Re: Wire prices

["Doug" <not@xxxxxxxx>]

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.
