After some repairing at my house an electrician made an error and didn't
connect a neutral on a circuit breaker that was sourcing some electronic
equipment I have (router, switch, alarm).

The repair work was done on Friday and on Sunday, when I tried to access the
network I found out that all the electronic equipment was damaged and not
firing up (the PSU I suppose).

At first sight, it seems that if the neutral is not connected we wouldn't
have a diff of potential so I don't see how the equipment could be damaged
but live & earth were ok so I wonder if anyone can explain to me if the lack
of neutral could have been the cause.


** A disconnected neutral would normally result in no AC power on that
circuit as the earth conductor is not used for carrying load current.

Only if the neutral conductor were common to more than one phase can a
damaging over voltage exist. This may sometimes be the case in the USA, but
is not permitted in 240 volt countries for domestic installations.
