Solutions for Surface mount to conduit.

I am being picky here cos it looks a good job, do you think the conductors into the new box are correctly contained.

Not quite sure what you mean. The new box had an RCD socket fitted. Wires either went into the socket or were joined with Wagos to complete the ring.

Like a said being picky but there is no containment for the conductors between the existing back box and the new box aside from butting them together.

I don't get it, there is a KO box in the wall and a surface pattress over the top as long as the KO box is earthed I don't see a problem. Why would it need containment between the two?

It is nothing to do with earthing but the containment of conductors between the two.

Why does it need containment out of interest? You wouldn't put containment between a flush box and thermostat/programmer back plate for example IMO its a similar scenario.

If a door from a room leads away from a hazard to a place or route of safety it is deemed an escape route and from the picture I suspect it does.

Using that definition, that would mean every room in any property in every premise is part of an escape route? I'm not sure about that.

The conductors stop at the accessory and are contained within the back box. In this instance although as I said being picky they pass between enclosures . Would you butt up two conduit terminal boxes through a thin partition without some forms of bush. I agree in this instance it is an air space but it is that space where containment is absent.

Give me an instance where a door may not be an escape route. If you have passed through it there may be a requirement for you to pass back through it an emergency situation, even the door to a toilet cubicle. You are sitting on the loo and the fire alarm goes off that cubicle door is your escape route, far fetched but true.

No absence of containment. The building structure is permitted to form part of the enclosure.

Hi - my 20p worth - aim is to create one containment, consisting of the original back box, the new pattress and the face plate. If successful no additional segregation or containment would be required. The new containment would need to be rigidly joined and pass IP-wise, which it looks like. Or have I misunderstood? (Prolly not enough unpickled brain cells left.)
