Virtually all single pole 15 and 20 amp breakers are Switching duty rating (SWD) (UL says no more than 20 amp for switching duty rating), so the argument about wearing them out is nil. However, breakers up to 50 amp that are marked HID are also switching duty rated for use with HID circuits and as such are not prone to failure with repeated use like non rated breakers would be.
