What arc flash protection methods are used by arc resistant switchgear?Other arc flash protection methods employed by arc resistant switchgear include, but are not limited to, the following. Workers who maintain and operate the switchgear must also wear the proper Personal Protective Equipment (PPE), which includes arc-rated clothing, gloves, face shields, and other gear.
What is switchgear arc protection?Switchgear arc protection mainly involves the use of vents and duct system to carry away the super-hot gases and high pressures of an arc flash away from the switchgear enclosure and to a safe location. This can be in the area above the switchgear or outside the switchgear room.
Can arc flash gases be vented outside a switchgear room?The flaps allow the heated gases of an arc flash and the pressure to safely vent out of the enclosure and away from the operator. When venting arc flash gases outside of the switchgear room is necessary, extra duct work is used. Depending on the manufacturer guidelines, a specified height clearance from the floor to the room’s ceiling is required.
