What Is a Transfer Switch?
Without a transfer switch, you must manually hook your generator to the equipment you wish to power, which is time-consuming, inefficient, and unsafe. A transfer switch automates the entire process, granting you access to power in predetermined circuits (emergency power, critical equipment, etc.) by the use of either a switch in the manual switch or the process can occur instantly with an automatic switch.
How Do Transfer Switches Work?
How exactly your transfer switch operates differs slightly depending on whether you are using an automatic or manual transfer switch.
How Does a Manual Transfer Switch Work?
A manual transfer switch operates by isolating determined circuits you want to be powered in the event of an outage. These circuits are isolated using a “make and break” system that when operated, swaps your grid power for generator power. By applying this make/break system, you avoid currents and ACRs that can occur without the break, making a transfer switch exceptionally safe in addition to much faster than operating a generator without the switch. Each connected circuit (which is chosen at the time of installation) is protected individually with surge protectors that comes as a part of your manual transfer switch product.
How Does an Automatic Transfer Switch Work?
An automatic switch operates in much the same way, only the process is entirely automated. In the event that your business loses power, the automatic switch will instantly change your supply from grid to generator, with less than a second of interruption in your supply of power. Automatic systems accomplish this by consistently monitoring your grid power supply. When any interruptions occur, whether due to storms, line damage, or any other source, the switch breaks the connection with the grid power and establishes generator power. This is faster and more efficient than a manual system, and these switches are frequently seen in large-scale commercial operations and sensitive businesses like healthcare facilities.
