Panels to Fit Existing Enclosures
Panelboard interiors and special fronts can be furnished to fit existing enclosures. First, price the complete panel along with the appropriate price adder from below. Next, photocopy the Retrofit Existing Enclosure data sheet found on Retrofit Existing Enclosure Data Sheet, record the required dimensions on the photocopy and forward it with your order to the nearest Schneider Electric sales office. For interiors requiring vented enclosures, contact your nearest Schneider Electric sales office for assistance.
note
Existing enclosure depth on flush installations must be measured from inside surface of enclosure to outer wall or plaster surface.
Special Fronts
Existing enclosure the same depth as or deeper than our standard.
note
Elevating brackets to be supplied by customer for existing enclosures deeper than our standard.
Existing enclosure shallower than our standard. Requires an enclosure
extension (surface applications) or
a formed front
(flush applications). A hinged trim front option is not available
for these applications.
note
A formed front is available on NQ (225 A max.) and, NF (250 A max.). When a flush front is required for an existing enclosure that is shallower than our standard, be sure to indicate the position of the enclosure with respect to the wall in which it is mounted. This is required in order to determine whether an enclosure extension with a flat front should be supplied, or whether a flush formed front is more applicable. The interior must be centered in the enclosure and, if the enclosure is deeper than our standard, the interior must be leveled within the enclosure. The existing enclosure for NQ and, NF panels cannot be more than 3.0 inches shorter than the standard enclosure. Minimum width is 17 inches. Special trims that are manufactured to fit an existing enclosure will be within ± 0.25 inches of the specification. Refer to the table below for standard enclosure depths and for the maximum depth for which no special mounting brackets are required.
