3.6.2 - Mechanical Interlock Kit on a Separate Manual Transfer
Switch
When a mechanical interlock kit (MIK) cannot be installed directly on the main panel, a
separate manual transfer switch (MTS) is installed on the main breaker, and the MIK is then
installed on the MTS, as shown in Figure 3-22 .
The MIK is installed on the MTS panel, allowing either the main MTS breaker or the H6 inverter
standalone breaker to be switched ON, but never both.
