Abstract

A method for isolating phases in an electrical equipment enclosure having multi-phase bus bars and a mounting base for mounting electrical equipment. The insulation system includes a plurality of components including a plurality of side isolation barriers with each barrier defining at least one slot proximate one edge of the barrier and having at least one tab along another edge of the barrier. A side barrier adapter is configured to engage the isolation barrier and to engage the mounting base. An inner isolation barrier is configured to isolate at least two of the vertical bus bars and couple to the mounting base. A vertical bus rear wall defining a plurality of slots proximate at least two edges of the cover is fastened to the inner isolation barrier. A plurality of corner connectors is configured to engage one of the cover slots and the side isolation barrier slots.

Claims

1. A method for isolating phases in an electrical equipment enclosure having vertical bus bars and a mounting base for mounting electrical equipment, the method comprising the steps of:

providing a plurality of side isolation barriers;

providing a side barrier adaptor;

coupling the side barrier adaptor to the mounting base and at least one side isolation barrier;

providing an inner isolation barrier,

coupling the inner isolation barrier to the mounting base to isolate at least two of the vertical bus bars from each other;

providing a vertical bus rear wall,

providing a plurality of corner connectors; and

coupling the vertical bus rear wall and at least one side isolation barrier to at least one corner connector, wherein the vertical bus bars are individually isolated from each other.

2. The method of claim 1, including the step of configuring the vertical bus rear wall with an opening for a runback bus bar.

3. The method of claim 2, including the steps of providing insulation shrouds and coupling the insulation shrouds to the runback bus bars.

4. The method of claim 1, including the step of installing a split bus barrier between sections of the vertical bus bar.

5. The method of claim 1, wherein the side isolation barrier, side barrier adaptor, inner isolation barrier, vertical bus rear wall, and corner connectors are composed of one of thermoplastic and thermoset material.

6. The method of claim 5, wherein the thermoplastic is a clear polycarbonate.

7. The method of claim 4, wherein the split bus barrier is composed of one of thermoplastic and thermoset material.

8. The method of claim 1, including the step of only using a screw driver to assemble and disassemble selective modular insulation system components.
