Most public utilities depend on electric power to function, so it is paramount that a constant power source is available. These public utilities get their supply from the public mains and in the case where the public mains fails a back-up power source is necessary to ensure the continuous operation of the public utilities. Switching the public utilities from the mains to the back-up power creates a period of time when the utilities will be without power and the longer the time delay the lesser the efficiency of the public utilities. The stress of manual switching also makes the utilities inefficient. Examples of these public utilities are street lights, traffic lights, water pumps and traffic sign indicators. A device that completely eliminates the stress of manually switching public utilities from the mains supply to the back-up supply is the Automatic Mains and Phase Changer (AMPC). It also greatly reduces the power outage time delay experience during the switching. This paper reports a research that evaluates the relationship between the stress levels during manual load switching and the stress levels using the AMPC for automatic load switching. It also evaluates the relationship between the time lag experienced with the use of the AMPC and the time lag experienced when the switching is done manually.
