Conduit Cable Tray Clamps and Grounding
Conductor Clamp
Type TCC Single and TCCD Double Supporting Clamps,
and TCGC Grounding Clamp.
Applications: TCC and TCCD
•
For supporting rigid conduit to cable
tray flange at each location where tray
cable exits the tray and is run through
rigid conduit raceway to control panel
boards, motor starters and other elec-
trical devices.
Applications: TCGC
•
To provide a means for securely at-
taching a grounding conductor to cable
tray to maintain grounding continuity
for the entire cable tray system.
•
To protect equipment through a
reliable method for carrying ground
fault currents.
•
For installation indoors or outdoors,
with most types of cable trays with in-
side or outside flanges.
Features: TCC and TCCD
•
Clamps mount on all types of tray
configurations (inside, outside or dou-
ble flange).
•
Exclusive design provides full 360°
swivel, allowing exit conduit position-
ing at any angle, eliminating the need
for separate inside or outside flange
clamps, and field modification.
•
Unique clamp mounting provides
greater cable capacity and working
area within the tray by reducing inter-
nal clamp obstruction.
•
Exclusive TCCD double conduit
clamps conserve space where multiple
cables exit the tray at one location.
•
Only four clamps fill needs for all
conduit sizes from 1/2” thru 4”.
•
Fewer catalog numbers reduce job-
site inventory and the chances of er-
rors and confusion.
Features: TCGC
•
Meets requirements of NEC Articles
250.4(A)(3) and 392.6(J) for grounding and
bonding.
•
Quick and easy installation—low in-
stalled cost. No drilling or special tools
required.
•
Accommodates solid (where suit-
able) or stranded aluminum or copper
grounding conductors from #6 to 2/0.
•
Setscrew bonds the clamp to the
tray and another setscrew securely
attaches the grounding conductor to
the clamp—outstanding pull-out and
vibration resistance.
