Section 600
Section 600.220
Interruptions of Service
a) Each utility shall make all reasonable efforts to prevent
interruptions of service. When interruption occurs, the utility shall
re-establish service with the shortest possible delay consistent with general
safety and public welfare. The Commission shall be notified promptly if
service is interrupted for a period of 12 hours or more in any major portion of
the distribution system.
b) Whenever service is to be interrupted for the purpose of
working on the system, this work shall be done at a time which will cause the
least inconvenience to customers and those customers who will be most seriously
affected by such interruption shall, so far as practical, be notified in
advance. The utility shall also notify the proper officer of the fire
department at least 6 hours in advance, if at all possible, as to the extent of
the interruption. At the completion of repairs, the same officer shall be
notified that service has been restored.
c) Each utility shall keep a record of all interruptions
affecting service to the entire system and to any major portion of the
distribution system. This record shall show the date, time of day, duration,
extent and cause of the interruption.
