10/2 NMD90 Red · Non-Metallic Sheathed Residential Building Wire · 150M Reel

What this product is for

This 10/2 AWG NMD90 copper building wire is used for indoor branch circuit wiring in residential and light commercial construction in Canada. It is a non-metallic sheathed cable with two insulated conductors and a bare bonding wire, supplied on a 150 m reel.

Use for

Use for exposed work in dry locations or concealed work in dry or damp locations where NMD90 is permitted by code. The red jacket version is commonly selected for 208-240 V circuits with red and black phase conductors and no neutral, including typical electric heating circuit runs.

Avoid for

Do not use in wet locations, underground runs, or where a neutral conductor is required. Do not use where cable type, ampacity, or installation method does not meet the Canadian Electrical Code or local inspection requirements.

Best for

Best for electricians and contractors wiring indoor 300 V circuits that need #10 AWG copper conductors on a full 150 m reel. This format suits longer pulls, repeated rough-in work, and projects where red and black conductor identification helps separate 208-240 V circuit applications from standard black and white branch wiring.

Installed in

Typically installed in houses, apartments, renovations, and light commercial interiors. Common installation areas include wall cavities, floor systems, and other protected indoor spaces in dry or damp conditions.

Why this product exists

This cable provides a CSA-compliant NMD90 option for Canadian indoor wiring where two insulated #10 AWG copper conductors and a bonding wire are needed. The 150 m reel reduces splice planning and is practical for larger rough-in jobs.

Typical trade guidance: #10 AWG copper is commonly associated with 30 A circuits, but actual allowable use depends on equipment ratings, termination temperature limits, installation method, and local electrical code.

Compared with similar products

Compared with 12/2 NMD90, this 10/2 cable is chosen when a larger conductor size is required. Compared with standard black and white 10/2 NMD90, this red jacket version is intended for applications using red and black insulated conductors. Compared with armoured cable, NMD90 is typically selected for protected indoor spaces where a non-metallic sheath is acceptable.
