Isolation requested

Former Community Member
Former Community Member
Good morning All, 


I need to understand something. 

I know the regulation request the isolation as requested for each electrical installations. 

In the scenario where I have the distribution board close to all the electrical equipment (same room)

and each line is separated and protected by their own MCB.

Do I need to install the isolator too? 

I can isolate every circuit directly from the DB?

Thank you and have a nice day

    I don't think that there's a specific requirement to have a separate isolator from the MCB.


    But the manufacturer's instructions may require such an isolator.  There may also be a good safety reason to have a lockable isolator so that the equipment can be shut off for maintenance while everything else is left powered on.  That's really a judgement call based on where the equipment is, and the possibility of someone turning the equipment back on when they shouldn't do.
