Frequently asked questions
Common questions about BURNDY from 3G Electric.
What wire sizes does the BURNDY KS34 split-bolt connector accept?
The KS34 accepts copper conductors from 500 kcmil down to 2/0 AWG and is rated for copper-to-copper connections. It uses a copper body and requires 825 in-lb of torque to terminate and shear the fastening bolt. The connector is not rated for direct burial, so it should be installed indoors or in a dry, protected location. It carries UL 467 and UL 486 A/B listings, along with CSA, ARRA, and EU RoHS compliance. For smaller splices in the same family, the KS203 covers 4 to 8 AWG at 165 in-lb, and the KS17 covers 6 to 8 AWG at the same torque with a direct-burial rating.
Which BURNDY split bolts and grounding connectors are rated for direct burial?
Direct-burial ratings vary by catalog number, so the specific part must be checked. In this line, the KS17 split bolt (6 to 8 AWG copper) and the GRL5 ground rod clamp are both listed for direct burial. The GRL5 is a copper grounding connector that accepts one 10 to 3 AWG stranded copper conductor and fits a 5/8 in rod, and it carries UL Listed Direct Burial and UL 467 ratings. By contrast, the KS34 and KS203 split bolts are not rated for direct burial and are intended for indoor or protected environments. The KC28 grounding split bolt with 5/8"-11 stud is a copper-alloy grounding connector for a single 1 to 4/0 AWG SOL conductor.
What dies does the BURNDY PATRIOT 600 crimping tool use?
The PATRIOT 600 (PAT600LI) accepts W, W-VT, and VT dies in its die head. It delivers 6 tons of force and is rated for copper conductors from 8 AWG up to 600 kcmil and aluminum up to 350 kcmil. The tool is cordless and powered by a Makita 18V LXT battery, which is included, along with a lanyard. The die head provides clearance for tap connections and includes a permanent, functional D3 groove. Because BURNDY compression connectors are die-coded, the die selection must match the specific lug or ferrule being installed — for example, the YA382NFXB lug uses an L99 die code.
What is the BURNDY YA382NFXB compression lug used for?
The YA382NFXB is a two-hole compression lug for stranded copper wire in sizes 500 or 550 kcmil, with a 1/2 in stud size and a long copper barrel. It has no inspection hole and uses an L99 die code for crimping. The barrel outside diameter is 1.25 in and the hole size is 0.56 in. It carries UL and CSA listings. This lug is typically used where a two-hole stud pattern is required for a bolted connection on large stranded copper conductors, such as in switchgear, panel, or equipment terminations. The matching die code should be confirmed against the crimping tool being used.
What is the difference between the BURNDY KC28 and GRL5 grounding connectors?
The KC28 is a copper-alloy grounding split bolt connector with a stud, designed to terminate and secure a single grounding wire. It accommodates 1 to 4/0 AWG SOL conductor and has a 5/8"-11 thread size, with an installation torque of 660 in-lb. The GRL5 is a copper ground rod clamp that connects one stranded copper grounding conductor (10 to 3 AWG) to a 5/8 in rod, and it is rated for direct burial with UL 467 and UL Listed Direct Burial. In short, the KC28 is a stud-mounted grounding split bolt for a single conductor, while the GRL5 is a rod clamp for bonding a conductor to a ground rod.
What is the BURNDY YF25032UIL barrel ferrule specified for?
The YF25032UIL is a Type G non-insulated barrel ferrule for terminating or splicing a single bare copper conductor up to 250 kcmil. It holds one wire and has an overall length of 1.26 in. It is used in industrial power distribution, switchgear, and similar applications where a bare conductor end needs a compression ferrule. The part is supplied individually, and 3G Electric can quote quantities as needed. Because it is non-insulated, it is intended for applications where the connection is enclosed or where insulation is provided separately. Confirm the die and crimping tool match before installation.
