Problematic Ze........

[richy3333]

With the OPs issue I am certain the fuse was reduced to 80A to allow an increased Ze.

I agree. If the DNO are going to supply an earth they are responsible to maintain it at the correct values.

BTW why is the OP making alterations before assessing the installation is safe to do so? Reg 132.16 specifically makes mention of the supplier?

That is a very good question, a very good question.

The honest answer is that electrics was not the companies primary concern. Surveys were more concerned with pipe runs, equipment positioning and structural loads.

Electrics was seen as running a few cables in to make it all work. This is a very difficult mentality to change, someone had to blow the lid off Pandora's box, but changing it is with the NICEIC Approved Contractor status, CHAS and other safety and quality procedures and schemes in place.

I'm still looking at subbing out the electrical side prior to installation, a pre-condition of sale will be to have all the electrics in place and tested but getting reliable contacts nationally is not easy.

This is all part of the journey when getting involved with entrepreneurial start ups, you have to first find the skeletons, get agreement that they need dealing with then find someone with the will to resolve them.
