How does an automatic transfer switch work in a home?

Normally, electricity flows from the utility to your home’s main electrical panel, where it powers all your circuits. Automatic transfer switches act as the “brain” of your entire electrical system. Once installed, they can automatically switch between electricity coming from your utility and generator power.

Can a load center be an automatic transfer switch?

Instead of installing an automatic transfer switch AND a sub-panel, a load center combines them into a single unit. Load centers are ideal for standby generators powering small homes with 50 to 100-amp inbound service. Your electrician simply connects the load center to 8-16 mission critical circuits.

How is the availability of multiple automatic transfer switches improved?

Availability of multiple utility service systems can be improved by adding a standby engine-generator set capable of supplying the more critical load. Such an arrangement, using multiple automatic transfer switches, is shown in Figure 3 . Reference: ELECTRICAL ENGINEER’S PORTABLE HANDBOOK – ROBERT B. HICKEY, P.E. ( Purchase book at Amazon)

How is the automatic transfer switch ( ATS ) maintenance?

The automatic transfer switch (ATS) is a critical system component of the emergency power supply system (EPSS), and proper maintenance of an ATS depends on the type of switch and its position in the critical power infrastructure. Imagine losing power during a natural or human-made disaster due to incorrect sensing or time-delay function.

What causes an automatic transfer switch to fail?

Imagine losing power during a natural or human-made disaster due to incorrect sensing or time-delay function. Or, the result of a maladjusted ATS control panel. A large percentage of automatic transfer switch failures are attributed to preventive maintenance.
