Notes:
1. These clearances are each Electricity Entity’s minimum requirements, additional separation may be required by
    the Service Owner. The greater of the separation requirements shall apply.
2.    Where the above tables does not list a separation requirement for a particular underground service type, the
      following minimum separation from electricity entity electrical assets shall apply:
         LV = 100 mm
         HV = 300 mm
3.    Compliance with these minimum separation requirements does not guarantee that issues such as Earth
      Potential Rise (EPR) and Low Frequency Induction (LFI) are managed, where these issues need to be
      managed, advice will need to be sought from an RPEQ Engineer
4.    All separation distances are measured from the exterior surface of the conduit / cable not centrelines or inner
      wall surfaces.
