Connectors & Grounding — Blackburn® Mechanical Connectors
Service Post Connectors
For grounding of steel structures,
fence posts or transformers using
one or two cables.
Service Post Connectors
• For copper-to-copper connections
• For tapping one or two cables from bus bar
• Hex design bolts machined from
high-conductivity bronze alloy
• Nuts and pressure bars cold-formed
from high-strength copper or copper alloy
• Available in sizes for #12 – 500 kcmil
stranded and #12 – #2 solid copper conductor
• Available in both single- and
double-conductor versions
•UL® 486A and UL® 467 Listed
Blackburn Service Post Connectors are designed for
applications including steel structure, fence post or
transformer grounding involving one or two cables.
They can also be used to tap one or two cables from
bus bar.
Bolts used in the Service Post Connectors are
machined from high-conductivity bronze alloy
while the nuts are cold-formed from high strength,
corrosion-resistant copper alloy. Pressure bars are
copper through 4/0 size, while copper alloy is used
for 350 kcmil size and above.

Conductors that can be used with the Power Distribution Blocks —
number, cross-section and type.
• Requirements of a specific apparatus may
restrict the number of conductors
• After installation, check that all conductors
are pressed into a connection
• Usually a maximum of three adjacent
standard cross-sections in one space
• The nominal current of the power
distribution blocks must not be exceeded
• In general, the conductors connected
to one conductor space of a connector
must be of the same type
• According to some installation standards,
each incoming and outgoing protection and
neutral conductor in a panel must have
its own separate power distribution blocks
• Table values require careful installation
• We recommend use of ferrules when using
fine-stranded conductors

Connectors & Grounding — Blackburn® Mechanical Connectors
Anti-Rotational Connectors
“No-turn” design keeps
connector securely in place —
even under vibration.
Anti-Rotational Connectors
Blackburn ® Anti-Rotational Connectors are designed with a rib on
the bottom that keeps the connectors from turning, so there’s no need
to apply excessive torque and there’s no danger of loosening connectors.
The unique “no-turn” rib provides a secure connection that eliminates
the conductor pinching that results from connector movement.
The “no-turn” design solves a unique problem for electricians and
installers. Larger conductors tend to get damaged in over-torque
conditions, and connectors are prone to loosen in applications where
there is vibration, such as motor loads.
Inspectors and local standards boards are requiring electricians
and installers to make provisions to eliminate these conditions,
and Blackburn ® Anti-Rotational Connectors are the solution.
• Unique bottom rib keeps connector from turning
• Eliminates the need for excessive torque, which
can damage large conductors
• Prevents connector loosening, even in heavyvibration applications
