and use the right components to ensure that your system is safe and up to code.
