10 T90/TWN75 · Copper Black Stranded 300 M Reel

What this product is for

This is a single-conductor #10 AWG stranded copper T90 building wire for installation in raceways and cable trays where a 600 V, 90 deg C insulated conductor is specified. The black insulation makes it suitable for phase identification where permitted by code and project standards.

Use for

Use for branch circuits, feeders, control wiring runs, and panel or equipment connections in conduit systems. Stranded construction is commonly chosen where easier pulling and better flexibility are needed compared with solid conductor.

Avoid for

Do not use as flexible cord, portable cable, or where a cable assembly such as AC90, TECK90, or NMD90 is required. Do not size conductors by rule of thumb alone; conductor sizing, overcurrent protection, and derating must follow the Canadian Electrical Code and equipment markings.

Best for

Best for electricians and contractors needing a 300 m (984 ft) pull box or spool of black stranded #10 copper building wire for conduit work in commercial, industrial, and larger residential projects.

Installed in

Typically installed in EMT, rigid conduit, PVC conduit, or cable tray systems in service, feeder, and branch-circuit applications, subject to code-compliant installation methods.

Why this product exists

T90 building wire provides a high-temperature insulated single conductor for raceway-based wiring methods used across Canada. A stranded #10 conductor is commonly selected when installers want easier handling on longer pulls and cleaner routing into boxes, gutters, and equipment.

Compared with similar products

Compared with solid #10 T90, this stranded version is typically easier to pull and terminate in tighter layouts. Compared with cable assemblies such as NMD90, this product is intended for conduit or tray wiring methods rather than exposed cable runs through framing. As a typical trade rule, #10 AWG copper is commonly used on 30 A circuits, but final circuit design depends on insulation rating, termination temperature limits, bundling, ambient temperature, and local code.
