Surge Protection to BS EN/IEC 62305 Unit 11: Surge protection for ICT systems and inspection and testing of electrical installations with SPDs
BS 7671 Part 1 Regulation 132.8 requires protective devices to be protected against overcurrent suitably related to the characteristics of the circuit. This unit will introduce the relevant regulations in Part 5 as applied to overcurrent protection for SPDs. Examples are provided to outline the principles and concept design requirements for SPDs being used in data, ICT and hazardous location applications. This unit also discusses the requirements for inspection and testing of electrical installations with SPDs.
