ELECTRICITY SAFETY (INSTALLATIONS) REGULATIONS 2009 (SR NO 164 OF 2009) - REG 228

    (1)     An aerial line set out in Rows C to G Column 1 or 2 of Table 228 that forms part of—

        (a)     a high voltage electrical installation; or

        (b)     the supply network of a small gauge railway—

must not, at any time, be closer to an aerial line specified in the same Row as that line than the relevant minimum distance specified in Column 3, 4 or 5 for the relevant Row of the Table for the location of the aerial line specified in Row B in those columns.

    (2)     The nominal voltage of the lower circuit of an aerial line must not be greater than the nominal voltage of the upper circuit of an aerial line.

    (3)     A d.c. traction conductor for a small gauge tram system must not, at any time, cross an electrolysis drainage cable, unless the conductor and the cable are attached to a common pole or support.
