Use of switching of a circuit breaker on-load (light or heavy) would hinge on if you think a monthly operation counts as 'infrequent', and if this is in accordance with the manufacturers instructions as to the duty cycle of the device - which is what I was getting at.
The emergency light testing can be combined with the 6 monthly R.C.D testing. I have never known a M.C.B. wear out due to regular switching off and on again. I know a church hall that uses only its Crabtree brown M.C.B.s as functional switches to switch its fluorescent lights on and off as there are no light switches. They have done this two or three times a week for over 50 years and the original M.C.B.s still function well.
