ELECTRICITY SUPPLY REGULATIONS - REGULATION 7

Maintenance of insulation

There shall be maintained by the company at each station or sub-station as may
be necessary a leakage indicator of approved pattern and so arranged that the
leakage on each main feeder can be readily ascertained at any time and a
weekly test recorded. If at any time the leakage is in the opinion of the
Director of Electrical and Mechanical Services excessive, he shall require the
company to remedy the same and it shall forthwith be remedied: Provided that
where any part of any electric circuit is connected with earth either in
accordance with these regulations or with the approval of the Director of
Electrical and Mechanical Services, the provisions of this regulation shall
not apply to that part of that circuit so long as the connection with earth
exists. (L.N. 76 of 1982; L.N. 298 of 1982)
