ABOUT MANUAL TRANSFER SWITCH OR CHANGEOVER SWITCH:

Manual changeover switch had been in existence for decades. They are used to switch an electric load back and forth between a primary source, such as P.H.C.N., and a secondary source, such as a generator. Transferring power from the primary source to the secondary source is necessary when the incoming power source fails. The transfer switch is also used to switch the source back to public utility power when the power quality returns

BENEFITS OF AUTOMATIC TRANSFER SWITCH OVER A MANUAL TRANSFER SWITCH:

With a Manual Transfer Switch, when the power goes out, you need to start your generator, connect it to the transfer switch (also known as change-over switch)and then switch your house over to generator power. When the utility power is restored you need to switch your house back to utility power, and turn off your generator. But with an Automatic Transfer Switch, everything is fully automatic. When the utility power goes out, the transfer switch signals your generator to start. Once the generator is running the transfer switch automatically connects your home or business to the generator. When the utility power is restored, the transfer switch reconnects your home or business to the utility. Then it turns off your generator and waits for the next power outage. This helps you to save fuel costs and it is much safer because of its user-free operation.

Also, it is comparatively cheaper to the manual change over switch.

A manual 63amps(27 kva) cast change-over switch sells for at least N30,000 while 32amps goes for at least N15,000.
Considering that the automatic changeover it truly automatic and lasts longer, safer, saves fuel usage, and elongates Generator life, that makes it a superior and cheaper choice any day.
