10 T90/TWN75 · Copper White Stranded 300 M Reel

What this product is for

This #10 AWG T90/TWN75 copper building wire is used for raceway and conduit wiring in commercial, industrial, and institutional electrical installations. It is a stranded single conductor with white PVC and nylon insulation on a 300 m spool.

Use for

Use for feeders, branch circuits, control wiring, and panel terminations where a 600 V copper conductor with 90 deg C insulation is specified. The stranded 19-wire construction is commonly chosen where easier pulling and termination flexibility are preferred over solid conductor.

Avoid for

Avoid using this wire as nonmetallic sheathed cable or for direct burial. This is a single insulated conductor intended for installation in approved raceways or other wiring methods permitted by code.

Best for

Best for electricians needing a #10 AWG white conductor for identification in conduit runs, distribution equipment, or control cabinets. A 300 m spool suits larger projects, repeated pulls, or shop stock for ongoing service work.

Installed in

Typically installed in EMT, rigid conduit, cable tray systems where permitted, and electrical equipment enclosures. Approximate cable diameter is 4.2 mm (0.17 in), which helps when planning conduit fill, but actual fill must be verified to code and by conductor count.

Why this product exists

T90/TWN75 wire provides a common Canadian building-wire option for conduit systems where colour identification, pullability, and temperature rating matter. The nylon jacket helps reduce pulling friction, and stranded copper improves handling on bends and in tighter equipment spaces.

Compared with similar products

Compared with solid building wire, this stranded version is typically easier to pull and dress in panels. Compared with NMD90 cable, this product is a single conductor rather than a jacketed multi-conductor cable, so it is selected for conduit-based installations instead of exposed residential cable runs.

Typical trade guidance: #10 AWG copper is commonly associated with 30 A circuits, but final ampacity depends on insulation rating, termination temperature, ambient conditions, number of current-carrying conductors, and local code. Actual performance depends on installation conditions, layout, and Canadian Electrical Code requirements.
