Why Electrical Codes are Necessary for Home Electrical Wiring

Introduction to Basic Electrical Codes

Why we need electrical codes

Ever since electricity was discovered and installed across our nation safety became a very important factor to help reduce the hazards that were involved when installing and using electrical systems and circuits.

With the development of several new systems and modern conveniences which operated on electrical power electrical codes were developed and enforced to ensure safety for the home electrical wiring and for those who used these appliances and equipment.


The National Electrical Code is adopted and enforced to ensure that the home electrical systems are installed safely to avoid the risk of fire or other damage that may result from unsafe electrical wiring practices.

Electrical codes as they apply to house wiring include methods that involve circuits that are used for all aspects of the distribution of electricity which will be used for various devices and systems which may be automatically or manually operated.

Electrical systems that are installed require specific locations and the ability to access the electrical components so that devices and services may be connected to or used safely.

The space where electrical equipment, services and panels are installed must maintain a specified amount of space to allow access for servicing or maintenance.

Exposure to weather elements are also a factor where electrical codes must be maintained to assure a safe enclosure for the electrical item and safe use of the device or equipment.

GFCI or Ground Fault Circuit Interruption circuits or devices are required in specific locations where exposure to grounded surfaces may result in an electric shock while operating an electrical device or equipment.

AFCI or Arc Fault Circuit Interruption circuits or devices are required in specific locations of the home to reduce the risk or arcing within an electrical circuit or a device that is connected to an electrical circuit.

The Development of Home Electrical Codes

Home electrical codes have been developed for several years thereby making the installation and use of electricity much safer in every aspect of our lives.

As we become more dependant on the various electrical systems and devices that we rely on new electrical codes will be written and enforced to increase safety during our exposure to electricity.
