GFCIs or ground fault circuit interrupters, significantly decrease the chances of shock by instantly shutting down an electrical circuit when it represents a shock hazard. The information below summarizes the updated GFCI requirements of the NEC (National Electrical Code) 2017 edition. For safety and the best results, rely on an experienced and licensed electrician

Typical Home Electrical Codes for Safety

Standardized electrical codes from the NEC (National Electrical Code) are for the safety of homeowners and their families. We’ll discuss the typical codes applicable for new homes and remodels and those that would increase safety in older homes. Discuss how to comply with local codes as well with an experienced and licensed electrician.


More than one circuit is required because people will often have several items running simultaneously. A combination heater, light, and fan should be equipped with an individual 20-amp circuit. An appliance like a hair dryer will also require its own 20-amp circuit. A GFCI (Ground Fault Circuit Interrupter) for each circuit will be necessary for safety because of the presence of water.


Every closet will require a covered light fixture controlled by a wall switch. Dated fixtures with exposed bulbs are hazardous.

Garage (Attached)

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.

Laundry Room

The washer and dryer will require their own 20-amp circuit. A separate 240-volt circuit will be needed for an electric dryer.

Living, Dining, and Bed Room

Every room should have a wall switch next to its door to let people turn on the light when 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.

Does Your Home Need a Heavy-Up?

You might need a heavy-up if your home was built more than 30 years ago. Basically, a heavy-up will raise amperage entering the home through its electrical service panel to allow its system to manage a greater load. Some older homes will also need an electrical system upgrade to meet modern demands. When older homes were constructed, many devices did not yet exist, appliances were smaller, and homes consumed much less electricity.
