Abstract
An arc blast vent for an electrical equipment enclosure has a plate forming a part of the enclosure with triangular cutouts arranged within a regular polygonal area of the plate and having a frame of the plate material in between them. Substantially identical triangle shaped flaps, each having hold downs along and adjacent to a first leg of the triangle for attachment to the plate, and in from the first leg have a line of perforations through the triangle forming a weakened area for a deformable hinge. Each of the triangle shaped metal flaps have the second and third legs with their edges resting without tenacious engagement on the frame of the plate material.

An arc vent for an electrical equipment cabinet, comprising:
- a metal plate with four triangular cutouts arranged within a substantially square area of the plate and having a frame of the plate metal in between them;
- four isosceles triangle shaped metal flaps, each of said flaps having screw hold downs along and adjacent to a first leg of the triangle for attachment to the top plate, and in from the first leg a line of perforations through the triangle forming a weakened area for a deformable hinge;
- and
- each of the triangle shaped metal flaps having second and third legs with edges resting without tenacious engagement on the frame.
An electrical equipment cabinet with an arc vent, comprising:
- a top plate, side plates, and bottom plate forming the exterior of the cabinet;
- the top plate having four right triangular cutouts arranged within a substantially square area of the top plate and having a cruciform frame of the top plate material in between them;
- four substantially identical right angle isosceles triangle bendable flaps with a hypotenuse side, having mechanical hold downs on the hypotenuse side, and in from the hypotenuse side a line of perforations forming a deformable hinge;
- each of the right angle leg edges of the flaps resting on the cruciform frame.
An arc blast vent for an electrical equipment cabinet, comprising:
- a metal plate with a plurality of substantially equally shaped cutouts within a regular polygonal area, said cutouts having a frame of the plate metal in between them;
- a triangle shaped metal flap covering each cutout, each of said flaps having a hinge and mechanical hold downs along and adjacent to a first leg of the triangle for attachment to the plate;
- and
- each of the triangle shaped metal flaps having second and third legs with edges resting without tenacious engagement on the frame.
