What is BS 4444 – Electrical earth monitoring and protective conductor about?
The possibility of damage to, disconnection from, or a rise in impedance of, any protective conductor, cannot be eliminated by periodic inspection and, in any event, accidental damage could occur between inspections. BS 4444 is a British standard that discusses earth monitoring devices that are intended to maintain a continuous check on the integrity of the protective earth conductor.
Earthing is used to protect you from an electric shock. It does this by providing a path (a protective conductor) for a fault current to flow to the earth.
BS 4444 outlines the principles involved in the design and construction of earth monitoring, earth proving and insulation monitoring devices, together with the requirements for their safe use and application.
