Go to your main fuse box or circuit breaker panel with a battery-operated AM radio tuned between stations. Bring a flashlight if the box or panel is in a dark or enclosed area. Make sure the panel is in safe condition and keep the radio antenna away from any exposed conductors. 

Listen for interference on the radio. When you hear the interference on your radio, interrupt power to your home by turning off the main circuit breaker. Do not remove fuses and leave their holders exposed. 

If you continue to hear interference, the source could be in a neighboring home or building. Restore the main breaker and all other sub-breakers to "on." 

For further assistance locating the source of the interference, please call SCE at 1-800-655-4555. 

If the interference stopped when you shut off the main circuit breaker, try to locate the source of the interference in your home. With your AM radio tuned between stations, turn the main circuit breaker back on. After the interference returns, turn the circuit breakers off one at a time until the noise stops. Now turn on all the breakers except the one that stopped the noise. 

Because the source of the interference is on the circuit you turned off, check your outlets, doorbell, lights, clocks, other appliances or electrical equipment without power. 

Once you've located and removed the interfering device, your radio and television reception will return to normal.

Most interference is caused by household equipment or a neighbor's appliances and tests in most areas have shown little or no interference from SCE power lines. If your appliances are causing the RTVI, they may be affecting your neighbors' radios and televisions as well. 

RTVI may be caused by common household appliances such as heating pads, a faulty doorbell transformer, tropical fish tank heaters and pumps, baby wipe warmers, touch lamps, dimmer switches and home lighting photocell switches.

Safety on the job is critical and can be lifesaving, especially for those who work near electrical equipment. Call SCE at 1-800-611-1911 to verify voltages and determine required safety clearances. Always keep people and equipment at least six feet away, and cranes and similar equipment at least 10 feet away from both overhead power lines and electrical facilities while working. Higher voltages require greater clearance distance.
