neutral switching of lights

[davek]

Hi all
My niece has just bought a house so asked me check over electrics etc, from a visual was a new flurecent light in itc as tube was going and tatty (she bought it to rent out).so on fitting the lights I notices it was neutral switching. On further investigation the whole house and looks like it was re wire that way. along with several connecter strips as junctions no enclosures. can anyone explain why they would of wired it that way prop done 80-90 or did they just come on there horses lol

You sure there is not a phase neutral polarity mix up at the DB incommer here?

The only way to sort this is to start at the very beginning and trace it right through , you may find by putting 1 thing right it is solved , but this could be making somewhere else reverse polarity , so only way is to trace right through from start..

WHAT.

Is that describing the normal situation? It's difficult to know from the gobbledegook.

I think what he means is that testing between switched live and earth with switch in off position he's getting 240v but when switch is on he gets nothing,this makes sense because with switch in off position he will be getting the live feeding through the lamp from the "neutral" which will drop off when switch is in the on position.
