ENCLOSURE MOUNTING INSTRUCTIONS
IImmppoorrttaanntt::Read these instructions carefully to assure proper installation and
assembly. Ensure all fasteners and connections are properly
tightened (refer to torque information label E3A1064 on panelboard)
A separate booklet NEMA Standards Publication ANSI/NEMA PB 1.1-2007 titled
“
General Instructions for Proper Installation, Operation, and Maintenance of
Panelboards Rated 600 Volts or Less ” was provided with this equipment. You
should become familiar with the contents of this booklet before proceeding with
these specific instructions. An electronic version is available from the NEMA
website: http://www.nema.org/stds/pb1-1.cfm#download.
*NEMA 3R enclosure is bottom feed only.
NEMA 1 flush or surface mount enclosure. NEMA 3R* surface mount enclosure.
1. Mount NEMA 1 box or NEMA 3R* enclosure per ANSI/NEMA PB 1.1 instructions.
NEMA 1 enclosure box can be rotated 180° to accommodate conduit feed.
2. If installing NEMA 1 flush mount panelboard, make allowances for finished wall
thickness.
3. Install “Grounding Bar” and “Neutral Bar” using supplied #10-32 x 1/2” long screws.
• NEMA 1 box: Grounding Bar and Neutral Bar may be installed on either side (one
bar per side) of the enclosure to facilitate wire routing needs.
• NEMA 3R enclosure: Remove left and right side deadfronts. Install Neutral Bar on
the left side and Grounding Bar on the right side. Reinstall deadfronts to their
original positions.
4. Tighten all fasteners and connections to specified torque values.
5. If panelboard is installed as a SERVICE ENTRANCE, install Neutral Bar bonding wire per
the following instructions.
Deadfronts

NEUTRAL BONDING WIRE INSTALLATION
For SERVICE entrance installations, install bonding wire between the neutral bar
stud using 1/4-20 hex flange nut and enclosure using #10-32 x 1/4” long screw, as
shown in the illustration below, and tighten fasteners to specified torque values.
CHASSIS INSTALLATION
NNoottee::The NEMA 1 panelboard chassis can be rotated
180 degrees to meet bottom or top conductor feed
requirements. NEMA 3R is bottom feed only.
1. Align mounting holes on chassis with studs on
back wall of enclosure.
2. Secure chassis to enclosure using four (4)
1/4-20 hex flange nuts and torque to
35 Lb-In (2.8 N•m).
3. As necessary, drill holes or remove knockouts and
feed conductors as needed using appropriate hardware
(see NEMA PB 1.1).
4. Check that all fasteners and wire terminals are tightened to specified torque values.
5. Install deadfronts and trim as required.

DOOR-IN-DOOR LATCH ADJUSTMENT
For NEMA 1 installations with the Door-in-Door front;
if the door trim latch does not engage the latch bracket:
1. Make sure door latch bracket is installed
on correct side of chassis. If not, remove
retaining screws and reinstall bracket
on other side.
2. Adjust bracket by loosening the two
retaining screws.
3. Reposition door latch bracket for
proper engagement with door latch and
retighten retaining screws.
NNOOTTEE::Neutral bonding wire is to be installed only when panelboard is installed as
SERVICE equipment.

CCPB BRANCH DISCONNECT
INSTALLATION AND REMOVAL INSTRUCTIONS
Electrical equipment may contain hazardous voltages. These
can cause electrical shock, burn or death.
Only qualified personnel should perform procedures involving
electrical equipment. Always properly ground equipment and
lockout electric power (de-energize) before accessing electrical
equipment and enclosures. All unused branch circuit positions
must be filled with blank covers before energizing panelboard.
Take note of and follow all safety instructions in this Instruction
Leaflet.

The CCPB branch disconnects come factory installed. If it is necessary to replace
or install additional CCPB branch disconnects, order as many as required. Be sure
to specify the correct ampacity rejection rating and number of poles for the circuits
being added (see replacement parts list on page 13) and follow the installation
steps below:
1. De-energize and lockout panelboard power supply.
2. Remove branch circuit deadfront.
2a. Remove branch circuit knockout(s) from deadfront where CCPB is being installed.
3. On the CCPB to be installed, push the switch to the “OFF” (O) position and remove
fuse (if present).
4. Align “T” slot on CCPB with branch sub-assembly and slide CCPB into
position until fully seated.
5. Align hole on CCPB bus tab with hole on bus bar, insert #10-32 x 1/4” screw and
tighten to 25 Lb-In (2.82 N•m) torque.

FUSE REPLACEMENT
1. Prior to replacing any open fuse, follow safe
work practices*.
2. Locate open fuse indicated by indicating lamp**
or open fuse indication on CUBEFuse®
(if equipped).
3. Turn switch to the “OFF” (O) position.
4. Lockout/tagout CCPB per OSHA requirements.
5. Correct the overcurrent condition.
6. Pull fuse straight out.
7. Note fuse amp rating.
8. From the spare fuse compartment, select a
replacement fuse of equal amp rating.
NNoottee::Fusible branch circuit switches are
ampacity-rejecting. Replace fuse only with one
of equal rating. If a replacement fuse with equal
rating is not available, order one from a Cooper
Bussmann distributor. If the distributor does not
have a replacement in stock, place an order for
an emergency*** fuse shipment, call 636-394-
3877 between 8:00 A.M. and 4:30 p.m.
Central Time, or 314-995-1342 for after hours
service.
9. Insert replacement fuse until fully seated.
10. Remove lockout/tagout.
11. Turn switch to the “ON” ( I ) position.
12. Make note of fuse inventory in spare fuse compartment and order replacement fuses,
in the appropriate amp ratings, as needed.
