Common use of Fusing and testing facilities Clause in Contracts

Fusing and testing facilities. Where current and/or voltage transformers are used, testing facilities shall be provided close by the Meters of each circuit which enable such Meters to be routinely tested and/or changed safely with the circuit energised. (See Appendix C.) Separate fusing shall be provided locally for:- 5.2.1 the Meter; 5.2.2 any other Metering Equipment burden for Allocation purposes; and 5.2.3 any other equipment burden e.g. other non-Allocation Meters, protection, etc.. Local fusing shall discriminate with the source fusing. A typical arrangement is illustrated in Appendix C. Where CTs are used on low voltage installations, the voltage supply to the Metering Equipment shall be fused as close as practicable to the point of that supply with a set of isolating links provided locally, suitably identified, to the Metering Equipment. If that point of supply is close to the Metering Equipment, then the isolating links may be omitted.
