Another electrical adventure

I wanted to swap round the two switches of a double light switch in myliving room. First I switched off the 'downstairs lights' RCBO only tofind (on checking) that the lounge is connected to 'kitchen lights'. Idon't think I'll trust these RCBOs again :-) I reversed the cables at the the top. As the two COM inputs werebridged with a (red) cable, I decided there was no need to changethese. I assume this is okay so far. All the cables are red, so isthere any need to add brown sleeving when it is obvious what a redwire means in a 'mixed wiring' situation? There is no gromet. Am Iallowed to cut a gromet to install this without disconnecting anycables or is this regarded as bad practice?

So you are just referring to the box there and not the switch?

Yup that is ok.

Too many late night postings by me! The switch is non conductive. The box is behind but the screws are attached to the box so I understood they required to be earthed.

At my last place if you touched a screw, you would get a mini shock. I assumed this was static from the carpet going to earth but maybe we should have checked the earth at the time.

Thanks. I have now found a worse one but I think my friend who is a (retired) electrical engineer could be persuaded by a curry to look at it!
