Written by GovTribe AI ·

This document contains a generator sizing analysis and recommendation for a federal contract opportunity to rehabilitate water and wastewater systems at Acadia National Park in Winter Harbor, Maine. The analysis evaluates a load consisting of a 3.5 kW resistive load and a 5 HP motor load, and recommends a 25 kW LP vapor generator model RG25 to meet the total peak load of 21.9 kW. The generator is rated at 23 kW with a 1.5L engine and standard RG025 alternator. The analysis confirms the generator selection can handle the starting transients and running loads within specified voltage and frequency distortion limits.

Note: Always consult the generator manufacturer whenever questions arise.

These sizing charts are recommendations based on motor service factor loading for typical continuous duty generators. If you need to call the generator manufacturer, be prepared to tell them the motor KVA code, the service factor amperage, locked rotor amperage, phase, Hz, motor type, etc. This information can all be found in this manual.

Please note that the 2-wire chart is only for PSC (permanent split capacitor) type, 2-wire motors and should not be used for split-phase, 2-wire motors. If using split-phase, 2-wire motors the generator should be 50% larger than that listed for a 3-wire motor.

You must know which type generator you have before using the charts as the required generator size varies by type. Internally regulated generators are also called self-excited. Externally regulated generators are the most common. In addition to the Kw/KVA rating, the generator frequency (Hz, typically 60 Hz in USA) is very important when operating pumping equipment because frequency variations affect pump output in direct relation to the pump Affinity Laws.

Operating under 60 Hz will reduce flow and head while operating over 60 Hz will increase flow, head, HP and amp draw and could overload the motor.

The generator should always be started before the pump/motor is started and always stop the pump/ motor before shutting down the generator. Operating generators at higher elevations or using natural gas a fuel can affect performance, consult the generator manufacturer for their recommendations in these instances.
