An electrical connector adapted for portable power distribution systems and other applications in various embodiments includes a versatile lug which may be selectively and repeatedly coupled to a stranded or other conductor and mounted and re-mounted on a bus bar or other mounting surface via a variety of attachment features on the lug. The lug offers numerous ways to attach it to a power bus and is designed for thousands of installations and re-installations each requiring the appropriate torque on the connector rather than a few such installations for which a known connector is designed and rated. The attachment features included in various embodiments of the lug connector allow for horizontal, vertical, side by side and edge clamping among other mounting configurations.
