|An electrical circuit protected against fire.|
Protected circuits are required where it is critical that an electrical circuit continues to operate during a fire. This should include the use of sufficiently robust cables, careful selection of cable routes, and / or by the provision of physical protection in areas where cables may be susceptible to damage. Cable supports should generally be non-combustible and such that circuit integrity will not be reduced below that afforded by the cable.
Protected circuits should be separate from other circuits.
