Exposed copper wire under the floorboards after rewire

[DPG]

True, but if not fitted there should be a risk assessment to justify it. Which I doubt happens in most cases.

My gripe is more about the stupid "18th edition" naming. You could argue that "17th amendment 3" makes sense for the metal CU that became a requirement then, but if calling it "18th" then what was added if it is not the SPD?

Absolutely. It just causes more confusion calling them 17th or 18th edition units. Doesn't help anybody. Sparkies don't need it, and the average DIY guy probably going to think his work is 18th compliant because it says so on the box.

Just reading the Toolstation flyer that arrived by post offering "18th edtition" Contactum CUs dual RCD without SPD. Really?

So whats the problem?.......

 

[Dave OCD]

another small gripe is the internal tails feeding the RCDs. in the wqy. i usually take them out to wire in the circuis, then refit them after. sometimes i even get them in the right order.

Off topic, but does anyone else sharpie the internal tops of MCB's with the cct details so that you can ident them with the panel off?

I do sometimes number them on the top during an eicr if it's a particularly bad rats nest.
If I'm doing a label print for the outside cover, I normally just do a 2nd label for the bus bar cover inside.

Genuine question, not a challenge.... apart from the expense, does adding a label internally comply with fire retardancy requirements for a type tested unit?

Interesting question!

I would say not a problem, as there are already paper labels on the inside of the consumer unit (terminal labels for earth and neutral bars for example).

 

[DPG]

Strictly speaking I imagine you probably shouldn't add any paper or plastic based labels to the inside of any manufactured product. Not that there would ever be any comeback.

I can only think of issues in really odd cases such as someone sticking a label near mains voltage terminals, and it gets damp and tracks across.

 

[timhoward]

Plenty of 3 phase units have an identical label inside and on the outer cover. Of course they are provided that way by manufacturer so that's a bit different. Just for fun I might try setting fire to a brother label later....
I wouldn't have thought it would provide much fuel for long in a metal unit.

Yeah absolutely. Should be no real world issues.

Mind you, don't use the metallic foil tape

oh you're no fun at all....

so the legend on the B&H packet is a no-no? wrote smoke, but some AI dipstick turned it to smokes. F£G FFS

I doubt that a label makes much difference compared to all the pvc you add when cables are installed.

I think a pedant would probably say that the cables are already accounted for in a type test by virtue of the various standards and compliances, whereas the added label has no known BS EN standards materials, adhesive, ink...

That probably applies to all the screwdrivers I have left in various panels over the years too.
couple of torches have been lost in the same manor I think.
thankfully they have not caused any spontaneous combustion as far as I know!

The opposite applies too (Confession) - I’ve had a neutral link bar for an Mk split load board in my toolbox for years. I first noticed it after a frantic week and thought ‘someone will phone up and say 50% of things aren’t working’. No one ever did!

Maybe they don't have a mobile and the socket for the cordless landline has never worked since you left ?
