My assumption before this video: - switchgear is only for mv, switchboard is for lv. - switchgear construction n partition: metal clad and metal enclosed, Switchboatd construction n partition: form 1 to 4 (iec) or nema 1 to 4 (ansi nema). - what you called lv switchgear, i usually named it lvmdp/lvmdb (and still switchboard) Whether the circuit breaker is withdrawable or fixed type. Would you mind to give me the standard in iec to that UL sir? I'm not very familiar with nema std.
It’sa shame to hear that there is technology to eliminate arc flash deaths, but it is not required in all buildings. I guess there’s a cost to human life ratio!
