General Cable Support Information
NEC/CEC:
Listed for Ordinary Locations
Applications
• Used to support cables in vertical raceways or risers.
• Relieves the strain that would be placed on terminations, the
interior of panels, or other devices to which the cables are
connected.
• Properly designed cable supports must not only be capable
of supporting a given weight of cable with a good margin of
safety but must also support the cable without damaging the
insulation or excessively reducing the amount of insulation over
the conductor in the area where the cable is supported.
O-Z/Gedney™ has been furnishing Cable Supports to the
electrical industry for almost 100 years that meet these
requirements.
Spacing for Conductor Supports
Size of Wire
18 AWG thru 8 AWG Not greater than 30 (100) 30 (100)
6 AWG thru 1/0 AWG Not greater than 60 (200) 30 (100)
2/0 AWG thru 4/0 AWG Not greater than 55 (180) 25 (80)
over 4/0 AWG - 350 kcmil Not greater than 41 (135) 18 (60)
over 350 kcmil - 500 kcmil Not greater than 36 (120) 15 (50)

over 750 kcmil Not greater than 26 (85) 11 (35)
Support of Conductors
in Vertical Raceways
Certifications and Compliances
• Requirements for Cable Supports in the National Electrical
Code reads as follows: 300.19 Supporting Conductors
in Vertical Raceways. (A) Spacing Intervals - Maximum.
Conductors in vertical raceways shall be supported if the
vertical rise exceeds the values in Table 300.19(A). One cable
support shall be provided at the top of the vertical raceway or
as close to the top as practical. Intermediate supports shall be
provided as necessary to limit supported conductor lengths to
not greater than those specied in Table 300.19(A).
Example:
• A 10-story building contains a vertical conduit run from the
basement to the top oor, approx. 34 m (110 ft) in length. The
raceway contains 4/0 copper conductors. Per Table 300.19(A),
the unsupported cable length cannot exceed 25 m (80 ft).
Therefore, one cable support is required at or near the top of the
vertical riser, and one intermediate support is required at or near
the midpoint in the conduit run, assuring that any unsupported
cable length does not exceed 25 m (80 ft).

General Cable Support Information
NEC/CEC:
Listed for Ordinary Locations
Applications
• Two basic types of cable supports are offered for use with
non-armored cable. They both utilize the pOZi-grip™ Wedging
Plug. pOZi-grip™ is a unique manufacturing technique for lining
the cable grooves with a coarse grain grit using a high strength
epoxy adhesive. This grit improves the cable support holding
power and does not injure the jacket or insulation on the cable.
One Piece Plug Type "S"
• This type consists of a metal body having an insulating liner
with a knurled and tapered inside surface and a one piece
impregnated hardwood wedging plug having a groove for each
wire. This type support is recommended for use with all types
of non-armored cables 600 Volts or less, as it is the easiest to
install, impossible to install incorrectly and it provides
ventilation of the conduit. This design is used in our Types S
and D Cable Supports. The basic principles of their assembly
are illustrated below.
Type S
1. Screw body on the end of the
conduit or connector in place of the
regular insulating bushing.
Multiple Segment Plug Type "R"
• This type consists of an all metal body having a tapered inner
surface and a canvas bakelite multiple segment wedging plug
so constructed that each cable is supported between grooves
in adjacent segments. This construction provides the uniform
pressure distribution required by the softer types of insulations
frequently used at higher voltages. This design is used in
non-ventilating types R, DR, W, C, K and M, and
Ventilating Compound Types CMT, and V. The basic
principles of their assembly are illustrated below.
Type R
1. Screw body on the end of the conduit
or connector in place of
the regular insulating bushing.
COMMERCIAL AND INDUSTRIAL FITTINGS: RIGID AND IMC CONDUIT FITTINGS
2. Pull wires and arrange temporary
means of support.
3a. Remove all pulling compound from
wires in the area where they pass
through the cable support.
3b. Place the plug between the wires
as close to the top of the body as
possible. Care should be taken
to locate each wire in the proper
groove.
4. Tap the plug firmly into the support
body.

2. Pull wires and arrange temporary
means of support.
3a. Remove all pulling compound from
wires in the area where they pass
through the cable support.
3b. Place the segments of the plug
around the wires. Where more than
two segments are involved the top of
each plug segment has numbers at
each end and it is important that these
are paired with the corresponding
numbers on the adjacent plug
segments.
4. Tap the plug segments evenly and
firmly into the support body.

Drill Chart for Type S and D Cable Supports
NEC/CEC:
Listed for Ordinary Locations
HOW TO USE THIS CHART FOR S AND D CABLE SUPPORTS
(1) Select your conduit size and measure your cable diameter(s) which must t within the min/max range corresponding to the quantity of
cables in the white area of this chart. (Note: S and D Cable Supports must be used with two or more cables, 600 volts maximum)
(2) Cable diameters that fall within the gray area of this chart cannot be accommodated. Therefore a 3" Cable Support has a cable range of
0.261" up to 1.130". Cables smaller or larger cannot be considered.
(3) Example: A 3" Cable Support will be used for 3 cables at 1.051" and 1 cable at 0.384". Refer to the 3" Conduit Size column. We can t
4 cables between 1.011" to 1.070" therefore 3 at 1.051" will t. The fourth cable ts between 0.361" to 0.410" within the white area in
the 3" Conduit column. This drilling will work.
(4) Using the example above but the fourth cable is smaller at 0.216", this drilling will not work. The 0.216" cable falls into the 0.211" to
0.260" range which is within the gray shaded area of the 3" conduit column. In this case, we recommend using our Cable Supports with
R-type wedging plugs. See the R table below.
For combinations of cables that fall outside these parameters, please contact your local representative.
