Panelboard stack lug · 6 AWG to 300 kcmil · dual rated aluminium · Ilsco PB2-300

What this product is for

The Ilsco PB2-300 is a mechanical panelboard stack lug used to terminate copper or aluminium conductors in panelboards and similar power distribution equipment. It is built for conductor ranges from 6 AWG to 300 kcmil where a dual-rated lug is required.

Use for

Use for panelboard terminations, replacement lugs, retrofit work, and distribution equipment where a 2-port mechanical lug with a 5/16 in stud connection is specified. Commonly used by electricians and panel shops in commercial and industrial installations.

Avoid for

Avoid using where the equipment requires a different lug pattern, a different stud size, a higher conductor range, or a connector type not listed for the application. Always confirm conductor material, wire range, and equipment approval before installation.

Best for

Best for service and distribution work where one lug must accept either copper or aluminium conductors and where space in the panelboard calls for a compact stack lug format.

Installed in

Typically installed in panelboards, switchboards, control panels, OEM assemblies, and retrofit distribution equipment. Product dimensions are approximately 3 in L x 1 in W x 2 in H (about 76 x 25 x 51 mm).

Why this product exists

This lug provides a field-installable termination option for a wide conductor range without changing to a compression connector. The dual-rated design helps simplify stocking when jobs may use either copper or aluminium conductors.

Compared with similar products

Compared with single-conductor lugs, this model provides 2 ports. Compared with copper-only lugs, it is dual rated for copper or aluminium conductors. As a buying check, electricians should match the wire range, stud size, and equipment listing rather than choosing by conductor size alone.
