Extra Low Voltage (ELV)

Former Community Member

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 ?

    Good point regarding the shared neutral component.


    And IMO the tangent is GOOD to go off on. 


    In response to the initial question. Treat as potentially live at up to LV  even IF connected at BOTH ends. Faults happen
