Generator Handbook

DIRECT CURRENT DC 12 CURRENT FLOWS IN ONE DIRECTION-► Introduction One of the most basic necessities on a jobsite is the need for portable power. The demand for clean, reliable power has made Multiquip generators the most highly regarded brand in the equipment industry. This handbook will cover basic electrical terminology and provide you with the necessary guidelines to help properly size a generator. Basic Electricity A generator converts mechanical energy into electrical energy. Electricity is commonly described in terms of voltage, amperage and watts: ■ Voltage—The electrical pressure, or...

60 OF THE ABOVE REFERENCED CYCLE OCCUR WITHIN 1 SECOND, PRODUCING 60 CYCLES PER SECOND (CPS), OR MORE COMMONLY KNOWN AS A 60 HERTZ SINE-WAVE OUTPUT. TIME SINE WAVE OF THREE-PHASE CURRENT Figure 2 — Alternating Current (AC) and Frequency (Hz) Figure 4 — Three phase power is easier to start and more efficient than a single-phase design. It is not used in residential applications. Phase is a term applied to designate the circuits of an AC system. In the single-phase system, the voltages are in the same time phase in all parts of the system. In the threephase system, the voltages are 120° apart....

Inductive, or capacitive, loads are devices that use an electric motor and require more wattage for start up than continuous operation. Examples of inductive loads include concrete mixers, submersible pumps and air compressors. Next, ask your customer to provide you with the voltage, amperage, and wattage of the tools that will be run off the generator. With this information you can easily determine the total wattage requirement of the equipment being used. This is accomplished by using the power formula. Power Formula Use this formula to size a generator to fit your customer’s needs. Volts x...

Maximum output is 4,710 watts. to the building’s ground source. Electrical Safety “Safety is everybody’s business,” so the old saying goes. This has probably never been truer than it is in today’s workplace. The rise in court cases involving accidents on the job has grown steadily in recent years. Many of these unfortunate accidents could be avoided by having a staff that is properly trained and capable of educating the customer on the potential hazards of operating a piece of equipment. Following are some basic tips for safe operation. Please take the time to read your operator’s manual before...
