I have installed some generation 2 LightwaveRF units.
I have replaced a 3 gang switch downstairs with a new Gen 2 3 gang switch (just released) - one of the gangs is a 2 way landing light.
I've also replaced the upstairs landing switch with a Gen 2 1 gang switch.
Note that Gen 2 units aren't master and slave like Gen 1 units - that's done in software.
The original wiring can be seen in the photos.
Upstairs:
Switched live (black) and 3 core blue to L1
3 core yellow to COM
Live (red) and 3 core red to L2
(Note this seems somewhat different from most standard wiring diagrams)
Downstairs: (the left most gang)
3 core red to L1
3 core yellow to COM
3 core blue to L2
Following the lightwave instructions here (https://support.lightwaverf.com/hc/...tion_2__2_way_with_one_intermediate_point.pdf) I have done the following:
Upstairs: (now 1 gang gen 2 lightwave rf unit)
Live (red) to 'L'
Switched live (back) AND 3 core yellow to 'X/switched'
3 core red and blue capped
Downstairs:
3 core yellow to 'X/switched'
3 core red and blue capped
NB - the whole 3 gang unit only takes ONE live input - this powers all 3 gangs. This is from one of the downstairs lights (the other two gangs are 1 way porch and hall).
(See https://support.lightwaverf.com/hc/en-us/articles/115001530231-Lighting-guides-Generation-2- for the manuals)
Result:
The upstairs light switch works fine
The downstairs light switch trips the RCD
WHY??
Is it because the power is effectively coming from the downstairs circuit yet the switched live feeds an upstairs light - does this create a imbalance the RCD senses??
If so what can I do about it - as, unlike the 2 gang gen 2 unit which has one live input for each gang, the 3 gang only has one - and if I was to use one of the other 3 core wires to take a live from upstairs presumably then the two downstairs switches would trip.
Grateful for thoughts.
Thanks
