Hi
I am a technician working mainly with lighting, sound and av equipment for the entertainments industry.

I have recently come across a unit which I am struggling to design a testing scheme for and am looking for any input I can gain.
The unit is a rack mounted touring dimmer unit, with 6 6 channel rack mount dimmers, a patch panel and a socapex output panel. Additional the unit provides multiple non dim outputs. The power input is a 3 phase 125a ceeform connector.

My concern is while performing an earth leakage test, the unit currently fails as a whole on the 0.75ma limit, however it passes the 3.5ma limit of a static appliance. Each individual dimming unit will also pass the 0.75ma limit. The unit is currently not in use as a fail, however I am unsure if testing it as a class 1 on portable appliance is fair as the unit is over the 18kg suggested weight for transportable appliances (by some pat tester providers) and forgetting its flight case mount is as easy to move as a fridge. however it is a touring unit and designed to move on a regular basis.

Despite it being so heavy and so big, should I test the unit as a portable appliance, or is it fair to treat it as a static appliance?

can I perform the earth leakage on each individual unit within the main unit, or should I treat it as one whole thing?

Thankyou in advance for any help you may be able to give!
