Is it common or even required by regulation that household
electrical wiring have 3 wires including the neutral wire? My
electrician is telling me no and that he will need to charge me
more to install the neutral wire.
2 wire is as other hv said.. live & neutral.. also mean
+ - positive/ negative in easy way..is must die die connect this
two in order to let electricity to go "into" the applicance then "
go back" into the socket..if not the applicance will not "ON"
unless that electrician use other colours to use for live/neatural
lah..
the 3 wire is mostly total green or wid a streak of yellow
line...that is EARTHED.. meaning if short circuit,overloading>
your DB switch will trip(off electricity) thus preventing more
worst situation..
Normal plug use 13amp, some 15amp..then wire come into play,
1.5mm/2.5mm/3.5mm>
Again, i agree wid what other say, ask the current electrician
to F off..get a better electrician.
EDITED:
From socket measure is still 240v bah..just that the 430v is
from the sub generator..(not very sure-but think so, cos if 430v go
in home applicance will up lorry de..)
