CISPR 22 includes Class A emission limits, which are appropriate for the industrial environment. Conducted emissions propagate through the power distribution system, whether the equipment is fed from the low-voltage public supply or otherwise. The limits on conducted emissions are at least partly intended to limit the consequent radiation from the power supply conductors. So it's difficult to justify different conducted emission limits simply on the grounds that the low-voltage supply is not shared with other customers of the supply company. -- OOO - Own Opinions Only.
