Case 1. Cable buried underground.


Case 2. Cable NOT buried underground.

  • There seems to be no opposition to the competence argument then? During my life I have been exposed to many potentially fatal electrical and RF situations. So far they have failed to kill me in any meaningful way. Thus I think it fair to suggest that competence is a solution to all of the "problems" being discussed above. Simply make sure a tool is required to get at the potential danger. Job done.


    A slight aside. Bristol is one City where the "electric scooters for hire" are being tried out on an experimental basis. If you want an accident waiting to happen (and quite a few have) this is the place to look. I was under the impression that a driving license was required to use one, but judging by the age of many users it is being ignored. The standard of roadcraft demonstrated is exceptionally bad, and driving a car or van is now a constant danger of watching out for even more idiots than before. The roads no longer have room for multiple wheeled vehicles, in many places, the lanes are too narrow having been taken for bus lanes, cycle lanes, bus stops,  and any other prevention of driving known to man. Do not come here, much of the traffic is stationary, the latest "anti-pollution" measure! They have also invented something called a "Bus Gate", which is unknown elsewhere but distributes fines at a very high rate. It is intended to be a bus-only entrance to parts of the City centre, (bus being: taxi, bicycle, motor bike, electric scooter etc). The is nothing except a road marking yards into the area to warn you of this wonderful new feature! They just want your money of course.
