Home Care Guide: Electrical Service Entrance
The electrical wiring and equipment in Homes is protected by circuit breakers. They are the safety valves of your home’s electrical system. The electrical service entrance, which provides power to the service panel, has been designed for the electrical needs of your home. Do not tamper with this cable. Every home has a master circuit breaker located in the service panel box along with smaller circuit breakers. When the master breaker is tripped the electricity in your home is cut off. Circuit breakers may be reset by first switching the breaker to FULL OFF and then back to FULL ON.
Your air conditioning unit may have heavy duty cartridge fuses or some other disconnect mechanism located in a small box next to the service panel or next to the unit. These may be replaced by simply pulling them from their retaining clips and installing a new cartridge. BE CERTAIN TO TURN OFF POWER BEFORE REMOVING CARTRIDGES.
