Grounding doesn't stop at the electrical panel. This wire is an excellent choice for bonding solar module frames, rails, racking systems, equipment enclosures, inverter chassis, battery cabinets and other exposed metal components. Proper grounding helps equalize electrical potential, provides a path for fault current, and helps reduce the effects of static buildup and nearby lightning events.
Built for Safe, Reliable Electrical Installations
Grounding and bonding conductors play a critical role in electrical safety. This stranded #6 AWG copper wire provides a dependable path for fault current while helping ensure exposed metal equipment remains at the same electrical potential throughout the installation.
The stranded annealed copper conductor offers excellent flexibility when routing through conduit, electrical enclosures, or equipment compared to solid copper wire. Its durable PVC insulation and protective nylon jacket resist abrasion during installation while providing long service life.
Ideal for residential, commercial and industrial applications, this wire is commonly used for electrical panels, service equipment, transfer switches, generators, battery systems, inverters, equipment enclosures, disconnects, solar racking systems and other grounding or bonding applications.

Frequently Asked Questions
Why do I need grounding wire?
Grounding is one of the most important safety features in any electrical system. It provides a low-resistance path for fault current, allowing breakers or fuses to operate correctly while helping reduce the risk of electric shock.
Grounding wire is also used to bond exposed metal components together—including electrical panels, enclosures, conduit, generators, inverter chassis, battery cabinets and other equipment—keeping everything at the same electrical potential if a fault occurs.
For solar installations, grounding is equally important. Solar module frames, rails and mounting hardware should all be securely bonded together and connected to the grounding system to help dissipate static electricity and provide a path for transient voltages caused by nearby lightning.
Is this pure copper wire?
Yes. This wire uses a stranded annealed copper conductor, providing excellent electrical conductivity along with improved flexibility compared to solid copper wire.
Why does it have a nylon jacket?
The PVC insulation provides the electrical insulation while the nylon outer jacket adds abrasion resistance when pulling wire through conduit. It also improves durability and helps protect the insulation from moisture and everyday wear.
Can I use this wire for solar grounding?
Absolutely. This wire is an excellent choice for bonding solar panel frames, racking systems, equipment enclosures and other grounding conductors where #6 AWG copper wire is appropriate for your installation. Always follow the Canadian Electrical Code and the equipment manufacturer's installation requirements.
Does this wire need to be installed in conduit?
Not necessarily. While T90 building wire is commonly installed inside conduit or raceways, the Canadian Electrical Code permits #6 AWG copper equipment bonding conductors and larger to be installed without mechanical protection in many applications. Because grounding and bonding conductors are not current-carrying during normal operation, conductors of this size are considered robust enough to withstand the normal risks of accidental mechanical damage.
If the conductor will be installed where it could be exposed to known mechanical hazards—such as vehicles, machinery, sharp edges, landscaping equipment, or other high-risk locations—it should be protected using conduit or another approved method.
Always follow the Canadian Electrical Code and the requirements of your local electrical inspection authority.
Is this wire CSA and UL compliant?
Yes. This wire is manufactured to CSA C22.2 No. 75, UL 83 and CSA FT1 standards for copper building wire, making it suitable for a wide variety of grounding and bonding applications.
