Want to ask, are there anyone who is able to do internal power audit for home? My house power usage is around 1300 to 1500kwh every month.
My concern is, to know if the internal wiring cabling is done properly; worry that the high consumption could be due to poor cabling work.
I think you can do a quick assessment on your own first , only when the figure deviated too much away only you engage external party. To assess, just do the following :-
1) list down all your house appliances
a) AC ( kW rating ) x qty x hour of usage / day
b) Refrigerator ( kW rating ) x hour of usage / day
c) rice cooker ( kW rating ) x hour of usage / day
d) washing machine ( kW rating ) x hour of usage / day
e) TV ( kW rating ) x hour of usage / day
f) iron / electric kettle / oven ( kW rating )x hour usage /day
list down all you can
2) After that sum the kWh usage per day up x 30 days .
If the figure come close to 1300~1500 kWh, then nothing wrong . If the deviation too much, then yes, something wrong but it shouldn’t be internal wiring issue but more on illegal tapping after your TNB meter .
