Information to help organisers and others plan, use and manage electrical equipment at an event safely.
Event organisers, contractors and others using electrical equipment must do all that is reasonably practicable to ensure that electrical installations and equipment at an event are properly selected, installed and maintained so as not to cause death or injury.
The following guidance will be useful and should be read in conjunction with GS50, see resources.
Note: GS50 outlines the risks and your legal duties and general advice on managing electrical safety. It also gives more specific advice on ways to prevent electrical danger at fixed electrical installations.
Where possible, locate the main electrical intakes and/or generator enclosures where they are accessible for normal operations or emergencies, but segregated from public areas of the venue. Display danger warning signs around the intake or enclosure.
To prevent danger, construct or protect electrical equipment that could be exposed to rain or other adverse conditions with suitable and sufficient covers, enclosures or shelters. As far as practicable, locate all electrical equipment so that members of the public or unauthorised workers cannot touch it.
Select and rate all cables to meet electrical safety standards and to withstand any unusual environmental or adverse weather conditions.
Route cables to minimise tripping hazards or potential mechanical damage, and in a position that allows them to be safely installed and removed. Give particular care to the position of cable connections.
You can also use cable ramps or similar to protect cables running overground across route ways to help avoid them becoming tripping hazards.
Running cables alongside existing or temporary fence lines is advisable and it is important to segregate vehicle traffic and cable routes wherever possible. If this can't be achieved, you can route the cable by a cable bridge, a supporting catenary or cable ramps.
If the cable is to be routed using a cable bridge or catenary, a height of not less than 5.8m is advisable to make sure that most vehicles can pass beneath it. Advisory notices, warning of the location of the overhead cables, should be clearly displayed in both directions. Use fences to segregate roadways from overhead cables running parallel to the roadway to prevent inadvertent contact.
If you need to run cables underground, ideally use cable ducts or pipe, suitably sized to accommodate connectors. Do not leave cable joints underground. Follow the further guidance on burying cable in BS 7671.
