Someone who used to work on a cable system in the past has told me this:

'To be honest, the overhead one was far better - as the underground one suffered from subsidence, with the entire estate slowly sliding further down the hill - pulling wall boxes off houses and dragging them under ground, and even snapping cables.'

Does the modern system have the same problem? You'd think it would, but i've never heard of any incidents.

He also said that their system used 60 to 65V (said to be the same as the UK telephone system) Is this enough to give you a bad electric shock? What does the modern day VM system use?
