Hi
Customer noticed the insulator attaching one of the overhead cables was about to come away from building. They had the lines company remove the pole fuse . I\'ve refixed the insulators and will put a new point of entry on .I\'ve also moved the position by 2 meters or so to improve separation .
Being mains work assume i will need an inspection , or is it maintenance and not requiring inspection .
It is in the Mangawhai area , anyone recommend an inspector for that area ?

So you\'ve replaced a fitting (an insulator) and in the process you\'ve relocated some conductors \"to facilitate the replacement of a fitting\".
As long as the relocation is minor, eg to find adequate fixing or provide adequate separation; that fits under ESR 6A(1)(b); so is classified as low risk PEW . Though 2 m ids probably pushing the limit, the provision is really about where the replacement fitting has a different size and / or terminal layout that requires minor relocation or extension of conductors to get to the terminals.
If the \"new\" mains entry box is also a replacement it\'s also low risk. But if there never was one, just eg conduit \"tails\" directly connected to the open pair o/c conductors; then adding a mains box would be installation work and mains work, so high risk.

ESRs only require inspection for high risk PEW; so you may well be OK on that front. However some networks have their own extra requirements, and there\'s no question that replacing a mains entry includes a significant risk of polarity reversal; so understandable if they want an inspection.
