Under NEC Article 230, how many service disconnects are required for a dwelling?

The requirement outlined in NEC Article 230 specifies that a dwelling must have at least one service disconnecting means. However, this article also permits the installation of two or more disconnects as long as they are grouped in a single location. This flexibility allows for additional disconnects to be installed for the convenience and safety of the occupants, as long as they comply with the requirements set forth in the code.

This grouping requirement is designed to promote accessibility and ensure that anyone can easily locate and operate the service disconnects in the event of an emergency or maintenance situation. Therefore, while a minimum of one service disconnect is mandated, the option for multiple, grouped disconnects enhances safety and operational efficiency.
