How many volts V is the secondary distribution box
Most modern secondary networks are operated at AC rated voltage of 100–120 or 230–240 volts, at the frequency of 50 or 60 hertz. Operating voltage, required number of phases (three-phase or single-phase) and required reliability dictate topology and configuration of the network. Primary distribution lines carry this medium voltage power to distribution transformers located near the customer's. Nearly all spot networks in North America function at a 480Y/277-V secondary voltage. High service dependability and operational flexibility are attained with a spot network supplied by two or more primary feeds via network transformers. The following electrical ratings are typical: As a result of locating power transformers and their close-coupled. The primary distribution system is the backbone of the electrical supply chain, bridging the gap between high-voltage transmission and localized distribution networks. 3 kV to 400 V at the distribution substations.
