im doin some wiring for a large building (and before you ask, yes i can do it, i have a specification and someone will be testing/issuing certs), but the spec says switch 1 should be fed thru contactor 1 and switch 2 should be fed thru contactor 2. both contactors will be switch from a fish keyswitch in another part of the building. i understand how to connect this, but the question is, what do i do for power for the switchin circuit?
do i take it from live and neutral coming into the contactor for each (bearing in mind that the switch is in a totally differnent location)
or
have a seperate MCB in the DB for the switching?
