NOTES:

Wattages listed are approximate. Check your equipment for actual wattage.

Equipment with unusually high *START-UP WATTS are listed. For start-up of other tabled equipment that uses a motor, allow up to 2 times the running watts shown above. For example a 1 HP motor requires approximately 1000 watts of power when running but may require (2.5 X 1000) = 2500 watts or (4.0 X 1000) = 4000 watts to start.

Multiple loads can be used as long as the total load does not exceed 5,500 surge watts or 4,000 continuous watts. Be certain to start the largest loads first.

Output rating in watts is equivalent to volt-amperes at unity power factor (resistive load) and is calculated as: WATTS = VOLTS  X  AMPS DRAWN. for example a 120 volt device which is rated on its nameplate to draw 2 amps will need (120 VOLTS) X (2 AMPS) = 240 WATTS OF POWER. 1 KW = 1000 WATTS.
