What is It
Lesson 2.4
Week 4
FLEXIBLE ARMORED CABLE WIRING
Flexible Armored Cable (type AC) is a fabricated assembly of insulated
conductors walled in flexible metal sheath. It is commonly known as
BX. It consists of spiraled metal sheet forming flexible steel tube through
which the rubber covered wires are enclosed. The armor protects the
wires from injury and to some extent from moisture.
FLEXIBLE ARMORED CABLE (BX)
Type of flexible armored cable
1. Types AC- The conductors inside are insulated with rubber
insulation.
2. Type ACT- The conductors inside are insulated with
thermoplastic insulation.
3. Type ACL- Has a rubber and lead sheath between the conductor
and the armor.
4. Type ACV- Has a varnish cambric insulation. Varnish cambric is a
closely woven fabric of cotton or linen impregnated with insulating
varnish.
Usages of Flexible Armored Cable
o Type AC and ACT
• Used for both exposed and concealed work in dry
locations.
5
•
Can be embedded in plastic finish on brick or other
masonry work except in damp and wet locations.
o Type ACV
• Used only for exposed work in dry locations in buildings
used for industrial or commercial purposes.
• Shall not be smaller than 5.19mm.
o Type ACL
• Can be used when exposed to weather or continuous
moisture.
• For underground runs and embedded in masonry,
concrete or buried in building during constructions.
• Where exposed to oil, gasoline or other conditions having
deteriorating effect on the insulation.
Flexible Armored Cable must not be used in
o
o
o
o
o
o
o
Theaters
Motion picture studios
Hazardous locations
Where exposed to corrosive fumes and vapors
Storage battery rooms
Cranes and hoist
Hoistways or elevators
Supports
Flexible Armored Cable must be secured by approved clamps,
straps or similar fittings so designed and mounted not to injure cable.
The cable shall be secured at the wired surface approximately every 1
meter interval and within 30mm away from outlet box or fittings.
Exposed Work
Expose runs of cables must follow closely the surface of the
building finisher of running board except:
o lengths of not more than 60 cm where flexibility is desired;
o on the undesirable of floor joist in basements where supported at
each floor joist and so located as not to be subjected to mechanical
injury;
o in accessible attics and roof spaces, cables shall be installed as
follows:
• where run across the top floor joist of within approximately 2
meters of floor joist across the face of rafters, the cable shall
be protected by guard strips which are at least as high as the
cable. When this space is not accessible by permanent
ladders or stairs, protection can be required within 2 meters
from the attic entrance.
• Where cable is insulated along the sides of rafters, studs, or
floor joist guard strips or running boards are not needed.
6
Protection of Cable Ends
At all points, where the cable terminates, a fitting should be
provided to protect the wires from abrasion, unless the design of the
outlet box is such that it affords equivalent protection to the wires. An
approved insulating bushing should be installed between the conductors
and the armor.
Electrical Continuity of Metal Enclosure
The metal enclosure consists of the cable armor and any outlet
boxes or other box fitting, or cabinets used as electrical continuity shall
be ensured by setting up tightly all connectors, clamps, and locknuts.
Grounding
The cable armor and all other parts and enclosure will be
effectively grounded if electrical continuity is ensured through the wiring
system.
Cutting
In cutting a flexible armored cable the appropriate tools to be used
is hacksaw.
Bends
In making bends, precautions must be made in order not to injure
the armor of the cable. The diameter of any bends should not be less
than 5 times the diameter of the cable.
Boxes at Outlets and Free Lengths of Conductor
A box shall be installed at each outlet, switch, or junction points of
the armored cable. At least 150mm of free conductor shall be left at each
outlet and switch points for making up of joints or connections of
fixtures or devices, except where conductors are intended to be looped
without joints.
General Requirements for Wiring Methods
Protection against corrosion and mechanical injury in metal
raceways, armored cable, boxes, cabinets, metallic elbows, coupling, and
fitting, unless made of corrosion resistant material inside and outside
shall be coated with zinc, cadinium and enamel. Except that ferrous
raceways fittings and boxes protected solely with enamel may be only
indoors and occupancies not subject to severe corrosion influences. The
following are judged to subject to corrosive conditions:

FLEXIBLE METALLIC TUBBING (FMT)
INTRODUCTION
Flexible metallic conduit is a kind of wiring installation which is
commonly used for external motor terminal connection. It is being
manufactured in rolled in the form of coil

•
when exposed to oil, gasoline or materials which affects rubber
A flexible conduit consists of flexible steel tube which is made from
convex to concave metal strip in a spiral winding with length from 50 to
200 feet.
Flexible metallic conduit should be supported with a distance of
136cm or closer. Every turn should be done carefully to avoid deformity.
Straps or clamp can be used to secure the conduit.
Flexible metallic conduit (FMT) is used in a connection where the load
being supplied no definite place where flexibility is desired. Some
common equipment are the portable motor, drill press lathe machine and
the like.
The minimum size of this type of conduit ranges from ½ to 1 ½ inches
