UK RCD nuisance tripping

How many 16A sockets are within each unit or is it one unit.

How many 16A sockets are within each unit or is it one unit.

1 per unit, the obvious answer would be to install more circuits and have them split the CPU’s up in to multiple circuits per unit.

Put an internal distribution board in.
Are these for your benefit these screens or are they renting space.

Are they permanent structures, or do you have to be able to move them around and unplug them, etc?

If fixed wiring and no risk of cable damage, etc, you could avoid the RCD but really would be looking at high-integrity earthing (two separate earths, no common fixing screws, etc) due to the huge leakage current.

They should have RCD protection if they can be touched by the public.

Are these LED displays lile commercial monitors or an LED matrix?

Does the LED array have its own power supply or is it in strings and powered by main voltage? Reason being if they are powered like that it will cause a halfwave DC component and could be why your getting tripping.

Which regulation would that be?

RCBO's are different to RCD's from your post you seem to think they are the same.

RCBO's are one of the many types of RCD

 

[Mike Johnson]

Are you saying they are the same?

Are you saying they are the same?

RCD is a group of devices. RCBOs are one particular type of RCD.

I think the OP is well aware of the differences.
