VRF Equipment fed off local Lighting Circuits

Eddie Currents
What are your thoughts with VRF Equipment being fed off local Lighting circuits – For me not good practice and strongly oppose this but i cannot find a Clause anywhere in the new Regulations. Has anyone ever come across this before or am i being too pedantic ? The VRF Units will have local isolation but for me its still a problem as you will lose your Lighting if you need to switch off at the Breaker for any reason like switching for Mechanical Maintenance.

    It would yes but just not keen on the idea of them being wired on local lighting circuits for the sake of another seperate circuit or 2. Maybe I'm over thinking this 




    What is the worst that could happen if a service engineer turns off a switched fused connection unit and removes the fuse to work on the equipment, after affixing a warning notice. You could always install new isolating switches high up adjacent to the units for isolation by maintenance engineers, perhaps even in the false ceiling if there is one.


    I'd send a strongly worded memo to "management" to cover my a**.


    How large are the areas in question? Is there emergency lighting or borrowed light (Indirect lighting from other areas say coming in through glass) in case of a lighting failure?
