11180 Application Field and Working Principle

11180, also known as the National Standard, is a comprehensive system of electrical protective devices, installation methods, and circuit-testing procedures developed by the U.S. National Fire Protection Association. The system is based upon the underlying principles of fire safety, as detailed in NFPA standard 72. The 11180 system applies to all new or remodeled electrical systems and components in any type of building or facility, including homes, businesses, and factories.

Application Field

11180 is applicable to all electrical systems including residential, commercial, industrial, and institutional. It applies equally to any type of facility, including single-family dwellings, commercial buildings, hospitals, and multi-family dwellings.

The 11180 system is designed to protect people and property from electrical fires and shock hazards. It provides guidance on the selection and installation of circuit breakers, ground fault circuit interrupters, surge protectors, and other kinds of protective equipment. It also prescribes testing and maintenance procedures for these devices, as well as guidance on the proper installation of wiring and associated components.

Working Principle

The primary function of 11180 is to serve as a guide to ensure that electrical systems and components are properly installed and that appropriate safety measures are taken to protect people and property from electrical fires and shock hazards. In order to achieve this, it details a comprehensive set of standards for the selection, installation, testing, and maintenance of electrical protective devices, as well as specific requirements for the installation of wiring and associated components, such as junction boxes, conduit, and switches.

11180 is based upon the principles of electricity, such as proper grounding and bonding of components, the use of circuit breakers and other overcurrent protective devices, the installation of surge protectors, and the use of dual-pole switches. Additionally, it provides guidance on the selection and installation of Arc-Fault Circuit Interrupters (AFCIs) and Ground-Fault Circuit Interrupters (GFCIs).

The 11180 system is constantly evolving, and the NFPA updates it regularly in order to incorporate advances in technology and the latest safety research. It is the intention of the NFPA to make 11180 the most comprehensive and up-to-date safety system for electrical installations available.
