Operation GP 3800A22 wc_tx000785gb.fm3.3 Determining Power RequirementsThis generator is designed to operate single-phase, 60 Hz appliancesrunning at 120 VAC or 240 VAC. Check the nameplate or labelprovided on tools and appliances to make sure their powerrequirements match the power output of the generator.Some appliances and tools require a surge of current when starting.This means that the amount of power needed to initially start theequipment is larger than the power required to keep it running. Thegenerator must be capable of supplying this “surge” current. Othertypes of appliances require more power than is actually stated on theirnameplate.The information in “Approximate Starting Power Requirements” isoffered only as a general guideline to help you in determining powerrequirements for different types of equipment. Check with your nearestWacker Neuson dealer, or contact the manufacturer or dealer of thetool or appliance, with questions regarding its power requirements.NOTICE: If a tool or appliance does not reach full speed within a fewseconds when switched on, turn it off immediately to avoid damage.Approximate Starting Power Requirements• Incandescent lights and appliances such as irons and hot plates, whichuse a resistive-type heating element, require the same wattage to startand run as is stated on their nameplates.• Fluorescent and mercury lamps require 1.2–2 times their statedwattage to start.• Electrical motors and many types of electrical tools often require alarge starting current. The amount of starting current depends on thetype of motor and its use.• Most electrical tools require 1.2–3 times their stated wattage forstarting.• Loads such as submersible pumps and air compressors require a verylarge 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 = WATTS
