RWU90 copper building wire · 10 AWG 1 conductor 7-strand 1000V black · Southwire 10RWU90R

What this product is for

This is a single-conductor 10 AWG RWU90 copper building wire with 7-strand construction, XLPE insulation, and a 1000V rating. It is used for power distribution, service entrance, and branch circuit wiring in wet or dry locations where RWU90 conductors are specified.

Use for

• Conduit and raceway installations
• Industrial electrical distribution
• Service entrance and feeder conductors
• Wet or dry location wiring

Avoid for

• Applications requiring a multi-conductor jacketed cable
• Direct substitution where another insulation type or cable assembly is specifically required
• Installations that exceed conductor ampacity, temperature, or code requirements

Best for

Best for electricians and contractors needing a 10 AWG single conductor with more flexibility than solid wire, suitable for industrial and commercial raceway work. The 7-strand construction can make pulling and terminating easier than solid conductors in many field installations.

Installed in

Typically installed in conduit, raceways, and cable tray systems where permitted by code. Typical outside diameter for 10 AWG 7-strand RWU90 is about 0.24 in (6.0 mm), which can help when planning conduit fill. Actual installation requirements depend on local electrical code and site conditions.

Why this product exists

RWU90 wire is used where a 90 deg C wet or dry rated, 1000V insulated single conductor is needed for dependable power distribution. XLPE insulation supports use in demanding environments, including many industrial and outdoor wiring applications when installed as permitted.

Compared with similar products

Compared with solid 10 AWG conductors, this 7-strand version is typically easier to handle in pulls and terminations. Compared with jacketed cable, this product is intended as an individual insulated conductor for raceway-based wiring methods. As a rule of thumb, 10 AWG copper is commonly associated with 30A circuits, but actual allowable ampacity and overcurrent protection must follow the Canadian Electrical Code, terminal ratings, and installation conditions.

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