Burndy BIBD-250-4 N Insulated Bonding Lug Connector

Burndy UNITAP BIBD2504 2-Sided Entry Insulated Multi-Tap Connector is a four-port, indoor-rated lug that accepts 10 AWG through 250 kcmil conductors in copper or stranded aluminum (Al/Cu rated). Encased in a clear plastisol-covered aluminum body, it lets you visually verify proper conductor seating while an oxide inhibitor is pre-installed to protect the contact surfaces from moisture and contaminants. Rated for 600 V, this connector is UL Listed to UL 486A-486B and CSA certified for use with code conductors. The four ports are arranged on both sides of the housing to allow entry from opposite directions, enabling compact, two-sided terminations in panels or equipment enclosures. Typical applications include distribution taps and branch connections in control panels, switchgear, and industrial installations where a single unit can replace multiple discrete lugs. Dimensions vary by variant; the standard BIBD2504 unit is listed at roughly 3.91 inches in length in some catalogs, with a width of about 2.64 inches and a height around 2.26 inches, while related MT variants measure longer (about 5.78 inches) but share the same 4-port, 10 AWG–250 kcmil capability and Al/Cu rating.
