Why it matters
Events bring power, crowds and weather together. Temporary systems must be designed, installed and checked so the public and crew stay safe.
The hazards
- Shock from damaged cables and connectors
- Trip hazards from cables in public areas
- Overloaded generators and distribution
- Water and weather
Stay safe
- Events normally run at 230V single-phase and 400V/415V three-phase, using blue and red connectors
- Systems should be designed, installed and inspected by competent people, following BS 7909
- Use RCD protection on circuits that the public or crew can reach
- Protect cables in public areas with cable ramps or fly them overhead
- Keep connectors off the ground and protected from water
- Don't overload outlets: check the load before plugging in
- Report damaged cables and kit straight away
Ask the team
- Who is responsible for the power system on this event?
- Where do cables cross public routes, and are they protected?
- What would you do if a distribution unit tripped?
