Understanding 30 Amp Transfer Switches
What is a 30 Amp Transfer Switch?
A 30 amp transfer switch is an electrical device used to switch power between two sources, typically between utility power and a generator or inverter. This switch ensures that power is safely and efficiently provided to your appliances or systems without the risk of back feed, which can damage equipment or pose safety hazards.
How Does a 30 Amp Transfer Switch Work?
When connected, a 30 amp transfer switch monitors the availability of power from two sources. If utility power is available, the switch connects the load to the grid. If the utility power fails, the switch automatically or manually redirects power from the generator or inverter to the designated circuits.
