Arc flash requirements when working in electrical panels ? PPE, arc flash calculations/boundary etc . Struggling to find any information !

James Purdy

Hi everyone, im after some help!

I work for an American company who have a lot of requirements and procedures for determining Arc flash but are all US and OSHA regs and rules. My team work on CNC equipment so our work is mainly live testing on 3 phase and low voltage circuits in panels. I'm trying to determines the UK requirements for Arc flash. I'm needing to know info like Arc flash boundary, how to determine PPE, calculations etc.

Any help would be great !

    Working dead is the default UK approach in general because of Regulation 14 of the Electricity at Work Regulations 1989, and the use of appropriate test equipment and leads and working practices to help eliminate risk is also a default position in low voltage installations (for example, see HSE Guidance Note GS38, www.hse.gov.uk/.../gs38.htm)
