SEPCO 10BG Zinc Die-Cast Ground Clamp for 1/2 - 1-Inch Pipe and Conduit
The SEPCO 10BG Ground Clamp is a die-cast zinc grounding fitting that creates a secure, low-resistance bond between a grounding conductor and a metal pipe or conduit run. Sized to fit pipe and conduit from 1/2 - 1-Inch, the clamp is available in two wire range options - 8-2 AWG and 10-2 AWG - so installers can match the clamp to grounding electrode conductors and bonding jumpers from 10 AWG up to 2 AWG. Electricians and maintenance crews rely on this single clamp body for grounding rods, metallic water pipes, and metal conduit systems on residential and light commercial jobs.
Key Features
- Trade Size: Fits pipe and conduit from 1/2 - 1-Inch, covering the most common residential and commercial grounding points in a single clamp body.
- Durable Construction: Die-cast zinc body resists corrosion and provides long-term mechanical strength at the ground connection, standing up to repeated tightening and field handling.
- Wire Range Options: Offered in 8-2 AWG and 10-2 AWG wire range options, accommodating grounding electrode conductors and bonding jumpers from 10 AWG up to 2 AWG depending on the option selected.
- Ground Clamp Design: Purpose-built clamp geometry creates a secure, low-resistance bond between the grounding conductor and the pipe or conduit, supporting reliable fault-current paths.
- Versatile Fit: A single clamp covers multiple pipe diameters within its 1/2 - 1-Inch range, reducing the number of part numbers electricians and distributors need to stock and quote.
- Model 10BG: Identified under SEPCO's 10BG designation for straightforward specification, ordering, and reordering across projects.

SEPCO 10BG – Frequently Asked Questions
1) Which wire range do I order for a #6 copper grounding electrode conductor?
Either option takes #6. The SEPCO 10BG ground clamp comes in two wire ranges: 8-2 AWG (model 10BG) and 10-2 AWG (model 10BR). Both cover 6 AWG. Pick 10-2 AWG if you also need to land smaller 10 or 8 AWG bonding jumpers, and 8-2 AWG if your smallest conductor on the job is 8 AWG.
2) Can a zinc die-cast ground clamp be used on a buried or outdoor ground connection?
The 10BG is a die-cast zinc body, which resists corrosion and holds up to repeated tightening in service work, but zinc die-cast clamps are normally specified for above-grade connections. For a driven ground rod where the clamp sits in or near the earth, a bronze rod clamp is the usual choice, such as the nVent CADDY CP Series silicon bronze ground rod clamp.
3) What is an equivalent to the SEPCO 10BR ground clamp for a 10-2 AWG copper grounding conductor?
The SEPCO 10BG clamp family covers a 10-2 AWG wire range under part number 10BR, with a zinc die-cast body sized for 1/2 to 1 inch pipe and conduit. A comparable option for the same conductor range is the nVent CADDY BGC-1 ground clamp, rated for a 10-2 AWG copper conductor range and supplied in a pack of 100. The SEPCO is ordered as an individual clamp by wire range option, while the CADDY BGC-1 comes as a 100-piece pack, so the choice often comes down to how many connections the job needs.
4) Should I use the SEPCO 10BG clamp or a bronze ground rod clamp for bonding to a driven ground rod?
The SEPCO 10BG is a zinc die-cast clamp sized for 1/2 to 1 inch pipe and conduit, so it suits metallic water pipe and metal conduit grounding points as well as grounding electrode conductor connections. If the connection is specifically to a driven rod, the nVent CADDY CP Series silicon bronze ground rod clamp is purpose-built for rods and uses a silicon bronze body rather than die-cast zinc. Pick by what the conductor lands on: pipe and conduit runs favor the 10BG clamp body, while a dedicated rod clamp is designed around the rod itself.
5) What is the difference between the SEPCO 10BG and the nVent CADDY BGC-1 ground clamp?
Both land small grounding conductors, but they are bought differently. The SEPCO 10BG is sold as a single clamp with a choice of 8-2 AWG or 10-2 AWG wire range and fits 1/2 to 1 inch pipe and conduit. The nVent CADDY BGC-1 is a 10-2 AWG copper conductor clamp supplied in packs of 100, which suits a crew stocking a truck or roughing in a large job.
6) Is the 10BG the right clamp for bonding metal conduit back to a panelboard?
Yes, that is one of its intended uses. The clamp creates a low-resistance bond between a grounding conductor and a metal conduit or pipe run, and it is used for panelboard and service equipment grounding, water pipe and conduit bonding, and grounding electrode conductor connections on residential and light commercial work.
7) My grounding conductor is 4 AWG - does the nVent CADDY BGC-1 work, or do I need the SEPCO clamp?
The nVent CADDY BGC-1 is listed for a 10-2 AWG copper conductor range, which brackets 4 AWG. The SEPCO 10BG clamp also offers an 8-2 AWG wire range option alongside its 10-2 AWG option, either of which accepts 4 AWG. Both will take the conductor; the SEPCO body is zinc die-cast and sized to 1/2 to 1 inch pipe and conduit, so confirm the pipe diameter at the connection point before choosing.
8) Can I use one part number across a multi-family grounding retrofit instead of stocking several clamps?
That is the practical reason to standardize on the 10BG. A single clamp body covers every pipe diameter from 1/2 to 1 inch, so a property maintenance crew or distributor carries one line item for most service upgrades and grounding repairs rather than one clamp per diameter. You would still choose between the 8-2 AWG and 10-2 AWG wire range depending on the conductors in the buildings.
9) For a multi-family service upgrade with many ground connections, do I stock the SEPCO 10BG or the CADDY BGC-1?
Both cover a 10-2 AWG conductor range. The nVent CADDY BGC-1 is sold as a pack of 100, which suits a crew making the same connection repeatedly across many units. The SEPCO 10BG clamp body is ordered by wire range option - 8-2 AWG or 10-2 AWG - and covers 1/2 to 1 inch pipe and conduit in one clamp, which lets you carry fewer part numbers when pipe sizes vary from building to building.
