Splicer blocks
Catalog number example:
16204-3 is a 3-pole 16204
Where:
•
The prefix “16204” defines the block’s lineside
and loadside characteristics (i.e., conductor port
per pole that accepts 2/0 - #14 Cu, or 2/0 - #12
Al conductors).
•
The suffix “3” in this example defines this as a
three-pole block.
•
See the catalog number tables for details on the
available lineside/loadside characteristics.
How to order:
From the catalog number tables, select the catalog
number that defines the desired lineside/loadside
port and conductor characteristics.
Catalog symbols:
Add to the catalog number the suffix that defines
the desired pole configuration. Note, you must
select from the available number of poles for
each catalog number. These appear in the second
column of the catalog number tables.

Description:
Bussmann™ series splicer blocks allow for
increasing or decreasing wire size within a circuit
to accommodate different connections from the
power source to the branch load.
Splicer blocks are available for wire sizes up to 500
kcmil and amp ratings up to 760 A.
They are UL® Recognized to UL 1059 and rated for
use in UL 508A industrial control panels.
These blocks are factory configured from 1- to
4-poles (catalog number dependent) with optional
covers (order covers separately).
* Maximum SCCR contingent upon the application of an
upstream current-limiting overcurrent protective device.
See table for fusing requirements.

* 75°C wire (higher temperature rated wire acceptable with appropriate derating). Using a ferrule on a stranded conductor requires a correctly sized UL Listed ferrule
(customer supplied) applied according to the manufacturer’s specifications. Ferrule ratings apply to copper wire only.
** Not covered by CSA certification.
† See table below for the tested upstream overcurrent protective devices necessary for achieving this SCCR.
†† Torque rating for dual wire and ferrule application is 30.5 N•m (270 Lb-in).

Ferrule terminal application
Dual wire port application
•
•
Rated for dual wire port application to increase the possible
number of lineside and loadside connections. E.g., 16303-1 can
accept two wires into the lineside port (1/0 - #6 Cu/Al) and two
wires per port (2 connections per pole total) on the loadside lug
(1/0 - #6 Cu/Al).
Dual wire applications are only viable when using two wires of
the same size, stranding, and insulating and conductor material in
the same port.
•
Bussmann series splicer blocks are rated for use with UL Listed
ferrules (see catalog number table for details). Ferrule ratings
apply to copper wire only.
•
Ferrule applications allow for the use of a broader range of
conductor stranding and simulate a more efficient, solid wire
connection with the PDB terminal port.
•
Always use UL Listed ferrules in accordance with the
manufacturer’s specifications and instructions.
