As with any "uniform" code, jurisdictions may regularly omit or modify some sections, or add their own requirements sometimes based upon earlier versions of the NEC, or locally accepted practices.

However, no court has faulted anyone for using the latest version of the NEC, even when the local code was not updated.

Those who fail to adhere to well known best practices for safety have been held negligent. This liability and the desire to protect residents has motivated cities to adopt and enforce building codes that specify standards and practices for electrical systems as well as other departments such as water and fuel-gas systems.

This creates a system whereby a city can best avoid lawsuits by adopting a single, standard set of building code laws. This has led to the NEC becoming the de facto standard set of electrical requirements.

Technically, the National Electrical Code is an example of a "uniform code. If you'll recall, in the United States, both the federal government and the state governments are allowed to make laws. Some laws are made exclusively by the federal government such as laws related to monetary policy , while other laws are made by each individual state such as laws related to traffic and the speed limit.

There are some areas of law where it might be helpful to pass federal laws, but the federal government has not chosen to do so, and instead leaves authority to each individual state. In such cases, a "uniform code" is created as a set of "guidelines," and each state can adopt all or portions of the Code as they see fit.

Sometimes, the states or local jurisdictions will adopt the Code with specific amendments.
