Why Contractors Choose It
- Listed for the applications on the Arlington spec sheet. No jurisdictional surprises at inspection.
- Service-mast geometry and fastener detail that satisfies the local utility's connection standard, not just the bonding inspector.
- Maple Electric Supply, a Canadian-owned stocking dealer, 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
- Service mast assemblies must comply with utility supply authority requirements and CEC 6-112. Mast height and bracing per local utility standards.
-
Primary code reference: CEC Section 6-112 (Service Equipment); CEC 26-700 (Outdoor).
- 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 Mast Parts line. Most of them are small and avoidable when the right SKU and accessory get pulled at the counter.
- Skipping utility approval before install
- Using residential mast on commercial amperage
- Forgetting the weatherhead at the top
- Not bonding the mast per CEC 10

Frequently Asked Questions
-
Is the Arlington WC1001 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.
-
What service amperage does this support (100A, 200A)?
Varies by configuration. Check the WC1001 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.
-
Conduit trade size?
The WC1001 is a 1" trade-size fitting.
-
Galvanized steel or aluminum?
The WC1001 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.
-
Includes weatherhead, straps, and entrance components?
Confirm against the published Arlington WC1001 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.
-
Utility-approved for service entrance use?
Maple Electric Supply can pull the WC1001 spec sheet on request. Answers here depend on the specific configuration and the listed conditions of use. Anything that affects code compliance should come straight from the manufacturer's current published documentation.
