a portable temporary cover installed in the doorway created by the open door, the cover exposing a part of the energized switchgear while covering a part of the energized switchgear so that a worker is enabled to work on the exposed part of the energized switchgear while being protected and insulated from the unexposed covered part of the energized switchgear,

wherein the portable temporary cover comprises a plurality of planar parts and attachment means for attaching the planar parts to each other and

wherein the planar parts comprise:

a main body having a planar front face and a side wall extending rearwardly from the main body front face into the cabinet, the main body side wall separating the exposed part from the unexposed part; and

a side box having a planar front face and a bottom wall extending rearwardly from the side box front face, the bottom wall separating the exposed part from the unexposed part.

2. The apparatus of claim 1 , wherein the portable temporary cover is made of a plastic capable of insulating the worker from the switchgear rated at 50 kilovolts (KV).

3. The apparatus of claim 1 , further comprising at least one handle extending outwardly from at least one of the planar parts, the at least one handle being C-shaped and of sufficient size to enable hands associated with the worker to grasp the at least one handle to install and remove the portable temporary cover from the cabinet.

4. The apparatus of claim 1 , wherein the attachment means comprises a plurality of screws with respective nuts that pass through respective holes in the planar parts.

5. The apparatus of claim 4 , wherein each of the planar parts has a planar front face and a side wall extending at a right angle from the front face in a rearward direction into the cabinet so that the side walls of adjacent planar parts are contiguous, each side wall having one or more of the plurality of holes that align with respective one or more of the plurality of holes of an adjacent side wall, the holes receiving the screws.

6. The apparatus of claim 4 , wherein the screws and wingnuts are made from nylon.

7. A portable insulating electrical switch cabinet cover for temporary installation in an energized electrical switch cabinet for insulating a worker from an energized electrical part while the worker performs a maintenance task, the cover comprising:

a plurality of parts, each part having a planar front face and a side wall extending at a right angle from the front face, each side wall having a plurality of holes;

a plurality of screws with respective nuts and passing through respective holes in order to attach the plurality of parts to create a parts combination having a front face;

at least one handle extending outwardly from the front face of the parts combination;

wherein the parts combination is of a size and shape to enable temporary placement of the parts combination within the energized electrical switch cabinet to expose a part of switchgear at the front face of the parts combination while covering a part of the switchgear at the front face of the parts combination so that the worker is enabled to work on the exposed part of the switchgear while being protected and insulated from the unexposed covered part of the switchgear; and

wherein the parts combination, screws, and the at least one handle are made of an electrically nonconductive material to protect from electrical power associated with the energized switchgear.

8. The cover of claim 7 , wherein the cover is made of a plastic capable of insulating the worker from the switchgear rated at 50 kilovolts (KV).

9. The cover of claim 7 , further comprising the energized electrical switch cabinet with an open door and wherein the cover is situated within a doorway created by the open door so that the worker is enabled to work on the exposed part of the switchgear while being protected and insulated from the unexposed covered part of the switchgear.

10. The cover of claim 9 , wherein the side wall of at least one of the planar parts extends rearwardly to an extent that is sufficient to extend between and separate the exposed part from the unexposed part.

11. The cover of claim 7 , wherein the handle has a C-shaped configuration and is of sufficient size to enable a hand associated with the worker to grasp the handle to install and remove the cover from the energized electrical switch cabinet.

12. A kit for assembling a portable cover for temporary installation in an energized electrical switch cabinet for insulating a worker from energized electrical parts while the worker performs maintenance tasks, the kit comprising:

a plurality of parts, each part having a planar front face and a side wall extending at a right angle from the front face, each side wall having a plurality of holes;

a plurality of screws with respective nuts, the screws having a size to enable passage through the holes in order to attach the plurality of parts in order to enable creation of a parts combination having a front face;

at least one handle extending outwardly from the front face of the parts combination;

wherein the parts combination is of a size and shape to enable placement of the parts combination within the energized electrical switch cabinet to expose a part of the switchgear at the front face of the parts combination while covering a part of the switchgear at the front face of the parts combination so that the worker is enabled to work on the exposed part of the switchgear while being protected and insulated from the unexposed covered part of the switchgear;

wherein the side wall of at least one of the planar parts extends from the front face to an extent that is sufficient to extend between and separate the exposed part from the unexposed part; and

wherein the parts combination, screws, and at least one handle are made of an electrically nonconductive material.

13. A method for enabling the worker to assemble and utilize the insulating electrical switch cabinet cover without de-energizing the switchgear within the electrical switch cabinet, the method comprising:

providing a kit as defined in claim 11 ;

attaching the parts to create the parts combination;

opening a door of the electrical switch cabinet in order to create a doorway and to expose the switchgear through the doorway;

placing the parts combination in the doorway of the energized electrical switch cabinet to expose the exposed part of the switchgear while covering the covered part of the switchgear;

performing a maintenance task on the exposed part of the switchgear in the cabinet;

removing the parts combination from the doorway of the energized electrical switch cabinet; and

closing the door of the energized electrical switch cabinet.
