The amount of starting current depends on thetype of motor and its use.• Most electrical tools require 1.2–3 times their stated wattage for start-ing.• Loads such as submersible pumps and air compressors require avery large force to start. They need as much as 3–5 times the wattagestated on the nameplate in order to start.If the wattage is not given for a particular tool or appliance, it can becalculated by multiplying its voltage and amperage requirements:Single Phase: VOLTS x AMPS = WATTSThree Phase: VOLTS x AMPS x 1.732 x 0.8 = WATTS4.2 Indoor InstallationIf the generator must be installed indoors, adequate ventilation orexhaust hoses must be provided. When venting exhaust fumes, makesure the exhaust piping is large enough to prevent excessive backpressure to the engine. Back pressure reduces engine efficiency andmay cause the engine to overheat.Exhaust gas from the engine contains poisonous carbon monoxidegas; exposure to carbon monoxide can cause loss of consciousnessand may lead to death. Never run the generator indoors or in anenclosed area unless adequate ventilation, through such items asexhaust hoses or fans, is provided.When installed indoors, steps to prevent fire and explosion such asproviding a good, earthen ground, removing all flammable materialsnear the generator, and using only electrical cables in good condition,must be observed.
