This section starts with general guidelines for
installation of VITALink MC cables and pro-
ceeds with more detailed information based on
the type of installation.
General
VITALink MC is installed and supported in much
the same manner as other armored cables
whether surface mounted, suspended, in cable
tray or direct buried. The requirements of
UL System 120/ULC S139 FHIT7 120 should
be followed as applicable.
Where independent circuits are required or
desired, proper separation and segregation
should be maintained from other electrical
circuits.
All conductors of the same circuit and, where
used, the grounded conductor and all equipment
grounding conductors shall be contained within
the same raceway, or cable tray, unless other-
wise permitted in accordance with the NEC or
CEC as applicable. These requirements shall
apply separately to parallel circuits.
Where subject to physical damage, conductors
shall be adequately protected.
Metal components and cable armor shall be of
materials suitable for the environment in which
they are to be installed. Conservatively, a cable
jacket may then be used in direct burial installa-
tions, and embedment in concrete.
Metal raceways, cable armor, and, other metal
enclosures for conductors shall be metallically
joined together into a continuous electric conduc-
tor and shall be connected to all boxes, fittings,
and cabinets so as to provide effective electrical
continuity. Equipment grounding conductors
smaller than 6 AWG shall be protected from
physical damage by a raceway or cable armor
except where run in hollow spaces of walls or
partitions, where not subject to physical damage,
or where protected from physical damage.
Cable Support
Install supporting hardware at intervals not
exceeding 6 feet for nonfire rated areas. For
fire rated areas, see limits for UL System 120/
ULC S139 FHIT7 120 (4ft).
When transitioning from a straight run of
VITALink MC cable to a bend, use additional
supports at the start of the bend and the end of
the bend as shown in Figure 9.
For 14, 12, and 10 AWG conductor sizes, cable
shall be secured within 12 inches of boxes, cab-
inets, fittings or other cable terminations. It is
recommended that support systems be com-
pleted as soon as possible after the cable is
installed. Fasten the cable at the far end of the
6. Installation
