A generator installation must only be carried out by a professional who is knowledgeable and experienced in this field. Essential criteria for successful installations include:

  • Necessary ventilation.
  • Electrical connections to be carried out by a qualified experienced electrician.
  • Phase balancing is important on a 3-phase unit, as unbalanced phases can cause damage to the Generator.
  • The set must be properly earthed.
  • The unit must be tested on load to ascertain that the set is of sufficient size to take full load.
  • It is important to use the correct, suitably sized cables between the Generator and the main distribution board. Cables that are too light are dangerous and will cause damage.
  • Electrical motor loads are an important part of any installation such as a factory, a garage, a supermarket or restaurant with refrigerators and exhaust fans.  It is absolutely essential that a proper professional assessment be done by a knowledgeable electrician.
  • Electrical motors draw many times the rated running current (amps) to start up. Single phase 230V motors can draw up to seven times more that the running current just to start.
  • Three phase 380V motors also draw substantially more than their rated running current to start up.  The situation also changes according to requirements, from direct online starting too automatic star/delta installations. Motor starting currents are sometimes severe and as a result are critical on electrical motor-driven borehole pumps. The same applies to motors on compressors etc.



  • All PTO Generators are mounted on a 3-point lifting frame and come complete with gear box with a Ratio of 3,49:1, that helps with the low revs on the tractor.  The tractor will run at about 430 rpm.
  • The Metering panel comes with 3 x Amp Meters, 1 x Volt Meter with selector switch to check Voltage between 3 and single phase, a Frequency Meter to make sure you get the alternator turning at the right speed and a Circuit Breaker.
  • The panel is mounted on top of a Lintz Alternator, which is top quality and is manufactured in Italy.
