Single copper conductor with low temperature moisture resisting cross-linked polyethylene insulation.
CSA Spec C22.2 No. 38-95

Applications:

Colours: Standard colours are available.

Non-jacketed RW-90 (XLPE) cables are not suitable for installation in vaults and switch rooms under the conditions of C.E. Code Part 1 Rule 12-2204. Suitable flame retardant jacketed cables are available on request.

*For 3-wire 120/240 and 120/208V residential services or sub-services, the allowable ampacity for sizes #6, #2 and #4/0 AWG aluminum shall be 60, 100 and 200 amperes respectively. #2/0 AWG copper shall be 200 amperes. In these cases, the 5% adjustment per C.E. Code Rule 8-106(1) cannot be applied.

# Based on not more than 3 copper or aluminum conductors in raceway or cable. For 1 conductor per underground duct installation ampacities see below.

Applications:

For open wiring and raceways (except cabletroughs and ventilated flexible cableway) in dry or wet locations.
For exposed wiring where exposed to weather with sunlight resistant insulation. Standard Black #6 and larger is sunlight resistant and marked "Outdoor"; coloured insulation is NOT.
Minimum recommended installation temperature minus 40°C (with suitable handling procedures).
Maximum conductor temperature 90°C.
Approved for use with ceiling fixtures.

Parallel Cable Configurations

Recommended Configurations
For installation of single conductor cables IN FREE AIR

ATTENTION
Only these configurations are recommended by to obtain satisfactory load sharing.
Spacing between cables is one cable diameter (2 diameters centre to centre) for Can Elect Code Table 1 or 3 ratings. For 1/C cables direct buried, embedded in concrete or plaster and for 1/C cables in underground or embedded duct see tables bellow.

The installation of more than four conductors in parallel per phase without engineering analysis is not recommended. Neutral conductors to be located outside of the above groups in the most convenient manner. Spacing between groups to be equal to width of group.

Ampacity Rating and Recommended Configurations
For installation of single conductor cables IN DIRECT BURIAL

ATTENTION
Only these configurations are recommended by to obtain satisfactory load sharing and ampacity. See C.E.C. Code Rules 4-004, 12-012, Appendix B, Appendix D8 and Appendix D10.

Single Conductor Ampacities, Directly Buried Cables Types RWU90, RA90, TECK 90, ACWU90, 0 to 5 kV

Notes
The above ampacities are based on the following conditions:
– 100% load factor
– Ambient soil temperature of 20°C
– Soil resistivity of 90 C
–cm/W – Conductor temperature of 90°C
– Spacing between conductor centres of 7.5" and 24" between groups
– Burial depth of 36" to centre of top cable layer
– Open circuit sheath/shield operation

Neutral conductors to be located outside of the above groups in the most convenient manner.

Ampacity Rating and Recommended Configurations
For installation of single conductor cables IN UNDERGROUND DUCTS

ATTENTION
Only these configurations are recommended by to obtain satisfactory load sharing and ampacity. See C.E.C. Code Rules 4-004, 12-012, Appendix B, Appendix D9 and Appendix D11.

Single Conductor Ampacities in Underground Ducts Types RW90, RWU90 cable rated 0 to 5 kV

Notes
The above ampacities are based on the following conditions:
– 100% load factor
– Ambient soil temperature of 20°C
– Concrete thermal resistivity of 85 C–cm/W
– Conductor temperature of 90°C
– Spacing between duct centres of 7.5" (i.e. one cable per duct)
– Top of ductbank at 30" below surface
– 5" duct

Neutral conductors to be located outside of the above groups in the most convenient manner.
