Low Voltage Temporary Electrical Installation

INTRODUCTION

BS 7909 deals specifically with setting-up and use of temporary electrical systems in the events and entertainment industry. Temporary electrical systems are typically required to be set-up hastily in challenging conditions, which in turn leads to a heightened risk of damage or other problems. BS 7909 therefore requires systems to be designed in accordance with the IET Wiring Regulations (BS 7671) so that adequate protection against the risks of electric shock, fire and interference are ensured. A properly designed system is then deployed and managed in accordance with BS 7909. The  BS 7909 certification forms are available, the forms include completion certificate, schedule of test results and confirmation of electrical completion.

BS 7671 is the 18th edition and the current standard used in the UK. It came into effect from 1st January 2019 and is the national standard used for electrical installation and wiring safety across domestic, commercial, and industrial properties. BS 7671 covers circuits supplied at nominal voltages up to and including 1000V AC or 1500V DC. It also applies to Extra Low Voltage (ELV) ranges and Low Voltage (LV) ranges, across a variety of frequencies. It also includes the building regulations, competent persons scheme, permit to work and cabling. Earthing essentials with respect to electrical hazards for achieving a safe and secured electrical power system.
