Voltage drop is a critical aspect of electrical engineering, referring to the reduction in voltage between the source and the load due to the impedance of the conductors. In Australia, the standards for voltage drop are governed by the Australian/New Zealand Standard AS/NZS 3008.1:2017 and the Electricity Supply Regulations. This paper aims to provide an overview of the maximum voltage drop limits in Australia and the guidelines for ensuring compliance. Lookup the Vccap V sub c factor in AS/NZS 3008
