[接上页] (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. Cap 59W reg 8 Protection of circuits by fuses and circuit breakers (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. Cap 59W reg 9 Construction of joints and connexions Every electrical joint and connexion shall be of proper construction and design as regards conductivity, insulation, mechanical strength and protection. Cap 59W reg 10 Isolation of voltage from parts of a system Such efficient means, suitably located, shall be provided for cutting off and isolating all voltage from every part of a system as may be necessary to prevent electrical hazard. Cap 59W reg 11 Use of single-pole switches with one conductor earthed In a system where one of the conductors is connected to earth, no single-pole switch shall be placed in that conductor or any branch thereof, other than a link for testing purposes or a switch for use in controlling a generator. Cap 59W reg 12 Means of isolating voltage in special circumstances (1) Subject to paragraph (2), such efficient means, suitably located, shall be provided for cutting off and isolating all voltage from every motor, converter and transformer forming part of a system and all apparatus used in or in connexion therewith. (2) It shall not be necessary to comply with paragraph (1) in the case of a conductor in a system if that conductor is earthed. Cap 59W reg 13 Starting and stopping of electric motors (1) Every electric motor shall be controlled by an effective switch or switches for starting and stopping, and the switch or switches shall be so placed as to be readily accessible to and easily operated by the person in charge of the motor. (2) Where a machine is used and driven by an electric motor, such efficient means, suitably located, shall be provided for either stopping the machine or switching off the electric motor as may be necessary to prevent electrical hazard or other danger. (3) Every electric motor shall be equipped with such efficient means so that when stoppage occurs by reason of a fluctuation in voltage or failure in supply of electricity the motor will not restart automatically in circumstances whereby unexpected restarting is likely to cause electrical hazard or other danger. Cap 59W reg 14 Connexion and earthing of portable apparatus exceeding extra low voltage Portable apparatus operating at a voltage exceeding extra low voltage shall- (a) have all its flexible wires connected to the system either by effective permanent joints or by properly constructed connectors; (b) be protected against leakage to earth of current liable to cause electrical hazard; (c) be controlled by efficient means suitably located so as to permit ready operation for cutting off all voltage. Cap 59W reg 15 Construction of switchboards PART IV SWITCHBOARDS AND SWITCHBOARD APPARATUS Every switchboard shall be constructed and installed so that so far as is reasonably practicable- (71 of 1989 s. 13) (a) adequate access can be obtained to any component part which may have to be adjusted or handled; (b) the location, course and continuity of every conductor may where necessary be readily identified and traced; (c) every conductor arranged for connexion to a separate system is located and kept apart and may where necessary be readily distinguished; and (d) every bare conductor is protected against accidental short circuit liable to cause electrical hazard. Cap 59W reg 16 Enclosure of bare conductors on switchboards (1) Subject to paragraph (2) every switchboard having a bare conductor liable to become live and normally exposed so that it is possible for a person to make accidental contact with live metal shall be adequately enclosed or fenced so as to prevent electrical hazard. (2) Paragraph (1) shall not apply in the case of a switchboard having a bare conductor installed to serve any particular purpose of the industrial undertaking and so situated as to be accessible only to an authorized person or a competent person acting under the immediate supervision of an authorized person. |
