Equipotential bonding

Equipotential bonding is an electrical safety measure that uses bonding conductors to connect specified metalwork or conductive parts so they are less likely to sit at different touch voltages during a fault. In home energy work, the term may appear in electrical certificates, condition reports, Part P information, EV chargepoint paperwork and handover packs for solar, battery or heat pump installations. It is different from earthing: earthing provides a fault-current path to earth and helps protective devices operate, while bonding reduces voltage differences between conductive parts that could be touched at the same time. A mention of equipotential bonding does not say what work is needed, prove that bonding is adequate, confirm DNO acceptance, prove product compatibility or replace competent assessment of the actual installation.
