Cable run for Fixing a double socket on Chimney Breast

[Spike1947]

Hi

Would this be allowed : Fitting a double socket to a chimney breast , chased a horizontal run across the chimney breast then to the first corner then along horizontal to about 500mm to meet up with a double socket feed that comes down to a double socket and then it follows that run down into that back box to pick up the feed .

The cable is in a oval plastic conduit and will be just below the surface , the house has RCD protection .

i would come horizontally from existing socket onto chimney brest, then vertically to your new socket. makes the safe zones easier to follow. or....... up from existing socket int ceiling void, then across to chimney and verticall down to new socket.

Technically the 500mm you chased horizontally to meet the vertical chase would not be in the zones.
I have drilled diagonally through the chimney breast wall before to make the horizontal chase on the face of the chimney meet the vertical chase on the side. The walls are more than thick enough to avoid going into the chimney cavity quite easily.

Thanks for the feedback, just a note , the chimney breast is flush with the wall ! .

then either way is compliant.each socket will create a safe zone for the cables.

 

[Spike1947]

Maybe this will explain it better !

 

[Andy78]

The 500mm bit on the non chimney wall is not in zones then. Well, 350mm of it isn't.

 

[Spike1947]

Is that a no go them !

NOT permissable

 

[Andy78]

You could go sideways from the low socket, then up in the 150mm zone formed by the corner, then across to the chimney socket.

To be blunt this should be in the DIY section................. so maybe employ a spark?

What instruments do you have to test the completed circuit?

If it is going to be a non complient circuit , then there is no need to go there .
Would you need to Meggar a 4 mtr length of new cable that goes from one double socket to another ! .

I’d do the vertical run in the corner of the two walls.

Cheers for that , Yes that is the solution as best to do in the situation

Once you're done 'meggering' the circuit, remember to 'hoover' up the dust.

Not sure if you are being sarcastic there !

Try not to be blunt !

Be careful not to puncture the chimney in any way. Ifs it's not an active chimney now then it may well become active in the future and could leak harmful gases.

Hi
Yes thanks for that , had taken that onboard .
cheers

Non compliant with what? There is always a need for testing how else do you know it’s going to be a safe installation? and you should carry out more tests than just IR. continuity of bonding conductors CPCs, Polarity, PFC, Ze, Zs, RCD trip times excuse me for being an a**e I didn’t realise you were qualified till I looked at your profile just there...

Hi
I don't need to mention doing basic tests like , Polarity /continuity etc , it goes without saying that you would do those checks ! , it is just a very simple wiring job , I can nearly touch each end of the cable with both hands ! .

Sorry as I said I didn’t realise you were a spark until I checked your profile. Lots of people come on here wanting advice on things like this and don’t have a clue or any test gear.
Have you not got anOSG? The safe zones are pretty well explained in there.

Is this an old house? Chimneys tend to be sticking out from the wall, so you might find the area of wall to the left and right of the chimney actually plasterboarded over alcoves.
Is the socket for a wall mounted TV? Do you need to also find a cable route for the AV cables?

Even though it's a short run it will still need to be tested properly. As you should know, even a small section damaged can deem it unsafe

Hi
Yes it is a old house and yes it is for a wall mounted TV , the whole wall is solid brick , AV cables n Sky etc coming in from opposite wall .

I'm lost.
AV coming from opposite wall? In the same room, or the room behind the chimney?. Can the power come the same route?
Are you drilling right through the wall? Beware of the path of the chimney, it might start off central to the fireplace but veer to one side just above. I (recently did the same job, tried to drill into chimney for TV cable route and missed)

Getting your opposite and adjacent mixed up there? Trigonometry not you strong point?

Well I am a little older than you I guess , not really worked in the trade for roughly 20 years or so , so a little relapse now and again in spelling etc is inevitable .
Actually I was quite good at Trig n Tech drawing in my younger days

Just imagine the confusion if he'd mentioned the hypotenuse as well!

right on. sine or cosine, who cares?
