Electricity: where is 208 volts used?

Self-tutoring about wiring: the tutor inquires about where 208V supply might be found.

Looking at the baseboard heaters the other day, I noticed they have two wattage ratings: one if in a 208V system, and one if in 240V.

I assumed this house is 240V, and even confirmed so at the source panel. Yet, I reflected, 208V must exist, and even be fairly common, if the baseboard heaters mention it.

Apparently, 208V is common in commercial buildings in North America.
