RCD before CU

[scousespark]

That's fair comment regards the cable size, but I'd say 8 out of 10 of my mates would install 1.5.

 

[riveralt]

the earth wires were removed from the metal light plates. I re-instated them

Presumably you did that rather than replace the accessories with plastic ones.

Did you measure R1+R2 at each switch?

No reply you worship!

If you were looping through the switch boxes you would use 1.00mm

No I wouldn't. I'd use a wago to connect the 1.5 neutrals. Also, from reading your posts, you appear to have butchered a circuit because you didn't understand it. Have I missed something here? Was there a problem with the original switch?

Also, the table you referred to should only be used as a guide. I would suggest you read up on cable calcs.

I fully understand it OK! There were too many cables in the box, with too many 1.5mm wires and terminal blocks.

I have used a wago. I looked them up and can't see where they would help.

I did ask if there was a problem with the switch.

wagos are tiny and you push fit the conductors.

Did you test for insulation resistance, cpc continuity, polarity and fault loop impedance?

What testing did you do, particularly of cpc continuity?

Did you measure R1+R2 at each switch?

Colin - do you have a reason for never answering my question about testing?

Meh, lever is nicer.

agreed, but when space is tight, the push fit comes in useful.
either is better than a connector block.

Knackered dimmer.

Thanks. I'l look at them. I knew they were pushfit.

Can the wires be pulled back out?

Ericmark and others had no problem understanding it.

Yes, you twist them to remove. Or use the lever type, which just require a fingernail sacrifice.

The convention is via the ceiling roses

Au contraire, increasingly, the convention is via switch boxes.

I see no purpose made boxes on the market for this - unlike ceiling roses.
