Underground electrical cable · 10/3 NMWU Direct Burial 75m Reel

What this product is for

This 10/3 NMWU copper cable is used for underground power distribution where direct burial is permitted. It is intended for outdoor wiring in wet or dry locations, including runs to detached structures, yard equipment, and other buried branch circuits where the cable is not exposed to mechanical damage.

Use for

Use for direct burial underground installations, outdoor branch circuits, and feeder runs that require three 10 AWG copper conductors in a moisture-resistant jacket. A 75 m (246 ft) coil suits longer residential or light commercial runs without splicing from shorter lengths.

Avoid for

Avoid using this cable where it may be subject to physical damage without added protection, or where a different voltage rating, conductor count, or installation method is required. Confirm suitability before using in conduit systems, exposed locations, or applications with higher temperature requirements.

Best for

Best for electricians and contractors wiring underground outdoor circuits in Canadian conditions, especially when a direct burial cable is preferred over pulling individual conductors. It is commonly selected for detached garages, sheds, pumps, and similar outdoor loads.

Installed in

Installed in underground trenches for exterior residential and light commercial projects, in wet or dry locations where direct burial cable is acceptable under code. Typical installations include buried runs between buildings and outdoor equipment feeds.

Why this product exists

NMWU cable provides a practical way to install underground power without assembling separate conductors and raceway for every job. The factory jacketed cable helps simplify handling on site while meeting common Canadian direct burial wiring needs.

Compared with similar products

Compared with NMD90 indoor cable, NMWU is intended for underground and wet-location use. Compared with smaller gauges, 10 AWG is commonly chosen where circuit length, load, or breaker size requires a heavier conductor. As a rule of thumb, 10 AWG copper is typically associated with 30 A circuits, but final conductor sizing, derating, and overcurrent protection must follow the Canadian Electrical Code and site conditions.
