Rough-in Conduit and Wiring

Rough-in Line Conduit to the Auxiliary Enclosure

Line input wires in main lug, main breaker, or cross-bussed DRd enclosure applications

terminate first in the Auxiliary enclosure and then are fed through the side conduit

knockouts to the adjoining DRd enclosure(s).

The line feed-through (interconnect) cables for phase, neutral and ground lugs in the

auxiliary enclosure are connected for you at the factory. Your enclosure is supplied with one

or two sets of interconnect cables depending on the model ordered.

Step 1:

Plan wire entry in to the enclosure.

Step 2:

Remove the side conduit knockout from adjoining side of the auxiliary enclosure

and the DRd enclosure. When installing in a cross-bussed application, remove

both side knockouts.

Step 3:

Install the ETC supplied nylon insulated chase nipple to the knockouts between

the auxiliary and DRd enclosure(s).

Step 4:

Remove the auxiliary enclosure front cover, and if necessary, the top or bottom

front trim covers for complete access to the lugs.

Step 5:

Punch conduit holes, top or bottom, as required by the wire entry plan.

Step 6:

Install conduit fittings or insert fish paper lining material into the opening.

Step 7:

Be sure there are minimal air gaps.

C A U T I O N :

Wire openings must have fittings, grommets or fish paper lining material to protect

wire and cable insulation from damage by sharp metal edges and to prevent air

leaks.
When using the 400A breaker frame you must replace the plastic lug covers for

compliance and safe operation.

Line input may enter the auxiliary enclosure from

the top or bottom.

The ETC supplied line feed interconnect cables

will feed through the side conduit knockouts to the

adjacent DRd. Reference
