The main purpose of a manual transfer switch is to be able to utilise two sources of power without having to rewire a building. Both sources of power are connected to the switch and when the mains power fails the generator is turned on and the switch is positioned to allow the generators power to flow through the wires. At the same time the manual transfer switch isolates the main line so that there can be no feedback current. This could be lethal for workers on the line as they expect it to be dead. The unit has been designed to be simple to install and use. The manual transfer switch needs to be installed in a protective panel to keep it out of the weather. There is an option available to have a window fitted to the panel so that the user can see whether the switch is on or off.
