Standardized electrical codes from the NEC (National Electrical Code) are for the safety of homeowners and their families. We’ll discuss typical codes applicable for new homes and remodels that will increase safety in older homes. Talk to a reputable and licensed electrician near you about complying with local codes.
More than one circuit is required because people will often have several items running simultaneously. A common set of heater, light, and fan should be equipped with an individual 20-amp circuit. An appliance like a hair dryer will require its own 20-amp circuit. A GFCI (Ground Fault Circuit Interrupter) for each circuit is a must for safety because water is present.
Bedrooms, Living & Dining Rooms
Every room should have a wall switch next to its door to let people turn the light on before entering. Ceiling fixtures should be operated by a wall switch, rather than a pull chain that may detach or break. Wall receptacles will require installation within 12 feet of each other. A dedicated 20-amp circuit may be required to provide power to a window air conditioner, microwave, or entertainment center.
Every closet will require a covered light fixture controlled by a wall switch. Dated fixtures with exposed bulbs are hazardous.
At least one wall switch should operate a ceiling light, independent from the garage door opener light. A separate circuit should be installed, along with a minimum of one GFCI wall outlet. Exterior outlets require GFCI protection.
Hallway and Stairway
At each end of a hallway or stairway, a 3-way switch is required. Hallways longer than 10 feet should have a general purpose wall outlet. Full lighting is required for stairways for safety. Landings and turns may require additional lighting.
Every major appliance, including the dishwasher, refrigerator, microwave, and garbage disposal will require a dedicated 240-volt circuit. Above the countertop, there should be a minimum of two circuits with outlets.
The washer and gas dryer will require their own 20-amp circuit. A separate 240-volt circuit will be needed for an electric dryer.
