Wrong wiring for lighting circuit

[freepo]

I was just watching property ladder, and the guy said that after they had just installed the lighting circuit, they had found out it was the wrong sort of cable.

Can you think of what he meant? They didn't actually say any more on the subject - which is really annoying for a viewer, if we are not to make the same mistakes they should bloody well say what the exact problem was.

The only things I can think of are low voltage lights, and the wrong colour coding of cables, which changed a few years ago. Can you think of anything else it might have been? Thanks

Given some of the numptiness on there, maybe using three-core flex? Bell wire?

Might be they used 2.5mm^2 T&E... hard to use an undersized one unless it was a 10A circuit with cables under insulation etc.

T&E instead of 3-core+E?

Can you still buy that?

Screwfix list both on

realised just how many lights he was going to have in a converted barn lounge. Ripped out 1mm^2 and replace with 1.5mm^2. Could be that.

Sorry - I read it as twin rather than TW&E. Looking for something that made sense.

Possibly that an earth-shielded cable to BS 8436, such as Earthshield or Flexishield, was needed to allow it to be buried in the walls without RCD protection whilst complying with the 17th edition?

I can see why perhaps, as I'm not finding it there^

Perhaps it was a bit of washing line.

Brown brown instead of brown blue?
