  • How to differentiate between high-voltage and low-voltage wiring in underground cable trays

    How to differentiate between high-voltage and low-voltage wiring in underground cable trays

    Low voltage wires work with less than 50 volts, meaning they are suitable for low-power applications, as opposed to high voltage wires which work at voltages higher than 1,000 which are meant for heavy-duty power transmission. These two cable types serve distinct purposes in power transmission and distribution, with. Voltage, measured in volts (V), represents the electrical potential difference between two points in a circuit.
