Selecting The Right Generator
The power output of a generator is generally given in kvA (kilovolt Amps). This is the theoretical capability of the generator and is normally more than the actual usable power available measured in watts or kilowatts which is usually 80% of the kvA rating.
To calculate the size of generator required add together all the power requirements in watts of all tools and appliances. For occasional or Intermittent demands the total power required may match the available supply from the generator. For continuous applications such as heating and lighting the demand must not exceed 60% of the generator capacity.
Most electric motors require a starting current at least three times in excess of their running current. It is important not to switch all loads on together as this will activate overload trips or blow fuses.
Most generators are not suitable for running voltage sensitive electronic equipment such as computers and hi-fi equipment. The voltage produced by the generator is in direct proportion to the engine speed. (Please note, increasing the engine speed does not increase the amount of power produced by the generator and will only result in damage to equipment or potential injury to the operator).
Generators are available fitted with an AVR (Automatic Voltage Regulator). Many generators are available with the option of 110v output CTE (Centre Tapped Earth) for reduced risk of electric shock. For these and other specific requirements contact your nearest Lord Hire Centre.
