Hello all Experts
I myself have wired two rooms and now trying to install Luminous UPS 1000 in home but found some confusion about single wire or double wire from UPS output to Room's switch board containing three switches one for fan, one for bulb and one for three pin socket.
Single Wire Method
In single wire we attach only positive (hot) wire to three pin and do not attach neutral wire to three pin sho and than insert into out put of UPS and second end would joint with wapda phase (hot wire) it mean we joint two phase in switch board and neutral wire is common which is coming from wapda. Please correct if I am wrong.
double wire Method
in double wire method we attach two wire positive(hot) and negative (cold) wire in three pin sho and than insert into out put of UPS and second end of wire joint with wapda positive (hot) and neutral(cold) in home wiring. In this type of wiring positive and neutral wire are separated. Please correct if I am wrong.
and Last question is that which method is so safe single wire in which neutral wire is common or double wire in both wires are separated. I think single wire is not safe but economical and double wire is safe but a bit expensive.
