7. Post Installation
The following section provides general infor-
mation on post installation activities including,
cable terminating, splicing, and testing.
General
A sufficient length of cable should be removed
from the pulling end to ensure that an adequate
length of undamaged cable is available for ter-
mination. Cables that are electrically paralleled
for the same circuit should be cut as closely as
possible to the same length prior to termination.
The cable(s) should be identified with noncon-
ductive tags on both ends of the installation.
Cable slack should be provided at transition
points between non-connecting trays or race-
ways, and equipment. A sufficient length of
cable core should be pulled into equipment,
panels and boxes to permit neat arrangement of
conductors and compliance with the following:
• Cable should be trained so that the minimum
bending radius for permanent training is not
violated.
• Any minimum required separation distance is
maintained.
Terminating VITALink MC at
Electrical Switch Gear/Equipment
A junction box is optional on either end of the
fire rated cable in the fire rated room per the
following (see Figure 10):
a) Once the cable enters the fire rated room,
a minimum of 12 inches, terminate the
VITALink MC cable into the appropriate size
junction box per NEC or applicable CEC.
Use UL/ULC listed MC connector suitable
for a corrugated copper sheath, a UL/ULC
listed lock nut and insulating bushing to ter-
minate the cable to the box. Connector
should be suitably grounded. Equipment
grounding conductors should be carried
through and maintained as required. Utilize
a grounding hub as required.
b) Using the appropriate raceway for the spec-
ified area, connect the junction box to the
equipment.
c) Install appropriate wiring between the junc-
tion box and the equipment.
d) Splice VITALink MC to the wire using an ap -
proved method. Note a transition splice may
be required based on ampacity considerations.
e) Seal the end of the raceway in the junction
box to keep gases from migrating down into
the equipment in the case of a fire. This may
be done using a pliable compound.
Note 1: All wiring methods and installation pro-
cedures shall comply with NEC /CEC and local
amendments.
Note 2: NEC Article 110.14 should be consid-
ered in regard to the temperature limit of the
wiring to the equipment. The VITALink MC
cable may be sized at 90°C if so desired. CEC
requirements shall be observed as applicable.
