Mechanical Connector For Aluminum And Copper

This Burndy mechanical connector accepts stranded copper conductors from 4 AWG up to 500 kcmil and is also rated for aluminum wire. A single 3/8 inch stud hole with a 0.42 inch diameter provides the mounting point for one conductor termination.

Hex Socket Head Simplifies Installation

The hex socket head allows the installer to tighten the connection with a standard hex driver rather than a specialised crimping tool. This reduces the number of tools required on site and speeds up termination work in commercial electrical panels.

Aluminum Body Rated For 600 Volts And 194 Degrees F

The aluminum body measures 2.81 inches overall with a 1.5 inch tongue length, 1.52 inch tongue width and 0.31 inch tongue thickness. These dimensions suit standard lug mounting patterns while the 600 volt and 194 degree F ratings cover typical commercial power distribution environments.

Questions about this item

Will the aluminium body or the hex-socket hardware need replacement if the lug runs at 194 °F continuously?

The lug is rated for a maximum operating temperature of 194 °F; staying at or below that limit avoids thermal degradation of the aluminium body and the hex-socket hardware.

What stops me from using a conductor larger than 500 kcmil in this lug?

The connector is specified for stranded copper up to 500 kcmil; exceeding that size would exceed the tongue width of 1.52 in and the single-hole design.

How much heat does the lug add when it carries full-rated current all day?

With a 600 V rating and aluminium construction, the lug itself adds minimal resistive heat; the 194 °F ceiling is the limiting factor for sustained full-load operation.
