FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

When should I choose ACWU90 versus TECK90?
Choose ACWU90 (CSA C22.2 No. 51) for commercial buildings, underground utility distribution, data centres, solar farms and non-hazardous industrial plants where you want direct-burial and wet-location protection in a lighter, smaller-OD, lower-cost armoured cable. Choose TECK90 (CSA C22.2 No. 131) for heavy mining, pulp/paper, chemical refineries or classified hazardous locations requiring the extra inner PVC bedding jacket.
How does ACWU90 differ from AC90?
AC90 has an exposed bare interlocking aluminum armour and is restricted to dry indoor locations only. ACWU90 adds a moisture-, sunlight- and -40 °C flame-retardant FT4 PVC outer jacket over the aluminum armour, qualifying it for wet locations ('W') and direct earth burial ('U').
Is ACWU90 available with aluminum conductors as well as copper?
Yes. While TECK90 is traditionally manufactured with copper conductors, ACWU90 is widely specified in both annealed copper and compact AA-8000 (ACM) aluminum alloy conductors for large 1/0 AWG to 750 MCM feeders.
Does ACWU90 require conduit when buried underground?
No. The 'U' in ACWU90 certifies direct earth burial under the Canadian Electrical Code without raceway, though sand bedding or mechanical protection is used under vehicular roadways.
