Electric Shock Protection Measures for Distribution Boxes
To minimize the risk of accidental electrical shock, all components and wiring terminal blocks with voltages exceeding 50V AC or DC must be rated as “touch-safe” per IEC 742 and IP20 standards. See Out-of-arm's reach or interposition of obstacles. These measures are used only in low-power circuits, and in particular circumstances as described in Extra Low Voltage (ELV). Fault protection can be. Circuits shall be protected against excessive overload by fuses or circuit breakers of the correct type and capacity. Such switches or controls shall be of approved design and. The method of which to analyze arc flash hazards has evolved through several iterations of NFPA 70E, NPFA 70, and IEEE 1584 standards which modified the calculation methods to provide more accurate data based on testing, as well as UL 2986.
