This could be tricky to upgrade...

Octopus · Aug 22, 2017

Been doing a partial EICR today due to a muppet changing a fuseboard, no certs, no invoice, very shoddy installation flagged by a visiting air conditioning engineer!

This is a picture of the service head ............. the main earth needs upgrading to 10 or preferably 16mm - but is it possible?

This is the CU end of the gas bonding!

Thoughts?

I'm with @Richard Burns, if it can be 'winkled' it should be 'winkled'!

I like the idea of the three 6mm in parallel , but im not sure how you work out that it would be the equivalent to a 16mm , i don't think you can just say 3 x 6 =18mm

Why?

You can just times it by three, the calculation for csa only changes by adding n which is number of conductors.

I done a pic because can't find all the symbols. Diameter of a 6.0 conductor approximately 2.764mm

That is great and much appreciated - the main question though Westward10 is, how did you spell 'bunch' the first time to get it wrong enough to need tippex!
