The Box Around the Copper: IEC 61439 Switchgear Assemblies, Forms of Separation and Internal Arc
A technician at the Al Sahil Gas Complex racks a motor starter drawer back into a motor control centre, and a fault inside the cubicle turns into an arc. He walks away with a scorched sleeve, because the cabinet was built to survive. Khalid Mansoori and Hana Qureshi follow the investigation from the burn marks back to a set of tests done years earlier in a high-power laboratory, and to the question of what a switchboard really promises.
