PART III SWITCHES, CONDUCTORS AND ELECTRIC MOTORS
7. Every switch, switch fuse, circuit breaker and isolating link shall be--
(a) constructed, placed and protected so as to prevent electrical hazard;
(b) constructed and adjusted accurately so as to make and maintain effectual contact;
(c) provided with a handle or other suitable means of working, insulated from the system and arranged so that the person operating it is unlikely to make accidental contact with live metal;
(d) constructed and installed in such manner so that when in an "off" position it cannot accidentally make contact with live metal;
(e) constructed and installed in such manner so that it cannot with proper care be left in partial contact with live metal; and
(f) constructed and installed in such manner as may be necessary to prevent electrical hazard from arcing and so that an arc cannot accidentally be maintained.
8. (1) Every circuit shall be protected against excess current and energy by means of a suitable fuse or circuit breaker of adequate breaking capacity suitably located and of such construction as to prevent electrical hazard from overheating, arcing, or the scattering of hot metal or other substance when it comes into operation.
(2) Every fuse and circuit breaker shall be capable of breaking the maximum prospective excess current or energy at the point of installation and every switch intended to be used for breaking under load shall be capable of breaking the load at the point of installation without causing electrical hazard.
(3) Every fuse shall be either constructed and installed in such manner or protected by a suitable switch so as to permit the ready renewal of the fuse element without electrical hazard.
