Safe distance between high-voltage wires and quarry

Distance between high voltage conduit and low voltage conduit

 · By the same token, "low" voltage means under 50 volts but also includes telephone wiring which DOES have a line voltage component as the ringing voltage is generally between 80 and 130 volts. Then there is "data" wiring which includes antenna, cable TV, Ethernet and various other usages. At any rate, there is no prescribed minimum distance ...

What is the safe distance of living near high voltage power lines?

Most of the safety legislation around power lines are included in patch of land on both sides of the HT power line. This is called "Right of Way". Right of way is an allowance of land around the power lines where no human habitation should be allowed. In most cases, it is the land 20-23 metres on both sides of the HT power transmission line.

Determining Safe Distances from Electrical Hazards

Restricted Approach Boundary – The Restricted Approach Boundary (RAB) is identified as the "distance from an exposed energized electrical conductor or circuit part within which there is an increased likelihood of electrical shock, due to arc-over combined with inadvertent movement". Best practice is to stay 12" or more away from the hazard.
