The meter tallies the quantity of electricity utilized in a home in gadgets of kilowatt hours (kwh). The full boom in the number of kwh from one month to the following is the number utilized by the electrical software in your invoice.
The solution is to put in arc fault circuit interrupts or afcis. Only afcis can save you this form of hazard.
