What code? bonding conductor

[Doomed]

Back of the board has been knocked out leaving internal conductors exposed to a combustible surface.

0
and the plastic CU is not combustible?
That is the standard rear knock out on the old crabtree CU

Check tightness of screws, if loose, tighten.

No code

I must say I see many CUs around here installed on wooden battens and all cables coming in through the rear knockout. Usually Wylex or Crabtree. Seems to have been the standard way of doing it for a long time.

Indeed. It's particularly advantageous where you need to add cables later. If access is tight, making a new hole in the side/top/bottom of a CU can be a right pain.

Bit confused where does mounting it on battens come into it. The board in the picture clearly has the back knocked out, is mounted flat leaving conductors exposed to a combustible surface.

Like the Plastic CU

You can’t code it for being mounted on a wooden surface even with the back cut out IMO without evidence of a problem or even loose connections.
Bit like a plastic consumer unit which is combustible.
Check tightness of connections,tight and secure, no code.

I was replying generally to the idea of using rear knockouts. In the OP's picture it does look like the CU is mounted straight on a wooden surface, with the back knocked out. Not sure why I must say.

You mean can't code it?

Ha yes!
I shall edit it thanks.

pity there isn't a code for "it's an abortion but it works, dunnit?"

That'll be code D1Y

Like that... we used to use picnic... Problem in chair not in code

Ex-IT geek here... now I'm just a part-time nerd... when I'm not working which is quite infrequently at the mo

Not sure its exclusively IT geeks ... I'd say there are lots of geeks. Full stop

What has being Scottish got to do with it?

No code, it is accessible so screwed terminal is an acceptable form of termination.
