                              zone 1 is increased to 1.20 m (701.32.3 (ii) (b))

                       zone 1 is increased to 1.20 m (701.32.3 (ii) (b))
     Notes:
     - All low voltage circuits either serving the location or passing through zones 1
      and/or 2 but not serving the location must have additional protection provided
      by  one  or  more  RCDs  that  have  a  rated  residual  operating  current (I   )  not
                                                ∆n
      exceeding 30 mA (701.411.3.3).
     - Providing all final circuits of the location have additional protection, meet the
      requirements for automatic disconnection and the installation is fitted with
      effective protective equipotential bonding, then supplementary equipotential
      bonding may be omitted (701.415.2).
