You guys are missing the point. The device (switch/outlet) is already
grounded by the ground wire from the supply line. Unless, they use very
different wire in Canada...why would you want to connect a plastic box to
the ground??? The device is grounded, the box is plastic, the cover plate is
plastic...what exactly are you grounding ???
|I imagine the purpose isn't to "ground" the box, but to try to ensure the
| ground is passed through to the device being mounted on the box. The
ground
| lug appears to be tied to the device mounting screw sockets, any device
| mounted to the box will be grounded. It may also be to try to ensure the
| ground continuity to devices further down the circuit, who knows, but a
| quick google seems to confirm that it is a requirement of the Canadian
| Electrical Code.
|
| This is from a document on Carlon's website.
|
| Canadian Applications: Per Canadian electric code, a separate bonding
| connection is required in nonmetallic electrical boxes. Utilize Grounding
| Lug (Fig. 11) and green Ground Screw provided with Yoke.
