    Abstract - (Show below) - (Hide below)

    Establishes requirements for junction boxes of surface- or flush-mounting in fixed wiring installations in a.c. and d.c. circuits where the voltage does not exceed 250V and where the conductors are not subject to mechanical tension in normal use. Covers junction boxes having fixed terminals with capacity for the connection of PVC-insulated and sheathed cables. Does not apply to junction boxes for use in conditions where special protection against the ingress of dust or moisture is required. Covers references, definitions, service conditions, classification, marking, materials, construction, earthing and terminals.
