What Generator Changeover Switches Do

A changeover switch for generator units is an electrical switch that transfers a load of power from the power grid it gets its main supply of power from to a backup generator. It acts as an intermediary electrical relay between power sources and your building’s generator. This process is started whenever there is a power outage or failure of the power grid. Generator changeover switches are usually installed at the same location where backup generators are located, allowing the generator to supply temporary electrical power in the event of the utility power source failing.

How Generator Changeover Switches Work

The main breaker inside either a manual or automatic generator changeover switch transfers your utility power source to a standby generator. Utility power sources and generators cannot be connected at the same time; this is done to stop the utility power from back-feeding into the generator and also stop the generator power from back-feeding into the utility lines.

Generator changeover switches contain multiple circuits. Power loads can be assigned to specific circuits so they can be used for certain applications. However, some power generators aren’t big enough to provide power to every circuit at the same time. If this is the case, using either a manual or automatic generator changeover switch makes it very simple to switch between different loads. Whenever a power outage occurs, having a commercial or domestic generator changeover switch on your premises will make it much easier to manage your power usage and maximise how effective your generator is.

A changeover switch for a generator is designed to switch the power source from the utility grid to a backup generator during a power outage. It works by connecting the generator to the electrical system and disconnecting it from the grid when the generator is operational. When power is restored, the switch automatically transfers the power source back to the grid and disconnects the generator. An automatic generator changeover switch can ensure uninterrupted power supply to essential circuits or the entire home.

Automatic generator changeover switches provide convenience and peace of mind, eliminating the need for manual intervention during power outages. The switch can detect the loss of utility power and automatically start the generator, ensuring a continuous electricity supply that protects sensitive electronics from power fluctuations.

Yes, it’s possible to install a domestic generator changeover switch in your home. This is recommended if you live in an area where power outages are frequent or you require a reliable backup power source. The switch is typically installed near the main electrical panel, allowing for easy connection to the generator and integration with the existing electrical system.

A generator transfer switch is definitely worth it for those who require an uninterrupted power supply during outages. It eliminates the need for manual operation, offers protection to your electrical system and appliances, and enhances safety by preventing backfeeding.
