Identification of Power Leakage and Protection of Over Voltage in Residential Buildings
International Journal of Electrical and Electronics Research, 2022 In many residential buildings the electrical wires of individual houses are laid in the same conduit pipe and some mistakes could be made in identifying similar coloured wires when they are laid in same conduit pipe. Most of the faults are caused by the neutral interconnection in the wiring system.
