What does GFI mean in AIRCRAFT & AVIATION

Ground Fault Interrupter (GFI) is a type of circuit breaker designed to protect people from electrocution caused by electrical faults. It works by detecting any disturbance or imbalance in the amount of current flowing between a hot wire and its grounding wire and immediately cutting off the circuit.

The use of Ground Fault Interrupter (GFI) provides an additional layer of protection against electrical hazards, thereby increasing safety for personnel working with electricity. It also helps prevent damage to electrical appliances due to power surges or voltage drops.

GFIs are typically installed in areas where moisture or dampness could cause an electric shock, such as kitchens, bathrooms, garages, outdoors locations, basements, etc. They should also be installed near wet locations such as swimming pools and spas so that any accidental shocks can be minimized.

Generally speaking, GFIs must be tested every three months to ensure they are functioning correctly. Testing should also take place after any repairs or replacements have been made and after any major storm events that may affect power supply or demand on circuits.

Although it's possible for someone with basic knowledge and experience in working with electricity to install GFI units safely, it's generally best to hire a professional electrician who has expertise in both installation and maintenance work on these devices. This will ensure that all wiring connections remain safe over time and that your home's wiring meets national safety standards.
