SEPCO RBC-50 Bronze Alloy Direct Burial Ground Clamp

The SEPCO RBC-50 is a Bronze Alloy Direct Burial Ground Clamp engineered to create a secure, corrosion-resistant bonding connection between a grounding conductor and pipe, rebar, or ground rod. Featuring a patent pending design, this clamp accommodates 1/2 - 1-Inch pipe, 3/8 - 1-Inch rebar, and 1/4 - 1-Inch rod, while accepting conductors from 10-AWG Solid to 2-AWG Stranded. Built for below-grade installation, the RBC-50 delivers a dependable grounding connection for electrical systems that demand long-term underground reliability, protecting the integrity of the ground path against soil moisture, chemical exposure, and years of buried service.

Key Features

  • Pipe Range: Accommodates 1/2 - 1-Inch pipe for versatile grounding electrode connections.
  • Rebar Range: Fits 3/8 - 1-Inch rebar, suited for Ufer-style concrete-encased electrode grounding.
  • Rod Range: Accepts 1/4 - 1-Inch ground rod for standard driven-rod grounding systems.
  • Conductor Range: Terminates 10-AWG Solid to 2-AWG Stranded grounding conductors, covering a wide span of service and equipment grounding wire sizes.
  • Durable Construction: Bronze Alloy body resists corrosion in direct burial and underground environments, maintaining a low-resistance ground path over time.
  • Direct Burial Rated: Engineered for below-grade installation where long-term connection integrity is critical to system safety.
  • Patent Pending Design: SEPCO's proprietary clamp geometry secures a solid mechanical and electrical bond between conductor and electrode.
  • Multi-Electrode Versatility: A single clamp body serves pipe, rebar, and rod electrodes, reducing the number of SKUs an installer must stock.

SEPCO RBC-50 – Frequently Asked Questions

1) Will the SEPCO RBC-50 ground clamp fit 1/2-inch water pipe and a 5/8-inch ground rod?
Both work. The RBC-50 clamps pipe from 1/2 inch to 1 inch and rod from 1/4 inch to 1 inch, so a 1/2 inch metallic water pipe electrode and a standard 5/8 inch driven rod are both inside its range. One clamp body covers pipe, rod, and rebar, which is why electricians carry it instead of three separate parts.
2) Can I use the RBC-50 on rebar for a Ufer ground?
Yes. The RBC-50 accepts rebar from 3/8 inch through 1 inch, which covers #3 through #8 bar, and it is a direct burial clamp, so it can be left encased or buried at a concrete-encased electrode connection.
3) What size grounding conductor can I land in the SEPCO RBC-50?
It terminates 10 AWG solid up through 2 AWG stranded. That spans the typical equipment grounding conductor sizes and the 4 and 2 AWG grounding electrode conductors used on most residential and light commercial services. Anything larger than 2 AWG needs a bigger clamp.
4) Is this ground clamp OK to bury, or does it have to stay accessible?
The RBC-50 is built for below-grade use. The bronze alloy body resists corrosion from soil moisture and chemical exposure, so it can be buried at the rod, pipe, or rebar connection rather than being brought up into an accessible box.
5) If I only need to bond a conductor to a driven ground rod, is there a simpler clamp than the SEPCO RBC-50?
Yes. The nVent CADDY CP Series is a silicon bronze ground rod clamp, built specifically for the rod connection and nothing else. The RBC-50 is a multi-electrode clamp: one bronze alloy body serves 1/2 to 1-inch pipe, 3/8 to 1-inch rebar, and 1/4 to 1-inch rod. If every connection on the job is a driven rod, the single-purpose CP Series clamp is the narrower choice; if the job mixes rod, rebar, and water pipe electrodes, the RBC-50 covers all three from one part number.
6) What is the closest alternative to the SEPCO RBC-50 for terminating 10 AWG to 2 AWG grounding conductors?
The nVent CADDY BGC-1 ground clamp covers a 10-2 AWG copper conductor range, which lines up with the RBC-50's 10-AWG solid to 2-AWG stranded conductor range. The difference is in what each clamps onto: the RBC-50 is a bronze alloy body that takes 1/2 to 1-inch pipe, 3/8 to 1-inch rebar, and 1/4 to 1-inch rod, and is built for direct burial. The BGC-1 is supplied in packs of 100, so it suits crews placing a large quantity of conductor terminations at once.
7) Can I use an nVent CADDY ground clamp in place of the SEPCO RBC-50 on a Ufer rebar connection?
Check the electrode range before you do. The RBC-50 is specified for 3/8 to 1-inch rebar and is called out for Ufer concrete-encased electrode grounding. The nVent CADDY CP Series is a silicon bronze ground rod clamp, and the BGC-1 is specified by its 10-2 AWG copper conductor range rather than a rebar range, so neither is described for rebar the way the RBC-50 is. For a rebar stub coming out of a footing, the RBC-50 is the one with the stated rebar capacity.
8) I need to bond to a 1-inch water pipe. Will the nVent CADDY CP Series work, or do I need the SEPCO RBC-50?
For pipe, go with the RBC-50. It is sized for 1/2 to 1-inch pipe, which covers a 1-inch water service as a grounding electrode connection. The nVent CADDY CP Series is a ground rod clamp, so it is not the part for a pipe electrode. The RBC-50 also accepts 10-AWG solid through 2-AWG stranded conductors, which spans typical service and equipment grounding conductor sizes on that connection.
9) How does the SEPCO RBC-50 compare to the nVent CADDY CP Series on material for buried grounding work?
Both are bronze-family castings. The RBC-50 body is bronze alloy and is rated for direct burial, where it has to hold a low-resistance path through soil moisture and chemical exposure. The nVent CADDY CP Series is a silicon bronze ground rod clamp. The practical difference for a buried connection is coverage: the RBC-50 takes pipe, rebar, and rod, while the CP Series is dedicated to the rod.
10) Why bronze instead of a cheaper ground clamp body?
Bronze alloy is what makes burial practical. A buried connection sits in wet, sometimes aggressive soil for the life of the building, and a corroding joint raises resistance in the ground path. The RBC-50's bronze body is chosen to hold a low-resistance bond underground over years of service.
