In one aspect, an arc fault relief panel is provided for mounting to a cabinet for enclosing medium- or high-voltage electrical equipment. The panel includes bend relief cuts or slots to allow the panel to fail in a predictable manner during an explosive arc fault. That is, the cuts or slots provide weakened locations or segments along the panel that permit a main portion of the panel to bend outwardly during an explosive arc fault. The main portion of the panel may be secured to other components of the cabinet with tear-away fasteners. During an explosive arc fault, the panel tears away from the fasteners, allowing the panel to bend outwardly along its weakened segments to provide an opening for venting pressurized air. A lanyard cable may be used to restrict outward movement of the main portion of the panel to help protect adjacent equipment or nearby personnel. |
