Part VI of Article 230 of the NEC provides the requirements for service disconnects. A concern that threads through these requirements is helping first responders to disconnect the power during a fire, gas leak, or similar emergency.
These requirements, for example, include:
- The disconnect(s) must be in a readily accessible location [230.70(A)(1)].
- You can have a maximum of six sets of disconnects per service grouped in any one location [230.71(A)].
