Lighting contactor wiring

[buzzlightyear]

I have already changed to a c6

what size of cable is being used on lighting.

 

[telectrix]

try a C10 if the Zs is low enough.

Agree @westward10 - I don't see how a contactor helps, unless its switching 2 circuits.

 

[Ghost2011]

The cable size is 1mm t+e

No nor me

I’m am at the property now and have put a c10 mcb in and all seems good have tried them over 50 times and no tripping

You may find your switch gets damaged over time though. As has been said a current limiter prior to the switch is the more conventional method of dealing with inrush currents. Contactors, relays and switches are all in line of the inrush and will suffer over time. I hope with the C curve MCB you have taken account of the ADS and max Zs that it meets required disconnection times? There is much evidence of fusing and meltdown of contactor, relays and switches in such circuits.

Does the Zs come within the parameters of a C10 CB?

try a C10 if the Zs is low enough.

Also depends upon the installation method existing.
