automatically be switched off 10 minutes after the switch is
depressed, or after the switch is depressed a second time.
e) Generator Set AC Output Metering:
The generator set shall be provided with a metering set including
the following features and functions:
2.5-inch, 90-degree scale analog voltmeter, ammeter, frequency
meter, and kilowatt (KW) meter. These meters shall be provided
with a phase select switch and an indicating lamp for upper and
lower scale on the meters. Ammeter and KW meter scales shall
be color coded in the following fashion: readings from 0-90% of
generator set standby rating: green; readings from 90-100% of
standby rating: amber; readings in excess of 100%: red.
Digital metering set, 0.5% accuracy, to indicate generator RMS
voltage and current, frequency, output current, output KW,
KW-hours, and power factor. Generator output voltage shall be
available in line-to-line and line-to-neutral voltages, and shall
display all three-phase voltages (line to neutral or line to line)
simultaneously.
f) Generator Set Alarm and Status Message Display:
The generator set shall be provided with alarm and status
indicating lamps to indicate non-automatic generator status, and
existing alarm and shutdown conditions. The lamps shall be
high-intensity LED type. The lamp condition shall be clearly
