To accommodate future serviceability, the manufacturer
recommends that the head of the carriage bolt should be mounted
from the rear of the switchboard for FRONT ACCESSIBLE
switchboards with the hex nut with Belleville washer positioned to
the front .
For REAR ACCESSIBLE switchboards, the manufacturer
recommends that the head of the carriage bolt should be mounted
from the front of the switchboard with the hex nut and Belleville
washer positioned to the rear .
Repeat the process until all holes in the horizontal bus are connected
with bolts and nuts for each shipping split . Inspect connections to
ensure that there is no foreign material at the connection point and
that all connections are properly aligned and bolts are seated .
Torque all connections to torque requirements on labels affixed to
each switchboard and as shown in Appendix
Table 2
.
IFS switchboard factory cabling
Some switchboards utilize cable/wire for some connections in lieu
of bus . Cabling is typical in Integrated Facility System™ (IFS™)
type switchboards that incorporate lighting and appliance branch
circuit panelboards and dry-type distribution transformers within a
switchboard lineup .
Eaton’s selection of wire and cable follows CSA 22 .2 NO .31
switchboard procedures, and the Canadian Electrical Code standards
for IFS switchboards .
The manufacturer identifies each phase conductor by means of color-
coded tape if required . Markings are affixed to both the line and
load ends of the conductors . Markings follow the industry accepted
phase colors . (See
Figure 14
and
Table 1
.)

Conductors installed by the manufacturer have been cut and stripped
to pre-determined lengths for connection between components .
When conductors are intended to run between components in
two different sections that are joined by the manufacturer, the
manufacturer will connect both the line and load ends of the
conductors .

The Canadian Electrical Code restricts the field installation of
conductors that run horizontally through switchboard vertical sections . Refer
to the CEC for specifics .
When there is a shipping split between sections that are cabled,
the factory connects one end of the conductor s . The remainder
of the conductors are coiled and secured in the section with the
connection .
Factory drawings included in the switchboard clearly indicate the
required field connections for the coiled conductors .
Inspect conductors/cables for damage . Any damaged conductors
must be replaced . Contact manufacturer for replacement .
Factory color-coded markings indicate phasing/neutral and are
marked on both the line and load ends of the conductors
Using the factory drawings, the installer connects conductors to the
component(s) indicated on the drawings keeping phases correctly
oriented . Care should be taken in forming insulated cables to ensure
that no insulation is forced permanently against edges of any metal
parts .
Torque both line and load connections to values indicated on the
labeling on the switchboard . Refer to Appendix
Table 2
for torque
values .
Installation of incoming switchboard connections
DANGER
DE-ENERGIZE SWITCHBOARD — HAZARDOUS VOLTAGE. WILL CAUSE
SEVERE INJURY OR DEATH.
DO NOT work on electrical equipment while energized . Verify power
entering the equipment is de-energized at the source .
Power is normally brought into a switchboard either by cable or by
busway (busduct) .
Remove structure covers as needed to access switchboard chassis
and components . Retain all cover mounting hardware and covers for
re-assembly . Protect hardware and parts from moisture, debris and
damage .

As a minimum, all switchboard connections are rated for use with
75°C or higher rated conductors . When wire is used with temperature ratings
above 75°C, it shall be sized based on the ampacity of wire rated 75°C .
Wire/cabling
When cable connections are used, either mechanical set screw
or compression lugs are typically supplied . (See
Figure 15
.) See
factory drawing for specific lug terminations and wire ranges . Some
utilities make their own service entrance connections . In these
cases, the manufacturer typically supplies lug landing provisions or a
landing pad in lieu of lugs . These are designed to the specific utility’s
requirements . Refer to the manufacturer’s drawings for specifics
covering this connection .
