Chuck, those codes can be different from one jurisdiction to another, here in the US. Where I am in rural AZ, there's nothing except common sense to prevent wiring several machines to one circuit. The inspector who signed off on my shop wiring job never even asked. And, a couple stationary machine were in place when he did the inspection.
