Once the conductors are pulled inside the main section, the
cables should be formed in the space provided . Clearly identify and
segregate conductors by phase and neutral . Care should be taken
in forming insulated cables to ensure that no insulation is forced
permanently against the edges of any metal parts .
Using appropriate tools, the installer must strip the conductor insula-
tion sufficiently to fill the entire barrel of the connector with bare,
un-insulated conductor . Conductor must be stripped without damage
to the conductor strands . Bare strands should be of equal length
(flush) on the end cut .
Do not strip off more insulation than needed . Exposure of bare
conductor outside lug can compromise clearances .
The connector and conductor should be free of all foreign debris .
Never clip cable/wire strands in order to fit within connectors . If
cable/wire does not match the rating of the connector, contact
the manufacturer .
Mechanical set screw lugs are the most common . Use an antioxi-
dant compound, if required . Insert bare conductor into lug so the
bare conductor fills the full length of the lug body . Tighten lug, then
torque to levels indicated on the switchboard label .
If compression lugs are used and supplied with the switchboard, the
lugs will be mounted on the incoming lug pad . Remove lugs from
the pad . Use an antioxidant compound, if required . Use a crimping
tool approved for that specific lug manufacturer and lug size . Follow
instructions provided by the manufacturer of the crimp tool .
Once the lug is affixed to the conductor, re-install the lug on the lug
pad using the existing hardware . Torque hardware using information
provided on switchboard labeling . Refer to
Appendix A, Table 2
for
torque values .
Other requirements for rear-connected switchboards
On systems that require short-circuit current ratings above 10,000A
rms, cable bracing may be required to restrict cable movement .
Lashing and lacing cables accomplish this .
Cable bracing instructions
For short-circuit ratings above 10,000A rms, install cable braces
per the following instructions:
1.
The material required for the cable braces is 3/8”diameter
nylon rope
a
or any rope having a minimum tensile strength
of 2,000 pounds
b
.
2.
All cable conductors of a load circuit are to be bundled together
with five adjacent wraps of rope at distances of 6 inches and
12 inches from the supply terminals for ratings up to 200A
maximum . (See
Figure 20
and
Figure 21
.)
