The sequence tables below apply for transfer switching equipment with electronic module
(3KC8) and 3KC4 transfer switching equipment with an appropriate, separate transfer
switching controller.
13.1 Transfer between two sources with one outgoing load
Transfer with T1 (kVA) = T2 (kVA)
The transfer switching equipment can be used for transfer between 2 sources with equal
power (T1 (kVA) = T2 (kVA) and with an outgoing load. The 3KC8 series offers the ideal
solution both for network / network applications as well as for network / generator
applications.
