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.

Why Grounding Your Home is Important – Part 1

Within every electrical circuit there is an active wire that provides power and a neutral wire that returns the electrical current. A grounding wire can be connected to electrical devices and outlets then attached securely to the ground at the electrical panel. This grounding wire gives another outlet for electrical current to safely return to the ground without endangering people should a short circuit occur. In the even of a short circuit, current would flow through the ground wire and blow a fuse or trip a circuit breaker. Either result is better than an electrical shock that may cause injury or death.

How to Prevent Electrical Problems in Winter

Now that winter is coming, today is the perfect day to inspect your home’s electrical installations and prevent problems. Ensuring your home’s electrical wiring and that devices have proper maintenance is more critical during winter because power loss or an electrical fire are even more dangerous.

Compounding this problem is the increasing amount of electronic devices, which require more power. However, decades-old electrical circuits were not intended to cope with this growing demand. An older electrical system can be easily overloaded by utilizing power strips at several sockets. A licensed electrician can Improve safety and increase energy efficiency by adding extra sockets.

Electrical Devices

Electrical devices that see use mostly during the winter require extra attention when they are taken out of storage to be used again after several months. Beware of electric blankets that are worn and old because they pose a fire hazard. Inspect them before using and throw out any that have frayed edges. Another major fire risk is space heaters, and December and January are the most dangerous months. An extension cord should never be used on one. During the holiday season, festive lights are a common fire hazard. An estimated 390 fires are caused by Christmas trees or festival lighting annually. It is advisable to inspect them for frayed wiring or danger signs before using.

Electrical Safety Equipment

It is advisable that a home’s circuit breaker be inspected regularly by licensed electricians, especially before winter. A circuit breaker that was properly installed and maintained regularly is one of the most important methods to prevent electrical shocks and fires and electric shocks. Smoke alarms are another critical electrical safety measure, and they should be installed on every floor. It is recommended to use hardwired detectors, which use batteries as a backup power supply. Finally, the installation of surge protectors is recommended to protect computers and other electronic equipment.

Licensed  Electricians

If you have any doubts or concerns about your home’s wiring before the winter, it is best to consult with an experienced licensed electrician.
