[QUOTE="Tony S, post: 481163, member: 20864"] A picture of the over head line (OH) would be good. Looking at the outgoing cable from the meter box looks to be about 25mm², given the distance involved far too small. Replacing them isn’t going to be cheap. For OH lines hard drawn copper (HD) is needed as it has to support its own weight between poles. The strange thing with HD is its overall size, 50mm² is rolled and compressed so it fits in 25mm² terminals. Now the down side is HD is a pig to work with, it has a mind of its own where it goes. The electrician needs to know how to strain it between poles and then how to bind it to the insulators. Best of luck finding someone that can do the job. OH will be cheaper than under ground as the poles are in place (so long as they’re not rotten). [/QUOTE]
