AC90 · 10/3 · Cut To Length Armoured Cable · 10/3BX-Cut

What this product is for

This product is a 10 AWG 3 conductor armoured building cable, commonly referred to in the trade as 10/3 BX and typically listed in Canada as AC90. It is used for 600V branch circuit and feeder wiring in dry locations where the cable needs mechanical protection without installing separate conduit.

Use for

Use for dry-location wiring runs in residential, commercial, and light industrial work, including equipment feeds, larger branch circuits, and installations where armoured cable is preferred. Typical conductor makeup is 3 insulated copper conductors plus a bonding wire inside interlocked aluminium armour.

Avoid for

Avoid using this as a substitute for cable types intended for wet locations, direct burial, or exposed corrosive environments unless the exact manufacturer listing specifically allows it. Do not assume all 10/3 armoured cable has the same conductor stranding, jacket construction, or approvals.

Best for

Best for electricians and contractors who need a protected 10 AWG multi-conductor cable for indoor dry-location work in commercial suites, service rooms, workshops, and renovation projects.

Installed in

Commonly installed in walls, ceilings, service spaces, and exposed interior runs where AC90/BX is permitted by code. Typical outside diameter found on comparable 10/3 AC90 listings is about 0.57 in (14.5 mm), but this varies by manufacturer.

Why this product exists

AC90/BX cable combines insulated copper conductors with interlocked aluminium armour so installers get cable protection and a practical wiring method in one assembly. This can reduce labour compared with pulling individual conductors in conduit for some indoor applications.

Compared with similar products

Compared with NMD90, AC90/BX provides added mechanical protection for exposed or more demanding indoor runs. Compared with Teck cable, AC90/BX is typically chosen for dry interior building wiring rather than wet-location or direct burial work. As a rule of thumb, 10 AWG copper is commonly associated with 30A circuits, but final conductor and overcurrent selection must follow the equipment rating and Canadian Electrical Code.

Actual performance depends on installation conditions, termination temperature ratings, bundling, ambient temperature, and local electrical code.
