If necessary, run a new circuit to serve the need of all your appliances. Disperse the load by plugging some of the appliances involved into another circuit. If all appliances are in good working order and the circuit breaker continues to trip, there are too many appliances, lamps. Repair any damage found before plugging the load back into the circuit. Also, look for broken light sockets or other damage that may be causing the device to short when plugged in. Note: Before reconnecting each load, check for frayed cords or a damaged plug on appliances or lamps. With the breaker on, reconnect each load, one at a time, until you determine which load is causing the problem. If the breaker doesn't trip, then one of the loads normally connected to the circuit likely has a short or is causing an overload. Retest the breaker after repairs are completed. Check the wiring to find the fault and repair or replace any cable or devices involved. If the breaker trips with all loads removed, then you probably have a short somewhere in the house wiring. and make sure all other lights are off or the bulbs are removed. To find the cause, remove all loads from the circuit. What many RV owners discover after they buy an RV or trailer, is that they cannot plug it in when they are at home. If a circuit breaker trips, the cause is likely either a short circuit or an overload.

These are also required in hospitals where sensitive medical monitors may be affected by grounding noise in the wiring which can cause disruption in their critical functions. This arrangement is used for computers and sensitive A/V equipment such as a home theater to eliminate noise interference in the audio and video output that can be caused by the random electrical activity on the grounding wires throughout a dwelling's electrical system. When connecting the wires, the isolated ground wire (the red wire pictured here) is marked with green tape or paint on each end and connected to the grounding bar in the service panel and to the grounding terminal on the receptacle. The receptacle can be identified by the orange color and a small triangle imprinted on the face. The bare copper ground wire is NOT connected to the receptacle, instead it is connected to the grounding terminal inside the metal outlet box where the receptacle is housed.Ī special isolated-ground receptacle is require for this circuit and is connected to a standard circuit breaker. The other cable wires are connected as with any other branch circuit except for the ground wire. It is connected to the grounding terminal on the receptacle and the ground bar in the breaker box. In a 15 amp circuit, the red wire in a 14/3 cable is used for this purpose and marked green at both ends. Wiring for a 15 Amp Isolated Ground CircuitĪn isolated-ground receptacle makes use of an extra wire to provide a separate, dedicated ground in the circuit.
