Product Specification

Mechanical Connector System
1 Scope
This specification establishes the materials, design,
marking, installation, inspection, and performance
requirements of ILSCO’s mechanical connector system.
Product families included within the mechanical wiring
system are solderless lugs, splices, taps, clamps, lay-in
connectors, split bolts, and neutral bars made from
aluminum, copper, zinc, or bronze.
2 Materials

All mechanical connections shall use ILSCO’s
mechanical wiring connectors.

2.2

Connectors manufactured from aluminum shall be
in compliance with ASTM B108 or B221.

2.3

Connectors manufactured from copper shall be in
compliance with ASTM B124, B152, or B301.

2.4

Connectors manufactured from bronze shall be in
compliance with ASTM B62, B98, or B505.

2.5

Connectors manufactured from zinc shall be in
compliance with ASTM B86.

2.6

Aluminum connectors shall be plated with electrotin plating in compliance with ASTM B545 and
B571.

2.7

protective plating shall be plated with electro-tin
plating in compliance with ASTM B-545 and B571
or bright dipped.

3.3

Copper and bronze connectors shall be rated for
copper conductors at 90-deg C.

3.4

Connectors shall be range taking; accepting
various conductor sizes.

3.5
