No isolation except  the supply circuit breaker for  external  A/C units, no manufacturers instructions . Is this always a C2  It is in my eyes but checking before i   complete a report, that anyone may have a reason its a C3

MCB can be used for isolation so no code

 

table 537.4

Agree with the above but this is a glaring issue now we have RCD's ................ how can you provide DP isolation using a MCB to "rule out" a fixed appliance being the cause of a RCD trip?

Isn’t there a requirement for local isolation within 2m of equipment for maintenance purpose? 

I know all our AC installs have an isolators adjacent to outdoor unit.

Never seen AC without a local isolator, think I would agree it's bad practice to rely on MCB as this does not isolate Nuetral. C2, not sure?
