An electrical code is a term for a set of regulations for the design and installation of electrical wiring in a building. The intention of such regulations is to provide standards to ensure electrical wiring systems are safe for people and property, protecting them from electrical shock and fire hazards.
For low-voltage distribution circuit breakers an international standard, IEC 60898-1, defines rated current as the maximum current that a breaker is designed to carry continuously. The commonly available preferred values for rated current are 1 A, 2 A, 4 A, 6 A, 10 A, 13 A, 16 A, 20 A, 25 A, 32 A, 40 A, 50 A, 63 A, 80 A, 100 A, [ 6 ] and 125 A.
The International Electrotechnical Commission (IEC; French: Commission électrotechnique internationale) is an international standards organization [3] [4] that prepares and publishes international standards for all electrical, electronic and related technologies – collectively known as "electrotechnology".
