The components comprising the three panels are installed in accor- dance with the specific requirements of the circuit being controlled. Each transfer switch is, therefore, tailor-made to a specific applica- tion.

3.2 Power Panel

The power panel consists of a means for making load, power, and neutral connections. The main contacts and the transfer mecha- nism are all on one steel frame (Figure 12). The actual power con- nections are shown in Figure 13.

Figure 12. Insulated Case Switching Device.

3.2.1 Main Contacts

The main contacts connect and disconnect the load to and from the different power sources. High withstand insulated case switches are the main contacts for the Source 1 and Source 2 power sources in standard, unmodified ATSs. Optional integral thermal and short circuit protection in either or both switching devices is available (Section 3.6). These continuous duty devices are rated for all classes of loads. In addition, they have high dielectric strength, heavy-duty switching and withstand capabili- ties, and high interrupting capacity.

3.2.2 Switch Interlocks (Open Transition Only)

Eaton transfer switches are mechanically and electrically inter- locked to prevent the two sets of main contacts from being closed simultaneously.

3.2.3 Drawout Interlocks

The standard closed transition ATS is not provided with a mechanical interlock. All bypass switching devices are mechani- cally interlocked to the drawout mechanism to ensure that the switching device is always open when connecting or disconnect- ing it from the line and load stabs when in the bypass mode.

All open transition switching devices are mechanically interlocked to the drawout mechanism to ensure that the switching device is always open when connecting or disconnecting it from the line and load stabs.

The switching device will close only in the DISCONNECT, TEST, and CONNECT positions.
