VFD supplied by RCBO vs MCB?

[mattnedgus]

Power being cut cleanly isn't an issue, what is an issue is brown outs/surges/spikes in the incoming power.
I certainly would still want a RCD of some form in the supply.

An issue you may face though is the RCD/RCBO tripping due to the way the filtering in VFDs work. For single phase installations you really want Type A.

Thank you for helping to clarify, I think what I'll consider doing is adding an A-type 40A RCBO and running a 16A socket for the cyclone extractor and two more UK-3-pin sockets - that way, I can try the VFD in the RCBO and if there's a problem, switch at least "it" back to the MCB!
