Burndy GB34-300-500 Ground Connector

Burndy GB34 is a mechanical grounding connector designed to bond a 300 to 500 kcmil copper conductor to a 1/4" thick grounding bar, using a 1/2" stud. The copper-alloy body pairs with silicon bronze hardware and incorporates a built‑in separation feature that keeps the cable from contacting the bar, delivering a reliable ground path. This UL467‑listed device is intended for direct burial in concrete or ground and supports one‑wrench installation for straightforward field work. It measures 2-3/8" wide and 3" tall, with compatibility for a 1/4" thick bar, and is specified for 300–500 kcmil conductors. Typical applications include grounding large conductors by connecting them to a ground bar in electrical gear or service equipment, ensuring a secure, code‑compliant bond. The installation torque is specified at 480 in‑lb to achieve proper clamping force.
