Where is the automatic transfer switch located?
The transfer switch is installed between a main panel and a sub panel. The main panel connects to the non-essential loads. The sub panel connects to the essential loads. In the event of an outage, the transfer switch will only transfer power to the essential load panel.

What is ATS automatic transfer switch?
An automatic transfer switch (ATS) is a self-acting, intelligent power switching device governed by dedicated control logic. Upon failure of the connected power source, the ATS will automatically transfer (switch) the load circuit to the other power source (if it is available).
Is a transfer switch necessary?
However, the law says that it is necessary to install a transfer switch in order to operate a portable generator. In fact, the National Electric Code has made it mandatory for a power connection to a home to have a transfer switch. A transfer switch is needed for safety too.
How do I choose an automatic transfer switch?
The automatic transfer switch you select should be capable of supplying maximum current for up to 3 or, even more, hours. The current should be carried continuously from the power source. The current ratings usually range between 30 and 400 Amps. It is important that the rating matches the use by the main breaker.
Can you use a 200 amp transfer switch on a 100 amp service?
If you have a generator that is rated for 100A, you should be fine. If the ATS is rated higher, that doesn’t matter. It’s just a switch if you need a 100 Amp before you connect the 200 Amp transfer switch. …
How does an automatic power transfer switch work?
To maintain a continuous supply of power, an automatic transfer switch provides a seamless transition between a primary power source and a secondary or tertiary power source. Combined with a control panel, the switch detects anomalies in the flow of primary power and commands the control panel to start the standby generator instead.
How to calculate the cost of auto transfer switch?
In order to evaluate the cost of maintenance, one must factor in the cost of lost service due to an unplanned failure plus the cost of replacement.

Why is there no transfer switch in solid state ATS?
The solid-state ATS lacks the traditional mechanical transfer switch. Because this unit relies on SCR or transistor technology, sub-cycle transfers are possible. Although there is technically a “break” in load current, the speed of these units prevents adverse effects to sensitive equipment.
What are the different types of automatic transfer switch?
The automatic transfer switch (ATS) is a critical system component of the emergency power system, and proper maintenance of an ATS depends on the type of switch and its position in the critical power infrastructure. There are four basic ATS types: The break-before-make (open transition) is the most common.
When do you need to use a transfer switch?
A transfer switch is a critical component of any emergency or standby power system. When the normal (preferred) source of power is lost, a transfer switch quickly and safely shifts the load circuit from the normal source of power to the emergency (alternate) source of power.
In order to evaluate the cost of maintenance, one must factor in the cost of lost service due to an unplanned failure plus the cost of replacement.
What kind of transfer switch does Eaton use?
