Home / Neutral wire connection of secondary distribution box
According to NEC Article 250, both the neutral and ground wires must be connected only in the main panel or at the first service disconnect. The installation of the neutral wire in the distribution box is a crucial part of the electrical system, which is related to electrical safety and system stability. Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers.
