RECOMMENDATIONS SINGLE PHASE POWER PLANT WITH PHASE CHANGER IS ECONOMICAL WHERE DISRUPTION OF ONE PHASE BY EB IN PRACTICESINGLE PHASE POWER PLANT WITH PHASE CHANGER IS ECONOMICAL WHERE DISRUPTION OF ONE PHASE BY EB IN PRACTICE EB METER CAPACITY SHALL BE 20AMPS PER PHASEEB METER CAPACITY SHALL BE 20AMPS PER PHASE COST OF PHASE SELECTOR SWITCH CAN BE RETRIEVED WITHIN ONE MONTHCOST OF PHASE SELECTOR SWITCH CAN BE RETRIEVED WITHIN ONE MONTH

RECOMMENDATIONS THREE PHASE POWER PLANT IS ECONOMICAL IN URBAN AREAS WHERE CONTINUOUS 3PHASE POWER SUPPLY IS AVAILABLE.
