10 T90/TWN75 · Copper White Stranded Cut to Length

What this product is for

This 10 AWG stranded copper T90 nylon building wire is used as a single conductor in conduit and raceway systems for commercial, industrial, and some residential electrical work. It is intended for 600 V circuits where a flexible stranded conductor is preferred over solid wire for pulling and handling.

Use for

Use for services, feeders, and branch circuits in conduit or raceways. It is commonly selected where white insulation is required for identification and where 10 AWG copper is needed for equipment connections, control runs, or branch circuit conductors.

Avoid for

Avoid using this wire as a finished cable assembly without conduit or an approved raceway system. Typical T90 nylon building wire is not intended for direct burial, and standard T90 applications are not for sunlight-exposed runs unless the specific listing says otherwise.

Best for

Best for electricians and contractors needing a stranded 10 AWG copper conductor that pulls more easily than solid wire in conduit. It is a practical choice for commercial and industrial raceway work and for installations where conductor flexibility helps at terminations and bends.

Installed in

Installed in conduit and raceways in dry or damp locations, including exposed or concealed wiring applications permitted by code. Typical trade guidance: 10 AWG copper is commonly used on 30 A circuits, but final conductor sizing must follow the Canadian Electrical Code, equipment terminations, derating, and installation conditions.

Why this product exists

This product provides a single insulated conductor for raceway wiring where installers need colour identification, 600 V insulation, and the easier handling of stranded copper. The nylon jacket over PVC insulation helps reduce pulling friction and supports common building wire applications.

Compared with similar products

Compared with solid 10 AWG building wire, this stranded version is easier to pull and route in conduit, especially on longer runs or tighter bends. Compared with cable assemblies such as NMD90, this single conductor is intended for conduit and raceway systems rather than open cable runs. Actual performance depends on installation conditions, layout, and local electrical code.
