Extra Low Voltage (ELV)

Former Community Member over 4 years ago

Guys,

BS7671:2018 is classing cables extra low voltage (ELV) as an operating voltage not exceeding 50Vac or 120V ripple-free dc.

BS7671 goes on to further categorize ELV cables into SELV, PELV, FELV.

For single core green/yellow insulated equipotential bonding cables lets say originating from an earth bar and bonding some structural steel work, are these classed as FELV under BS7671:2018 ?

BS7671:2018 mandates different criteria in relation to the voltage category of a cable be it LV, RLV, SELV, PELV, FELV. Before we can review against the relevant criteria we must establish which of these categories a cable belongs to. I am wanting to establish the correct category under BS7671:2018 in relation to a single core green/yellow insulated equipotential bonding cables originating from an earth bar and bonding some structural steel work.
