347VAC Sensors: Is There A Mounting Difference Between The 347VAC Wall Switches Sensors?

The Canadian standard for 347 VAC wall switches such as the WSD, WSX and LWS utilize a slightly larger switch box.  As a result, a standard 120/277 VAC wall switch will not mount into a 347 VAC switch box.   The length of the mounting ears are about 1/8" longer on the 347 VAC switch than on the standard unit.

The attached image shows the difference.
