Best For
Common scopes where the Arlington GBB5 (and the rest of the Grounding line) earns its place on the spec. Not an exhaustive list, but a fast read on whether this is the right family for your application before you go deeper on the cut sheet.
- Service-entrance grounding
- Equipment bonding
- Panel ground-bar terminations
- Rod-clamp connections to ground rods
Why Contractors Choose It
- Listed for the applications stated on the Arlington spec sheet, so there are no jurisdictional surprises at inspection.
- Listed conductor ranges, dual-rated copper/aluminum where called for, and clamp geometry built for the rod or busbar it bonds to.
- Distributed by a Canadian-owned stocking dealer. Maple Electric Supply ships from Ontario, so the SKU lands on site without cross-border duty calcs or week-long customs holds.
- Backed by Arlington's North American manufacturing footprint. It's the same part number you've already spec'd on prior jobs, with the same listings.
- Replacement and add-on availability runs through a Canadian supply channel, so short-notice job sites can pull additional units without re-engineering the order.

Installation Notes
- Bonding and grounding equipment must be listed for the conductor size per CEC Section 10. Grounding clamps must be of the type and size suitable for the bond/conductor.
-
Primary code reference: CEC Section 10 (Grounding & Bonding); CEC 10-806 (Ground Clamps).
- Verify the Arlington listing on the current spec sheet matches your local AHJ's adopted code edition. Provincial amendments to the CEC can override the federal base text.
- Confirm trade size, mounting style, and accessory pairing against the project drawings before ordering in volume. Maple Electric Supply's counter staff can pull the cut sheet on request.
- Installation must be completed by a qualified electrician where required by local code; the homeowner / unlicensed scope is narrower in Ontario than in several US jurisdictions.
Common Mistakes to Avoid
Patterns we see on returns, callbacks, and inspection re-visits around the Grounding line. Most of them are small and avoidable when the right SKU and accessory get pulled at the counter.
- Using indoor-only clamps on outdoor ground rods
- Mixing copper and aluminum without dual-rated clamps
- Skipping the bonding bushing on metallic conduit
- Forgetting the listed conductor size range

Frequently Asked Questions
-
Is the Arlington GBB5 UL and/or CSA listed?
Arlington components are listed for the applications stated by the manufacturer. Always verify the listing on the product's spec sheet against your jurisdiction's adopted code.
-
Is this part made in the USA?
Arlington Industries manufactures the bulk of its catalog in the United States. Confirm origin on the current spec sheet if it matters for your project.
-
Conductor size accepted (#14 AWG to 4/0)?
Varies by configuration. Check the GBB5 datasheet for the exact dimensions, ratings, and accessory list before ordering in volume. Arlington updates spec sheets periodically, so spec the live version from the manufacturer's site for the current job.
-
Direct burial rated?
The GBB5 datasheet is the authoritative source on this. Arlington publishes torque specs, listed conductor ranges, and accepted accessories per part number, and those values shift between revisions even when the SKU stays the same.
-
Listed for use with copper, aluminum, or both?
Confirm against the published Arlington GBB5 cut sheet; values shift between configurations even inside the same family. Maple Electric Supply can email a current copy on request and flag any recent revisions that changed listed ratings.
-
Pipe size accepted (for pipe-attached clamps)?
Maple Electric Supply can pull the GBB5 spec sheet on request. The answer depends on the specific configuration and the listed conditions of use, and anything that affects code compliance should come straight from the manufacturer's current published documentation.
-
UL / CSA marked?
Refer to the GBB5 product page on Arlington's site or contact Maple Electric Supply for a copy of the current spec sheet with all listed ratings. Generic family-level guidance is a starting point, but the SKU-level sheet is what the inspector will reference.
