MEB CSA increases.

[securespark]

Does anyone know when changes were introduced in MEB sizes?

Did they come into being in the 14th?

What size did they start at and when were they increased?

I have seen 2.5 on pipework before now - is that the smallest?

What mission are you on Secure??

 

[securespark]

Got ambushed by a retired lecturer in electrical engineering today who insisted on the history of electrical installation from 1882 to the present day...

Wanted to know when 4mm² MEB's went out of standard.

Doesn't he know?He'd have more idea than us young 'uns

 

[securespark]

Yeah, I think he was testing me about how much I knew.

But then I got to thinking: it might be good to know these things anyway!
