Few things are more important than grounding when it comes to electrical safety. Ground faults allow current to flow through any number of electrical paths, creating electric shock and fire. Grounding, however, forces excess voltage to flow through a specific path and into the ground. This system protects against abnormal current flow and circuit interruptions.
At Carbone Plumbing in Milwaukie, OR, we help homeowners install and maintain their grounding systems for their electrical systems. Ground fault protection is paramount for anyone in any indoor space, including residential, commercial, and industrial settings. Let’s explore electrical safety and how grounding protects you and your home.
What is Ground Fault Protection?
Ground fault protection is a critical safety measure designed to detect abnormal or excess electrical currents and prevent hazardous situations by rerouting the current into the ground. Monitoring the flow of electricity in your electrical system’s circuits is the way the device works. If a ground fault, such as a short circuit or electrical leakage, is detected, the protection device automatically interrupts the circuit’s power supply.
Ground fault protection dramatically reduces the risk of fire, equipment damage, and electric shock. Most ground fault protection systems use RCDs (residual current devices) or GFCIs (ground fault circuit interrupting devices). These devices are placed in circuit breaker panels or electrical outlets.
Understanding Ground Faults and Their Dangers
A ground fault occurs when an unintended pathway forms between an electrical current and the ground. This often happens because of faulty wiring, poor insulation, or poor initial installation. Ground faults are particularly dangerous in wet environments, where there is a greater risk of electrical shock. You need to be able to recognize the signs of ground faults, such as tripped GFCI outlets, tripped circuit breakers, or fried electrical outlets. These issues must be addressed to prevent a dangerous situation, such as a fire or electrical shock, from occurring.
How Ground Fault Protection Works
Ground fault protection works by constantly monitoring the electrical flow within the circuit. The system compares the current that enters the circuit with the current that returns from the circuit, which is also called the neutral current. If there is a difference between the current, it tells the system that some of the current is flowing through an accidental current. Ground fault protection devices interrupt the circuit and stop the current flow in these cases. These devices can respond within milliseconds, so they offer immense protection.
Types of Ground Fault Protection Devices
Several types of ground fault protection devices are available. The best choice for your home or office building depends on the structure and current electrical system. Residual Current Devices are most often used in homes or workplaces. They detect current imbalances, and if they notice a ground fault, they will trip the circuit.
Ground Fault Circuit Interrupters, however, are designed for a single outlet and are most often used in places like bathrooms or kitchens. They focus on a single outlet and tend to be in areas where excess voltage would be catastrophic.
Arc Fault Circuit Interrupters are another type of circuit that works to stop arcing faults. Arcing faults create sparks between conductors. These are most commonly used in places with higher electrical fire risk, such as living rooms, bedrooms, and kitchens. It can be daunting to decipher which type of ground fault protection device should be used in your home or office space. At Carbone Plumbing, we are well-versed in these devices and can help you make the best choice for you and your property.
Ground Fault Protection Requirements by Code
Different states and cities feature different electrical code mandates. However, most require the installation of ground fault protection devices in some or all rooms of the home. Ignoring these codes can jeopardize your health, your loved ones’ health, and your property and get you into legal trouble. Codes often require the installment of GFPDs in garages, outdoor areas, kitchens, and bathrooms due to potential water exposure and proximity to grounded surfaces.
Codes will also state what the trip thresholds and sensitivity thresholds have to be in each area. When we install and maintain electrical systems for our customers, we always make sure that we follow all codes and regulations for ground fault protection.
Installation and Maintenance of Ground Fault Protection Systems
Installation of ground fault protection systems involves several vital steps to make sure that they are compliant with electrical codes and will function properly. Qualified electricians are the only people who should install ground fault protection systems.
First, these electricians will choose the best ground fault protection device based on the electrical code requirements, the installation location, and the electrical load needs. They will install the GFPD device and ensure that the wiring connections are properly set. Then, they will test the GFPD to make sure that it was installed correctly and is working properly. Electricians will also conduct periodic inspections to check for any signs of damage, wear and tear, or malfunction in the GFPD and the electrical wiring throughout the property.
When we install ground fault protection systems for our clients, we take a comprehensive approach. We want to ensure that you have the best device type and installation method for your property and strongly encourage working with licensed electricians and contractors who understand your property and are committed to finding the best solution for you. Electrical systems are not one-size-fits-all.
Testing Ground Fault Protection Devices
Testing ground fault protection devices help maintain functionality and make sure that the devices are operating at high efficiency. Regular testing will help find faults in the devices that can be repaired or replaced before a catastrophic event. One of the most common tests is to use a push-to-test button, which simulates a ground fault condition and checks to see how the device responds.
If the device fails to properly divert the excess current, then a repair or replacement can be made. We recommend regular testing with a professional contracting company that has licensed electricians on their team. Incorporating testing protocols will help keep your property safe and limit the risk of electrical hazards caused by ground faults.
