Fusing and testing facilities. (A) Separate fusing must be provided locally for: (i) the Main Meter; (ii) the Check Meter; and (iii) any other Facility Metering Equipment burden. (B) Local fusing must discriminate with the source fusing. (C) A typical arrangement is illustrated in Appendix 1 of these TSRs. (D) Where CTs are used on low voltage installations, the voltage supply to the Facility Metering Equipment identified in paragraph (A) above must be fused as close as practicable to the point of that supply with a set of isolating links, suitably identified, provided locally to that Metering Equipment. If that point of supply is close to the Facility Metering Equipment identified in paragraph (A), then the isolating links may be omitted.
