Earthing

Shock protection starts at the meter supply earth wire or a local earth electrode in the ground connected to the consumer unit/fuse box and onwards to all of the property metalwork. HIP requirement.

Meters

Main water and gas are connected to the consumer unit earth point with 10mm earth wire. The pipes from the meters are then connected together as supplementary bonding the bathroom in particular, pipes, hot water tanks, the central heating system pipework and any exposed metalwork.

All Exposed

Metalwork from the pipes to the radiators to avoid electric shock from stray electricity within the property. Preventing accidents is paramount and prevention is based on both previous incidents and risk assessment to avoid any incidents reducing injury and insurance premium and cost reduction.

Pipework

Throughout the premises in particular the bathroom where water and metalwork can become in contact and exposed to the touch.

CH Boiler

May seem unnecessary and expensive but it’s a must to protect lives from stray electricity as the metal underground pipe work used in the old days to provide an earth path for the fault current to flow are being replaces by PVC pipes. This is why the earthing has to be done as a deliberate act throughout the property as opposed to relying on incidental protection.

Radiators

Particular the ones of late on the speedfit plastic heating pipe installations have to be bonded with separate 6mm wire ensuring there is earthing on all metalwork within the property for safety.
