This extract from ER G12/issue 4 Amd 12015. Is it common practice for a gas pipe to have a insulated insert? Certainly not here.
5.2 Earthing terminal
5.2.1 Provision of earth terminal
PME earth terminals can be offered to consumers unless there are reasonable grounds to believe either:
- their earthing installation is not designed to BS 7671.
- or
- the type of installation is not suitable for PME. (See Section 6 for examples where it may not be possible to provide a PME earth terminal).
Where a metallic gas service is provided to a consumer’s premises with a PME earth terminal, an insulated insert should be fitted in the gas service.
