Wiring Matters 2025 Annual
We hope you enjoy the Wiring Matters 2025 Annual. In this special edition of Wiring Matters, we collect articles that generated particular interest in 2024 in one place.
About the Annual
The 2025 Annual includes:
- an explanation of which conduits and ducts offer equivalent mechanical protection to armoured cables when buried in the ground
- an article from our popular “Mythbusters” series, challenging the notion that event distribution boards with socket-outlets are not permitted for use on construction sites
- a look at the topic of selection and erection of protective devices for alternative supplies, such as photovoltaic and energy storage systems, where there is bidirectional power flow
- details of why the values of maximum earth fault loop impedance are different in BS 7671 to the IET’s On-Site Guide and Guidance Note 3: Inspection & Testing
- an exploration of the background of competency in the electrical installation industry and what it means
- a look at how reducing the current-carrying capacity of a circuit without overcurrent protection may not be as bad as it first seems.
