* The transformer is not necessary if:
Normal and Bypass AC inputs are connected to the same source,
and wires cross sections and wires lengths on Normal and Bypass inputs are identical,
and upstream protection is provided by only one switch with RCD (residual current device) for Normal and Bypass inputs.
