ANSI PGMA G300-2018 pdf free download – SAFETY AND PERFORMANCE OF PORTABLE GENERATORS.
This standard applies to 15 kW or smaller; single phase; 300 V or lower; 60 hertz; gasoline,liquefied petroleum gas (LPG) and diesel engine driven portable generators intended formultiple use and intended to be moved, though not necessarily with wheels. Permanentstationary generators, 50 hertz generators, marine generators, trailer mounted generators,generators in motor homes, generators intended to be pulled by vehicles, engine driven weldingpower sources and portable generators with AC output circuits that are not compatible withNEMA receptacles are not covered.
2Definitions
Air change rate
Airflow in volume units per hour divided by the volume of the space on which the air changerate is based in identical units (normally expressed in air changes per hour [ach]) , in accordancewith ANSI/ASHRAE 62.2-2016.
co analyzer
The CO analyzer shall be a continuous gas analyzer with a data sampling rate of at least 1 Hz inaccordance with 40 CFR 1065.250, except that the “Complete system rise time(to-9o) and falltime(too-1o)” shall be in accordance with 40CFR 1065.308 for system rise time(tvo-9o) only. Therequirements for system fall time (too-1o) are not applicable.The CO analyzer data shall be timealigned to account for the transformation time.
The initial installation verification tests outlined in 40 CFR 1065.308 may be performed in thetest chamber, using the same length of transfer tube that will be used in the test room.
For the purposes of this standard, the transformation time is defined as the overall system
response time to any step change in input, which is the average of the time to reach 90% responseto a step increase,to-90, or to a step decrease, t1o0-10.
NOTE The transformation time includes both the analyzer response time and any transport delay.Therefore, the Coanalyzer system data needs to be time aligned to the actual CO concentration at the time of portable generatorengine shutoff, ensuring that the portable generator complies with the acceptance criteria.
Enclosure Any surface or surrounding structure that prevents access to parts that may involve a risk ofelectric shock to persons.
Engine
An internal combustion device that converts fuel into mechanical power.
Guard
Any surface or surrounding structure that prevents access to parts that may involve a risk of injury to persons due to mechanical or thermal hazards.
Live part
A conductive part intended to be energized in normal use that may pose a risk of electric shock
Load
An electrical demand expressed in watts; purely resistive.
Lubricants
The portable generator shall be tested with lubricants recommended by the manufacturer.
No load frequency
The measured frequency of the output voltage while no load is applied to the unit.
Normal operation
Operation at any load from no-load to rated wattage, within the rated ambient conditions for the portable generator.
Ordinary tools
Ordinary tools are defined as the following: screwdrivers (slotted and Phillips head), pliers (standard, needle nose and locking pliers), hammers, awls, wrenches, and tools supplied with the portable generator. All other tools are not considered ordinary.
Portable generator
An engine-driven device that converts mechanical energy into electrical energy and is intended to be movable to supply temporary electrical power.ANSI PGMA G300 pdf download.
