20 amp gfci circuit breakers: The Essentials
If you're a DIY enthusiast or an electrician, chances are you have heard of a ground fault circuit interrupter (GFCI). This device is designed to protect people from electric shock, and it is commonly used in homes and commercial buildings where water is present. A 20 amp GFCI circuit breaker is a type of circuit breaker that provides overcurrent protection and ground fault protection at the same time. In this article, we'll take a closer look at this device and its different aspects.
What is a 20 Amp GFCI Circuit Breaker?
A 20 amp GFCI circuit breaker is a two-pole circuit breaker that provides protection against electrical shock from ground faults. It combines the functions of a 20 amp circuit breaker and a GFCI device in one unit. When there is a fault, the GFCI component trips the breaker, immediately interrupting the circuit's flow and protecting individuals from any harmful electric shocks. The 20 amp rating indicates the maximum current that the circuit breaker can handle, which makes it suitable for household appliances, tools, and motors that require up to 20 amps of power.
How Does a 20 Amp GFCI Circuit Breaker Work?
A 20 amp GFCI circuit breaker works by constantly monitoring the current that flows through the circuit it protects. When the current flows out of the hot wire and returns to the neutral wire, the breaker creates a magnetic field. If there is an imbalance between the current flowing in the hot wire and the current returning in the neutral wire, which is an indication of a ground fault, the breaker immediately trips and cuts off the power supply to the circuit. This ensures that individuals do not get an electrocution from the circuit.
Where Should a 20 Amp GFCI Circuit Breaker Be Installed?
A 20 amp GFCI circuit breaker can be installed anywhere it is necessary to protect individuals from electric shock. It is typically used in outdoor circuits, wet locations, kitchens, bathrooms, and any area within six feet of a water source. Additionally, it should be installed to protect hard-wired appliances, such as dishwashers and disposals. If you are unsure of where to install a 20 amp GFCI circuit breaker, consult an electrician.
What are the Benefits of a 20 Amp GFCI Circuit Breaker?
A 20 amp GFCI circuit breaker provides several benefits, including:
- Protection against ground faults and electric shocks.
- Protection for outdoor circuits, which are more susceptible to different weather conditions.
- Easy installation and maintenance.
- Space-saving, as it combines the functions of a circuit breaker and GFCI device.
How to Install a 20 Amp GFCI Circuit Breaker?
Before installing a 20 amp GFCI circuit breaker, ensure that you have turned off the power supply to the circuit. You can then follow these steps:
- Remove the panel cover and disconnect the wires from the existing circuit breaker.
- Insert the new 20 amp GFCI circuit breaker into the panel, connecting the wires to the breaker.
- Push the breaker into place and ensure it is secure.
- Attach the panel cover.
- Turn the power back on and test the breaker.
How to Troubleshoot a 20 Amp GFCI Circuit Breaker?
If you are experiencing electrical problems or you find out that the 20 amp GFCI circuit breaker has tripped, follow these troubleshooting steps:
- Identify the source of the problem.
- Reset the breaker by switching it off and on.
- Check the outlets in the affected area to ensure that none of the receptacles are damaged or have loose connections.
- Test the breaker using its test button to make sure it is functioning properly.
- If you are unable to identify or solve the problem, consult an electrician.
What is the Price of a 20 Amp GFCI Circuit Breaker?
The price of a 20 amp GFCI circuit breaker depends on its type, manufacturer, and where you purchase it. Typically, you can expect to pay between $30 to $60 for a good quality 20 amp GFCI circuit breaker.
How Long Does a 20 Amp GFCI Circuit Breaker Last?
A 20 amp GFCI circuit breaker can last for many years, depending on how well it is maintained. Over time, the breaker may wear out, and you'll need to replace it. If you notice any signs of damage or the breaker frequently tripping, it might be time to replace it.
Conclusion
A 20 amp GFCI circuit breaker is an essential device in any home, business, or industry. It provides protection against ground faults and electric shocks, making it a valuable safety component. When installing a 20 amp GFCI circuit breaker, ensure that you follow proper installation methods and consult an electrician if necessary. Remember to test the breaker regularly and replace it when necessary to maintain optimum safety.
