LED'S keep tripping the RCD when switched off?

Just looked and it recommends 5 - FFS! And yes I ballsed up - was meant to write MCB in the title

Looks like you'll need to split the circuit then.

if the op has replace the 10 for led why would he put and a splitting them to a different circuit . he must have a fault on one of the lap C88p gear .

LED Batten Fitting 60W 1500mm 7200lm - https://www.toolstation.com/led-batten-fitting/p66469?searchstr=led%20batten I use these.

What is the total load on the respective mcb?
Possibly might need to change it for a c type

See his response In post #10, manufacturers recommend five fittings per circuit.

Are you using dimmers?
How many lights switch on/off simultaneously?

I suspect that the new LED lighting has a high crest factor, where Crest factor is the peak amplitude of the waveform divided by the RMS value of the waveform. So when a number of new LED fittings are supplied by the original mcb the electromagnetic functionality of the mcb detects the high total peak current and trips the breaker. The rms value is low and therefore there is insufficient Ohmic heating to cause the thermal functionality of the mcb to operate.

This is why there is a limit on the number of LED fittings per mcb size - you mentioned 5. I suggest you modify the wiring to power the lighting from 2mcbs, 5 LED strips on each. Or a higher current mcb if the wiring allows to power all 10 but this is not to be preferred.

Have you checked out the LED drivers,
by substitution ?
maybe a leak some where
