Understanding Manual Transfer Switches and their Uses

dark roomDon’t get left out in the dark. Luckily, here’s where Transfer Switches barge in and save the day. Or save power that is. A transfer switch is a device used to maintain power supply in case of outages in power and also spares homeowners from the dangers of improper generator installations.

By definition, a manual transfer switch is linked to the necessary circuits for supplying power during blackouts. A switch like this requires actual man power as for this mechanism to be of use, the owner needs to start the engine manually and wait for it to stabilize its speed. Upon stabilization, the lever on the switch must be thrown into the generator’s position.

This is located beside the main electrical panel. In the instance when a power outage has struck your home, a manual transfer switch comes handy as you just have to crank up the generator and have a single power cord run from the generator to the transfer switch.

With this done, you’ll have the generator running in no time. All you have to do now is select the circuits to power up, flip the respective switches and voila! A backup power for your home or establishments in the midst of a power supply outage.

To determine the size of a manual transfer switch, one should know that it is congruent to the size of the power cord, e.g. for a 20-amp cord, a 20-amp transfer switch is necessary.
