United States

We believe that electrical safety begins with good codes enforced uniformly across the nation. But how uniform are we? America is as diverse in its adoption and enforcement of electrical codes as it is with its geography, political alliances, and people. From the mandatory state-wide enforcement of the California Electrical Code to the home rule state of Mississippi, our states and local jurisdictions all have their own ways of enforcing the National Electrical Code.

Note: Some states, like Arkansas, the NEC is adopted by the state and is required to be adopted and enforced by all jurisdictions. Other states, such as Alabama, the NEC is either adopted by the state, often for state-owned buildings, but local jurisdictions are allowed to adopt their own codes; or the state does not adopt any version of the NEC and all adoptions and enforcements are left to the local jurisdiction.

Every state has its own timetable when it comes to adopting the latest version of the NEC. Some states, like Massachusetts, adopt the NEC at the beginning of the code cycle year, such as January 1, 2008 for the NEC-2008. Others adopt the new code throughout that first cycle year, with June 1 being a popular date for the states to begin enforcement. Another trend is for a state to wait until the beginning of the next year of the cycle (2009 for the NEC-2008) to begin adoption proceedings.
