What voltage can a low-voltage distribution box connect to
A low-voltage distribution panel is the assembly that receives low-voltage power, then routes it through protective devices to downstream loads. You must make safety your top priority when working with low voltage distribution boxes. Primary distribution lines carry this medium voltage power to distribution transformers located near the customer's. In European countries the standard 3-phase 4-wire distribution voltage level is 230/400 V. Many countries are currently converting their LV systems to the latest IEC standard of 230/400 V nominal (IEC 60038). A poorly matched panel can lead to nuisance tripping, failed inspections, and costly downtime.
