Electrical Supplies, Installations and Equipment
The whole installation, including wiring, switchgear and any generator, should be installed in a safe manner by a suitably competent electrician who should provide a written 'sign off' certificate to confirm electrical safety once the installation has been completed.
The safety standard of the installation should be at least that of the current I.E.E Wiring Regulations.
A safe temporary electrical supply should ensure:
- The supply is protected by a suitable earth leakage device, I.e. a Residual Current Device (R.C.D), and has a maximum tripping current rating of 30 mA.
- The use of cables with the correct rating.
- All supply cables are positioned so they are NOT prone to physical damage, e.g., not through door openings, across the surface of walkways/roadways or coiled up.
- All cables are positioned so as not to cause a trip or other hazard.
- Any generator and/or electrical equipment, including switchgear, are satisfactorily guarded to prevent unauthorised access and/or interference.
- Any generator is supplied with a certificate to show it is electrically safe.
- All electrical equipment used at the event must be in a safe condition and suitable for that type of use, i.e., in the open air where it may get wet.
- It is recommended that generators should be diesel powered.
- If a generator is to be used then:
- Suitable arrangements for the refuelling of the generator and the storage of fuel will need to be made. Petrol generators will not be allowed on site due to its high flammability.
- A suitable fire extinguisher should be provided.
