Answer Posted / kevin fowke
The role of the link in a three phase system is to allow
complete safety isolation of the system for maintenance
purposes. When a 3 phase 4 wire system is used to supply
single phase loads between phases and neutral
disconnecting the neutral could cause a single phase load
to be subject to the same voltage as the phase to phase
voltage. Normally all 3 phases should be completely
disconnected BEFORE the neutral is disconnected. For this
reason a fuse is never placed in the neutral line of a
3phase 4-wire system. In a single phase system the
disconnection of the neutral before the phase line is not
that important.

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
