* 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).

Dual wire port application
•
Ferrule terminal 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.
