Answer 1

Most public service commissions require that the voltage for residential services be held to +/- 5% percent of the nominal voltage as measured at the service point. This ensures the proper functioning of electrical appliances and prevents damage to electrical equipment.

Step-by-step explanation:

Most public service commissions require that the voltage for residential services be held to +/- 5% percent of the nominal voltage as measured at the service point.

For example, if the nominal voltage is 120 V, the acceptable voltage range would be 114 V to 126 V. This requirement ensures that the voltage supplied to residential homes remains within a specified range to prevent damage to electrical equipment and ensure proper functioning of electrical appliances.
