Description
TECK90 • 8 AWG • 3 Conductor Copper • Sold Per Meter
8/3 TECK90 Armoured Copper Cable – 1000V Outdoor Feeder Wire for Sub-Panels, Equipment, HVAC, Pumps & Direct Burial Runs
8/3 TECK90 cable is a rugged armoured copper cable used for Canadian outdoor feeder and equipment wiring where mechanical protection, wet-location durability, and reliable jobsite performance matter.
Sold Per Meter – Order the Exact Length You Need
This 8/3 TECK90 cable is sold by the meter. Enter the total number of meters required in the quantity box. For example, quantity 10 means you are ordering 10 meters of cable, cut as one continuous length whenever possible.
Ordering tip: Add allowance for routing, bends, panel entry, disconnect entry, service loops, and terminations. For long runs, confirm voltage drop and final conductor sizing with a licensed electrician.
Built for Canadian Feeder, Equipment & Outdoor Wiring Jobs
8/3 TECK90 armoured copper cable is commonly used by electricians for feeder and equipment wiring where standard indoor cable is not suitable. Typical applications include detached garage feeds, workshop power, small sub-panels, pumps, compressors, HVAC equipment, rooftop mechanical equipment where load requirements permit, outdoor disconnects, agricultural power, light commercial equipment, and direct burial runs.
The interlocked armour helps protect the conductors from physical damage, while the black outer jacket supports demanding outdoor, wet-location, exposed, underground, and mechanical equipment environments when installed with approved TECK connectors and local code-compliant methods.
Recommended TECK Connector for 8/3 Cable
For most 8/3 TECK90 installations, the recommended connector is TMC2-07A118. Add connectors with your cable order to avoid a second trip, a second shipment, or jobsite delay.

FAQ
How do I order 8/3 TECK90 by the meter?
Enter the number of meters you need in the quantity box. Quantity 1 means 1 meter, quantity 10 means 10 meters, cut as one continuous length whenever possible.
Which TECK connector should I use for 8/3 TECK90?
TMC2-07A118 is the recommended connector for most 8/3 TECK90 installations. Always confirm the connector opening, cable diameter, enclosure, and installation conditions.
Can 8/3 TECK90 be direct buried?
TECK90 is commonly used for direct burial applications where approved. Burial depth, warning tape, mechanical protection, transition points, and inspection requirements must be confirmed before installation.
Can 8/3 TECK90 be used for rooftop HVAC equipment?
Yes, it may be suitable for smaller rooftop units and light commercial mechanical equipment feeds where the equipment load requirements permit. Larger RTUs may require larger cable, so sizing must be verified by an electrician or project engineer.
Can 8/3 TECK90 be used for EV chargers or hot tubs?
It may be suitable for certain lower-amperage EV charger, spa, or outdoor power applications depending on equipment rating, breaker size, conductor ampacity, voltage drop, and local code. Higher-output EV chargers and many hot tub installations may require larger conductors.
