Specialist Earthing Services

Earthing creates an alternative path for the flow of fault or excessive currents safely to ground. It is an integral part of any electrical system and essential in keeping both people and equipment safe.

The current British Standard Code of Practice regarding earthing is BS 7430:1998 (ISBN 0 580 28229 5).

The general provisions in the Electricity Supply Regulations apply to both overhead and underground systems of supply. The regulations require at least one point of every system to be connected with Earth.

  • Regulations 4 to 8 of the current Electricity Supply Regulations
  • The Electricity at Work Regulations 1989.
