Mechanical Lug 350 kcmil

The Blackburn BTC3511 is a copper mechanical lug rated for a single conductor up to 350 kcmil. It accepts stranded copper wire from 1/0 AWG to the maximum size and mounts with one 13/32 inch hole. The slotted head allows standard tool engagement for field installation.

Single Conductor Termination

This lug suits installers terminating one copper feeder per connection point on busbar or equipment pads. It does not suit multi-conductor taps or applications requiring two-hole NEMA spacing for vibration resistance. Buyers needing aluminium conductor compatibility or a higher temperature rating should select a different connector.

Sustained Load Behaviour

The copper body operates continuously at up to 194 degrees Fahrenheit and 1,000 volts maximum. Tongue dimensions of 1.31 by 1 by 0.19 inches provide stable contact pressure across thermal cycles. The single-hole mount keeps alignment simple but offers less resistance to mechanical rotation than dual-hole patterns.

Questions about this item

What wire gauge must I have for the BTC3511 lug to accept the conductor?

The lug accepts stranded copper from 1/0 AWG up to 350 kcmil, so your wire must fall within that range.

Will the single 13/32 in stud hole line up with the bus bar I already use?

Yes, the lug has one hole of 0.41 in diameter on 1.31 in tongue length, matching a 13/32 in stud pattern.

How can I confirm the connection is sound after torquing the slotted head?

Verify the copper body sits flat, the conductor shows no strand damage, and the assembly does not exceed 194 °F under load.
