Diesel

Diesel generators can serve suitable backup, construction and commercial power applications when sized and installed properly. Compare open-frame and silent-enclosure models by rated continuous kilowatts or kVA, starting capacity, voltage and phase, fuel use and service access. A nameplate’s apparent-power figure must not be treated automatically as usable real power in every load condition.

Before ordering, identify the appliances or motors to run, their starting requirements and the proposed transfer-switch arrangement. Check whether starting batteries, breakers and weather protection are included. A qualified installer should assess connections and grounding. Never operate an engine generator indoors or where exhaust can enter occupied rooms.
