Burndy QGFL39B1 Mechanical Copper Bar Tap Connector

The Burndy QGFL39B1 is a mechanical copper bar tap connector engineered for substation bus bar and tap connections. Manufactured from copper for reliable conductivity, this connector accommodates a 350-750 kcmil single-conductor wire range, making it well suited for heavy-duty substation and industrial power distribution applications where a dependable, code-compliant mechanical copper-to-copper tap connection is required. Electricians and substation crews rely on connectors like the QGFL39B1 to join copper conductors directly to copper bus bar taps without the specialized tooling that compression-style connectors typically demand, helping keep installation and maintenance work efficient on critical electrical infrastructure.

Key Features

  • Wire Range: Accepts 350-750 kcmil copper conductors, supporting high-capacity substation tap connections across a wide range of large-gauge copper cable sizes.
  • Copper Construction: Solid copper body construction delivers excellent electrical conductivity, minimizes connection resistance, and provides long-term durability in demanding substation environments.
  • Mechanical Connection: Mechanical-style connector design allows for straightforward field installation onto copper bar taps without the specialized compression tooling or dies required by crimp-style connectors.
  • Single-Conductor Configuration: Single-port design is built for one copper conductor termination per connector, simplifying bar tap installations and keeping wiring layouts clean.
  • Substation-Grade Design: Purpose-built for substation bar tap applications where dependable, secure copper-to-copper connections are essential to system reliability.
  • Bar Tap Application: Designed specifically for tapping onto copper bus bars in substation and heavy industrial power distribution settings, providing a direct, low-resistance electrical path.
  • Field-Serviceable Design: Mechanical connection style supports straightforward inspection, re-torquing, and maintenance during scheduled substation servicing.

Burndy QGFL39B1 – Frequently Asked Questions

1) What wire sizes does the Burndy QGFL39B1 bar tap connector accept?
The QGFL39B1 takes a single copper conductor from 350 kcmil through 750 kcmil. One port, one conductor, so if you are landing two cables at the same bus point you need two connectors or a dual-port body. Anything below 350 kcmil is outside the range and will not seat properly in the conductor barrel.
2) Can I use the QGFL39B1 on an aluminum bus bar or with aluminum cable?
No. The QGFL39B1 is a copper-bodied connector built for copper-to-copper tap connections on copper bus bar. Aluminum cable or aluminum bus needs a connector rated AL9CU or an aluminum-bodied tap; putting bare aluminum into a copper-only body sets up a dissimilar-metal joint you do not want in a substation.
3) Do I need a crimp tool or dies to install a Burndy QGFL39B1?
No dies, no hydraulic crimper. It is a mechanical connector, so it lands with a wrench on the setscrew hardware. That is the practical reason crews pick it for bus bar taps out in a yard where hauling a compression head and the right die set is a nuisance. It also means the joint can be inspected and re-torqued later instead of being cut out.
4) Mechanical bar tap connector or compression connector for a substation bus tap?
Mechanical, like the QGFL39B1, is the choice when you want a joint you can open, inspect, and re-torque on a maintenance cycle, and when you do not want to bring compression tooling and dies to the work point. Compression is the choice for a permanent, tamper-resistant termination where nobody intends to service the joint again. Both are used on substation bus; the deciding factor is usually maintenance policy and what tooling the crew carries.
5) What is the exact Burndy part number to order for a 500 kcmil copper bus tap?
Burndy QGFL39B1. That single catalog number covers the whole 350 to 750 kcmil copper range, so 500 kcmil falls mid-range rather than at an extreme of the port. There are no finish or size options to specify, it is ordered as the one model.
6) Is the QGFL39B1 suitable for indoor switchgear or only outdoor substations?
Its intended work is bus bar tap connections in substations and heavy industrial power distribution, which covers both yard bus and indoor industrial distribution bus. What the connector cares about is the metal: copper conductor into a copper bar. Environment aside, confirm the bar geometry at your tap point suits a mechanical bar tap body before ordering.
7) Where do I get the installation torque and dimensional data for the Burndy QGFL39B1?
Burndy publishes a spec sheet for the QGFL39B1 at hubbellcdn.com (document BRDY-QGFL39B1-SPEC-EN). That is the source for the manufacturer's dimensions and tightening values, which matter because a mechanical tap joint only performs to spec if the hardware is torqued to the published figure.
