Essential Circuits

As a Backup Power System owner, it is important that you clearly identify the circuits in your building that are "essential" to you. Because the Backup Power System is equipped with an Automatic Transfer Switch, your selection of essential circuits will be transferred to the Backup Power System within 15 seconds (+/- 5 seconds).

It is important that your installer understand which circuits you want to include as "Essential Circuits". Depending on the power consumed by these circuits, most or all of them

can be switched to the Backup Power System for the duration of normal power interruption.

The essential circuits are gathered in a special circuit breaker box, referred to as the Essential Circuit “sub- panel”, that is connected by conduit to the transfer switch. This breaker box is provided by the installer because it allows him to use the brand that is most compatible with your existing electrical service components.

The wattage reference guide shown in Figure 3 will assist you with your decision-making process. It provides the wattage used by many ordinary household devices. Use it as a guide when selecting your essential circuits. Review this information with your installer and ask about any technical considerations that might affect the cost of your installation.
