1) Regulations require overhead lines to be supported to prevent accidental damage. Support must be sufficient to withstand weather conditions while allowing for high-sided vehicles.
2) Live conductors that are accessible must be insulated or covered to prevent electric shock. Insulated conductors like low-voltage aerial bundled cables may be placed such that they are ordinarily accessible without danger.
3) Developers or other persons erecting buildings or structures near overhead lines must notify the relevant distribution company of their plans. This gives opportunity to make the lines safe before it could become a source of danger due to the proximity of the proposed building or structure.
