The Installation of Electrical Isolated Receptacles

Electrical Ground

• Modern electrical systems use a ground connection to provide a backup safety system. If power gets somewhere it shouldn't, the ground wire gives that electricity a safe path back to the earth. This reduces the likelihood that someone will get electrocuted if there is a problem in the system. The ground connection is the green or bare wire in residential electrical systems. It is joined to all electrical boxes and most devices.

Ground Interferance

• Ground interference occurs when small currents travel along the grounding wires, interfering with sensitive equipment. Common occurrences in your home are a humming sound in home audio speakers or purple lines on your cable television. The solution is to isolate each device's ground connection with its own connection to the earth.

Electrical Isolated Receptacles

• Electrical ground isolation receptacles protect sensitive equipment from ground interference by strategically isolating themselves from the common ground. They accomplish this by having their own ground wire, which serves no other appliance, and travels directly to the ground. Second, they isolate themselves from the metal electrical box with insulation barriers and a nylon base. The combination of these two approaches effectively eliminates ground interference.

Electrical Wiring

• A building's electrical system uses three wires to make a single 120-volt circuit. The black hot wire sends the power to the device from the source. The neutral white wire provides the necessary path back to the electrical panel, and the green or bare wire acts as the ground. The gauge, or size, of the wire determines the amp amount it can safely carry.
