...sub-meters at home? There is a sudden huge increase in my meter while there is also a huge decrease in the reading from others meter. but when i called an electrician to check it out they see nothing was tapped with my electrical wirings. I don't have any additional appliance and our usage is the same and i even removed 1 rice cooker because its not working anymore so for what i know our usage must slide down. can anyone please help me?
