sec.247 Performance and other requirements for works

The following requirements apply for the works of an electricity entity— the works must be able to perform under the service conditions and the physical environment in which the works operate; the works must have enough thermal capacity to pass the electrical load for which the works are designed, without reduction of electrical or mechanical properties to a level below that at which safe operational performance can be provided; to the greatest practicable extent, the works must have enough capacity to pass short circuit currents to allow protective devices to operate correctly; the works must have enough mechanical strength to withstand anticipated mechanical stresses caused by environmental, construction or service conditions; the works must be— designed and constructed to restrict unauthorised access by a person to live exposed parts; and operated in a way that restricts unauthorised access by a person to live exposed parts; records about the design, construction, operation and maintenance, and testing and inspection of the works that are necessary for the electrical safety of the works must be kept in an accessible form; parts of the works whose identity or purpose is not obvious must be clearly identified by labels, and the labels must be updated as soon as possible after any change is made to the works; electrical equipment intended to form part of the works must undergo commissioning tests and inspection to verify the electrical equipment is suitable for service and can be operated safely when initially installed or altered.

• (a) the works must be able to perform under the service conditions and the physical environment in which the works operate;
• (b) the works must have enough thermal capacity to pass the electrical load for which the works are designed, without reduction of electrical or mechanical properties to a level below that at which safe operational performance can be provided;
• (c) to the greatest practicable extent, the works must have enough capacity to pass short circuit currents to allow protective devices to operate correctly;
• (d) the works must have enough mechanical strength to withstand anticipated mechanical stresses caused by environmental, construction or service conditions;
• (e) the works must be— (i) designed and constructed to restrict unauthorised access by a person to live exposed parts; and (ii) operated in a way that restricts unauthorised access by a person to live exposed parts;
• (i) designed and constructed to restrict unauthorised access by a person to live exposed parts; and
• (ii) operated in a way that restricts unauthorised access by a person to live exposed parts;
• (f) records about the design, construction, operation and maintenance, and testing and inspection of the works that are necessary for the electrical safety of the works must be kept in an accessible form;
