Spot the mistake ++++

[Doomed]

good neat job

 

[Gareth Brookes]

No I'd tags on switch lines

 

[littlespark]

Oh, I see it! They put the pattress box in upside down.
Pattress fixed with only one screw.
No sleeving on the blacks. (intermediate switch?)

 

[Gareth Brookes]

Or the orientation of the intermediate switch is left and right not top bottom
So the red and black should be one in top and one in bottom on the left and 1 top 1 bottom on the right

 

[Octopus]

Pattress fixed with only one screw.

Cripes, don't show that to your NICEIC assessor - he would have a field day - only 1 fixing screw!

 

[westward10]

No idea what this is about.

 

[littlespark]

maybe OP will wait a full hour before giving us the answer

 

[Doomed]

What sort of switch is it?

 

[Taylortwocities]

It is an intermediate light switch.
2-way circuit using twin&earth.
My guess is that the cpcs have been used as the strappers

 

[Richard Burns]

Perhaps it is an intermediate switch that has been wired as if it were a double pole switch.

 

[Adam W]

The 'neatness' extends no further than the confines of the pattress, and even then there is room for improvement in the way the sheath has been stripped.

 

[Wilko]

I also vote for misuse of cpc

 

[telectrix]

I also vote for misuse of cpc

only if it has been wired where a 3 core strapper would normally be used

 

[HappyHippyDad]

First choice is that the CPC's have been used as the strappers as it is an intermediate switch.

Second choice is that the black conductors are actually neutrals and this should just be a one way switch.

 

[Octopus]

What sort of switch is it?

As its YOUR thread , can't you tell us?

 

[The Ghost]

intermediate switch that has been wired as if it were a double pole switch

or vice versa

 

[Taylortwocities]

Perhaps it is an intermediate switch that has been wired as if it were a double pole switch.

Nah.
You’ll not break the circuit using an INT switch.
It either is straight through or reversal of L1&L2.

I think that's why Richard said it. We're looking for something that has been done incorrectly.

We have a winner

All the 2 way switching in the property dome in 2 core and earth, earth used as strappers and neatly sleeved in green and yellow.....

 

[Midwest]

I suppose being sleeved was a bonus.

So what are you going to do next?

 

[Toneyz]

If the CPC has been sleaved as that I think it's more than a mistake.

 

[Doomed]

So what are you going to do next?

All existing wiring is surface clipped, so I had been asked to chase out and flush it in. The client has now accepted my recommendation to change the two way switching wiring and also re route (with new) wiring in loft so he board it.
Effectivaly a partial re-wire now.

 

[Gareth Brookes]

Wow what an idiot I should have spotted but I guess that is where I still have a lot to learn

Your customer sounds a decent person ............ they have listened to your input and acted on it.

Nice one!

 

[littlespark]

How were we meant to see that with the clues given?

Two twin and earths at an intermediate switch is not uncommon if it’s a central joint box install.

ikr feed at both 2way switches, switch wire at 1 switch, then a t+e between for strappers picking up intermediates

the feed at 1 end is obviously not used and terminated into a connector

I could of taken a picture of the green and yellow sleeved earth in the common of the 2 way switch, but that would of been too easy

Was this done by an electrician?
