Answer Posted / mick
A circuit breaker is designed to automtically open the live
line if the current exceeds its rating - i.e. a 5A circuit
breaker will open and disconnect the live line should the
current exceed 5A. It primary purpose is to automtically
disconnect the live under a fault.
A isolator is usaully a hand operated device that will
disconnect the live and the neutral. Manly used to allow
work to be carried out on equipment (a motor for example).
Normally an isolator will have some way of being 'locked
off' so that the equipment cannot be energised. It does not
have an automatic function.
