3A-150 HZ PORTABLE GENERATORS POWER REQUIREMENTS 3A3.1 Determining PowerRequirementsThese generators are designed to operate single-phase,50 hertz appliances or tools running at 230 VAC for theG2.1A, G3.3A, G4.6A, and GS4.6A models, and a singlephase voltage of 230 VAC and a three phase voltage of400 VAC for the GS5.7A model. Check the nameplate orlabel provided on tools and appliances to make sure theirpower requirements match the power output of thegenerator.Some appliances and tools require a surge of currentwhen starting. This means that the amount of powerneeded to initially start the equipment is larger than thepower required to keep it running. The generator must becapable of supplying this “surge” current. Other types ofappliances require more power than is actually stated ontheir nameplates.The chart below is offered only as a general guideline tohelp you in determining power requirements for differenttypes of equipment. Check with your nearest WACKERDealer, or contact the manufacturer or dealer of the toolor appliance, with questions regarding powerrequirements.• Incandescent lights and appliances such as ironsand hot plates use a resistive-type heating elementand require the same wattage to start and run as isstated on their nameplates.• Fluorescent and mercury lamps require 1.2 – 2 timestheir stated wattage to start.• Electrical motors and many types of electrical toolsoften require a large starting current. The amount ofstarting current depends on the type of motor and itsuse.• Most electrical tools require 1.2 – 3 times their statedwattage for running.• Loads such as submersible pumps and air compres-sors require a very large force to start. They need asmuch as 3 – 5 times the wattage stated on theirnameplates in order to start.If the wattage is not given for a particular tool or appli-ance, it can be calculated by multiplying its voltage andamperage requirements:VOLTS x AMPS = WATTSCAUTION: If a tool or appliance does not reach fullspeed within a few seconds when switched on, turn it offimmediately to avoid damage.CAUTION: When starting loads, DO NOT exceed two(2) times the given Continuous Current rating for modelG2.1A, or one-and-one-half (1 1/2) times for all othermodels, as damage to the generator may occur. SeeSection 2.1Generator Specifications.3.2 Outdoor InstallationPlace the generator in an area where it will not beexposed to rain or snow. Make sure it is positioned onfirm, level ground so it will not slide or shift. Positionengine exhaust away from areas where people may bepresent.If operating the generator inside a tunnel or deep trench,make sure there is adequate ventilation. Precautionssimilar to those required when operating indoors may benecessary.The surrounding area must be free of water and moisture.All components must be protected from excessivemoisture.3.3 Indoor InstallationIf the generator must be operated indoors, adequateventilation or exhaust hoses must be provided. Whenventing exhaust fumes, make sure the exhaust piping islarge enough to prevent excessive back pressure to theengine. Back pressure reduces engine efficiency andmay cause the engine to overheat.WARNINGExhaust gas from the engine contains poisonouscarbon monoxide gas; exposure to carbon monoxidecan cause loss of consciousness and may lead todeath. Never run generator indoors or in an enclosedarea unless adequate ventilation, through such itemsas exhaust fans or hoses, is provided.When operated indoors, steps to prevent fire and explosionsuch as, providing a good earthen ground, removing allflammable materials near generator, and using onlyelectric cords in good condition, must be observed.
