Burndy C11N Cast Bronze Ground Clamp, Cable to Water Pipe or Tube

The Burndy C11N is a cast bronze ground clamp engineered to connect grounding cable to a water pipe or copper tube, providing a secure mechanical bonding point for electrical grounding systems. Part of Burndy's copper mechanical grounding connector line of water pipe ground clamps, this clamp accommodates 10-2 AWG conductor cable and fits 1/2" - 1" water pipe or copper tube, with a pipe clamp screw torque rating of 50 in-lb for a consistent, code-compliant connection. Built from durable cast bronze for long-term corrosion resistance, the C11N is a dependable choice for grounding electrode conductor terminations in residential, commercial, and industrial electrical installations where a solid mechanical bond to a metallic water pipe is required.

Key Features

  • Pipe/Tube Range: Fits 1/2" - 1" water pipe or copper tube for versatile grounding electrode connections.
  • Durable Construction: Cast bronze (bronze alloy) body resists corrosion for long service life on water pipe grounding connections.
  • Conductor Range: Accepts 10-2 AWG grounding cable for compatibility with common grounding conductor sizes.
  • Torque Rating: Pipe clamp screw is rated to 50 in-lb, supporting a secure, consistent mechanical connection to the pipe or tube.
  • Cable-to-Pipe Design: Purpose-built to bond a grounding cable directly to a water pipe or copper tube rather than to another cable or a ground rod.
  • Mechanical Grounding Connector: Classified within Burndy's copper mechanical grounding connector family as an LC-style water pipe ground clamp.

Burndy C11N – Frequently Asked Questions

1) What wire sizes does the C11N water pipe ground clamp accept?
It takes 10 AWG through 2 AWG copper conductor, solid or stranded. That covers the usual grounding electrode conductor sizes on residential and light commercial services, including #6 and #4 copper. If your GEC is larger than 2 AWG, the C11N is the wrong clamp.
2) Can I use the C11N to attach a ground wire to a ground rod instead of a pipe?
No. The C11N is a cable-to-water-pipe clamp, built to bond a grounding conductor to a water pipe or copper tube, not to a driven ground rod and not cable to cable. For a rod you need a rod clamp sized to the rod diameter.
3) What torque should I use on a Burndy C11N ground clamp screw?
The pipe clamp screw is rated to 50 in-lb. Use a torque screwdriver rather than feel, since an under-torqued bond on a grounding electrode conductor is the usual inspection failure and over-torquing a cast bronze body can crack it.
4) Is the Burndy C11N bronze or steel, and will it hold up in a damp crawlspace or mechanical room?
Cast bronze alloy throughout. Bronze on copper pipe keeps the two metals close enough to avoid the galvanic problems you get bolting steel hardware to copper, which is why it is the standard body material for water pipe grounding in basements, crawlspaces and service entrances.
5) Is the C11N a mechanical connector or does it need to be crimped or exothermically welded?
Mechanical. It bolts on and clamps down, no crimping tool, no dies and no exothermic welding kit, which is why it suits retrofit grounding upgrades and service work where you cannot bring a press to the pipe. The trade-off is that a mechanical bond must be accessible for inspection, unlike a welded connection.
6) Where can I get the manufacturer spec sheet for the Burndy C11N?
Burndy publishes a spec sheet for the C11N at hubbellcdn.com/specsheet/BRDY-C11N-SPEC-EN.pdf, which is the document to hand an inspector or attach to a submittal package.
