Fla. Admin. Code Ann. R. 25-6.046 - Voltage Standards
(1) Each utility
shall adopt standard nominal voltages conforming to modern usage, as may be
required by the design of its distributing and transmission system for its
entire service area or for each of the districts into which its system may be
divided.
(a) For service rendered to customers
whose principal consumption shall be for lighting and/or residential purposes,
the voltage at the point of delivery shall not exceed 5% above or below the
standard voltage adopted.
(b) For
service rendered principally for industrial or power purposes, excluding
residential purposes, the voltage at the point of delivery shall not exceed 7
1/2% above or below the standard voltage adopted.
(c) Sudden changes in voltage that exceed 5%
of the standard voltage and occur more frequently than two times per hour, or
changes of 2 1/2% that occur more frequently than once per minute shall be
limited to magnitudes and frequency of occurrence compatible with the
customer's requirements.
(d) The
limitations in paragraphs (a), (b) and (c) may be modified for cases in which
the customer specifically agrees to accept service not meeting the specified
limits.
(2) Where the
utility's facilities are reasonably adequate and of sufficient capacity to
carry the actual loads normally imposed, the utility may require that the
equipment on the customer's premises shall be such that the starting and
operating characteristics will not cause an instantaneous voltage drop of more
than 4% of the standard voltage, measured at the point of delivery, or cause
objectionable flicker to other customers' service.
(3) Variations in voltage in excess of the
limits specified above caused by service interruptions, action of the elements,
temporary separation of parts of the system, infrequent and unavoidable
fluctuations not exceeding five (5) minutes duration, operation of the
customers' equipment at low power factor, unbalanced loading, or other causes
beyond the control of the utility shall not be considered a violation of this
rule.
