Burndy KVS34 2-Bolt Copper Connector, Run & Tap Splice

The Burndy KVS34 2-Bolt Copper Connector is engineered for dependable splicing and tap connections in copper conductor systems where mismatched wire sizes need to meet at a single, secure connection point. This connector family is available in maximum conductor sizes from 350 MCM to 500 MCM, giving electricians and contractors a range of options to match the run and tap conductor sizes on the job while keeping the same solid copper body and 2-bolt mechanical design across the line. Because both the run and tap sides are copper-rated on every option in this family, the KVS34 is intended for all-copper conductor systems rather than mixed copper-to-aluminum applications, and it delivers a secure, low-resistance connection that stands up to the vibration, thermal cycling, and load demands of commercial and industrial electrical work.

Key Features

  • Maximum Conductor Size Options: Choose between 350 MCM and 500 MCM maximum conductor size ratings to match your run and tap conductor requirements without changing connector families.
  • Wide Tap Range: The KVS34 family accepts tap conductors as small as 10 AWG up to the connector's rated maximum, giving installers a wide span of usable tap wire sizes on a single connector body instead of stocking multiple part numbers.
  • Durable Copper Construction: A solid copper body delivers excellent electrical conductivity and long-term corrosion resistance, supporting stable, low-resistance current flow over the life of the installation.
  • 2-Bolt Connection Design: The dual-bolt mechanical connection independently secures the run and tap conductors, providing a firm, vibration-resistant hold and consistent contact pressure across both sides of the splice.
  • Heavy-Gauge Conductor Capacity: Rated up to 500 MCM depending on the option selected, the KVS34 family supports the heavy-gauge copper wiring commonly found in high-load circuits, feeders, and service entrance conductors.
  • Single-Family Versatility: Combining a wide run and tap range across two maximum conductor size options reduces the number of SKUs electrical contractors need to keep on hand for copper splicing and tap work.

Burndy KVS34 – Frequently Asked Questions

1) What conductor sizes does the Burndy KVS34 2-bolt connector accept on the run and tap?
The KVS34 takes run conductors from 400 to 500 MCM and tap conductors anywhere from 10 AWG up to 500 MCM. That spread is what makes it useful for tapping a small branch conductor off a heavy feeder without changing connector part numbers for every combination.
2) Can I use the Burndy KVS34 to connect copper to aluminum conductors?
No. The KVS34 has a solid copper body and both the run and tap sides are copper-rated, so it is meant for all-copper systems. For a copper-to-aluminum transition you need a dual-rated AL9CU connector instead.
3) Is the Thomas & Betts 306 connector an alternative to the Burndy KVS34 for splicing 500 MCM copper?
No. The Burndy KVS34 is a 2-bolt mechanical copper conductor connector that clamps a run conductor of 400 to 500 MCM to a tap conductor of 10 AWG to 500 MCM. The Thomas & Betts 306 is a straight Tite-Bite fitting for 1 inch flexible metal conduit, non-insulated - it terminates raceway to an enclosure and carries no conductor. The word connector covers both, but only the KVS34 makes a conductor-to-conductor splice or tap.
4) Why choose a 2-bolt connector over a single-bolt one for a 500 MCM copper tap?
The dual-bolt design clamps the run and the tap independently, so each conductor gets its own contact pressure and the joint holds up better under vibration and thermal cycling. On heavy feeder conductors in the 400 to 500 MCM range that matters more than on small branch wire, which is where single-bolt bodies are normally used.
5) Can I use a RACO 4734 liquidtight connector where a Burndy KVS34 is specified?
No - they solve different problems. The RACO 4734 is a 1 inch Type B liquidtight multi-position connector in nylon from the SWIVEL-LOK series, used to land liquidtight flexible conduit at a box or enclosure. The Burndy KVS34 is a copper-bodied 2-bolt mechanical connector that joins a 400 to 500 MCM run conductor to a tap from 10 AWG up to 500 MCM. If your drawing calls for a copper tap connection, the 4734 will not make it.
6) I need a junction point for a large copper feeder tap - do I order the KVS34 or a RACO 232MSCM box?
They are ordered together, not against each other. The RACO 232MSCM is a 4 inch square welded box, 2-1/8 inches deep, with a STAB-IT connector and an M bracket - it is the enclosure and mounting for the splice. The Burndy KVS34 is the mechanical connector inside it, taking a 400 to 500 MCM run and a 10 AWG to 500 MCM tap on a 2-bolt copper body. A tap point typically needs both an enclosure and a conductor connector sized to the wire.
7) Is the Burndy KVS34 suitable for grounding and bonding connections?
Yes, grounding and bonding is one of its listed uses, along with panelboard and switchgear wiring, service entrance and feeder connections, and general copper splicing and tap work in commercial and industrial distribution. Keep it to copper conductors only.
8) What is the difference between the Burndy KVS31 and the KVS34?
Both are Burndy KVS series 2-bolt copper mechanical connectors sold under the same copper-bodied, all-copper-system design, and they differ by model designation - KVS31 and KVS34 - with the KVS34 covering a run range of 400 to 500 MCM and a tap range of 10 AWG to 500 MCM. Order by model number to match the conductor sizes at your splice, and note that either is intended for copper-to-copper work rather than copper-to-aluminum.
