OVERVIEW
Lake Shore Electric’s Quick Connection Cabinets (QCC)
are intended to provide a temporary connection to an
emergency generator and a permanent connection to a
building load.
QCC INSTALLATION
IMPORTANT! When cables must be connected or
disconnected to the QCC, the generator must be “OFF”!
Once determining the appropriate size cable to connect
the QCC to the building load, conduits must enter from
either the top or rear of the cabinet. If from the rear, they
must be as close to the top as possible to allow for
adequate cable bend area. Additionally, consideration
must be given when rear connected to insure the conduit
hub does not interfere with the mounting of the cabinet.
NEVER enter conduits from the bottom or the sides of
the cabinet. In order to maintain the Nema 3R and
Nema 4 ratings, insure that appropriate gaskets and/or
seals are utilized during installation. The cabinet must
be mounted level to allow for proper drainage through
the integral weep holes located in the bottom of the unit.
THE STANDARD QCC PRODUCT DOES NOT
PROVIDE OVERCURRENT PROTECTION OF ANY
KIND. IT MUST BE PROTECTED BY AN UP-STREAM
CIRCUIT BREAKER TO MAINTAIN REQUIRED SHORT
CIRCUIT RATINGS.
Confirm that the generators voltage and phase sequence
match that as provided with the QCC unit. The Cam-
Loks are color coded with voltages and phase
sequences clearly marked on a label inside the lower
access door as well as included on the Outline drawing
provided in the print pocket located inside the front door.
Minimal periodic maintenance is required other than
visual inspection to insure proper operation. Inspect
sealing of the doors and gaskets and check that the
proper torque is maintained on the compression lugs
(supplied by installer) at the load connection to the bus
bars.
The required torque values are visible on a label located
on the inside of the front door as well as on the Outline
drawing located in the print pocket.
