10 RW90 Copper · 600 V XLPE Insulation · White Solid

What this product is for

This RW90 single-conductor copper building wire is used for branch circuits, service wiring, and general raceway installations in Canadian residential, commercial, and industrial work. It is a 10 AWG solid conductor with white XLPE insulation and a 600 V rating.

Use for

Use for conduit and approved raceway wiring in dry or wet locations, and for open wiring where permitted by code. White insulation helps with conductor identification in panel, junction, and branch circuit work.

Avoid for

Do not use as non-jacketed exposed cable where the installation method is not permitted by the Canadian Electrical Code. Non-jacketed RW90 is not suitable for vaults and switchrooms under certain code conditions, and coloured conductors in this size are not typically marked sunlight resistant unless specifically identified by the manufacturer.

Best for

Best for electricians and contractors needing a 10 AWG copper conductor for raceway-based power wiring where a 90 deg C insulated conductor is required. Typical trade guidance: 10 AWG copper is commonly used on 30 A circuits, but final conductor and overcurrent selection must follow equipment ratings and local code.

Installed in

Typically installed in conduit, tubing, or other recognized raceways in homes, commercial buildings, and industrial facilities. Minimum recommended installation temperature is approximately -40 deg C (-40 deg F) with suitable handling procedures.

Why this product exists

RW90 gives contractors a thermoset insulated copper conductor for 600 V systems where moisture resistance, 90 deg C temperature rating, and code-recognized building wire performance are needed. The white insulation supports phase or neutral identification depending on the wiring method and code application.

Compared with similar products

Compared with stranded RW90, this solid 10 AWG conductor is typically chosen for straight pulls and smaller branch circuit work where flexibility is less critical. Compared with jacketed cable assemblies, single RW90 conductors are selected when the installation is being run in conduit or another approved raceway system.
