Prime Power offers a range of Honda Powered Generators, Robin Powered Generators, Yamaha Powered generators, Ph Basic Series Generators, Builders Work Specs Generators, Diesel series Generators, 4 in 1 workstation Generators, 1 Single Phase Generators and three 3 phase generators.

The current drawn by a motor during ‘starting’ is often specified on the motor nameplate specifications as locked rotor amps (LRA). This current is typically five to six times the full load amps (FLA) of the motor, and as high as ten times FLA for high efficiency motors. This inrush current lasts only until the motor shaft has reached its rated speed, so it is typically of very short duration, perhaps less than one second. To work out KVA required use start current then divide by 2, then divide by 4.2
Example: 42a ÷ 2 = 21a
21a ÷ 4.2 = 5KVA

KVA = Watts
1.0kva x 0.8 = Watts

Watts = KVA
1400W x 1.25 = KVA

Approx 4.2a per KVA

To work out KVA required use start current then divide by 2, then divide by 4.2

Example: 42a ÷ 2 = 21a
21a ÷ 4.2 = 5KVA

* Drills and small saws must be brush type motors with no excess starting load, all other electric motors see your dealer for advice. Electronic welders often take more power KVA to correctly opperate. Check with your welder manufacturer for their recommendation with this type of product.
The above table should be used only as a guide. Product specifications vary from manufacturer to manufacturer.
Prime Power accepts no responsibility for generators chosen purely using this basic guide. At all times you must refer to the manufacturer of the prodct to be operated by a generator for the correct sizing of machines.
