VFD supplied by RCBO vs MCB?

[mattnedgus]

Is it wise to run the CNC including VFD etc from behind an RCBO or is an MCB better?

I read in the VFD manual something about it not wanting any potential disruption to power and got the impression this included any kind of RCD...

At the moment the 2.2kW VFD, 4 x NEMA23 stepper motors, PC and monitor (and 1kW CamVac) are all coming off the 32A ringmain that supplies the downstairs sockets but I am planning on installing another circuit breaker dedicated to the CNC equipment to reduce the risk of tripping. (I switch on two linear power supplies and VFD one at a time (with a switched extension lead) to avoid tripping the MCB with the inrush current but I'm looking at buying a new dust extractor that requires a 16A feed!)
