What does the NEC® help to protect against?

The National Electrical Code (NEC®) primarily aims to protect against hazards arising from the use of electricity. Its regulations and guidelines are designed to ensure safe electrical installations, thereby minimizing risks such as electrical shocks, fires, and equipment malfunctions. By establishing standards for wiring methods, materials, and installation practices, the NEC® helps to create a safer environment for both individuals and properties.

While the other options may have relevance in broader contexts, they do not directly align with the primary focus of the NEC®. Financial loss, environmental pollution, and systematic failures may be mitigated through various regulations and industry standards, but the NEC® is specifically tailored to address electrical safety and prevent accidents related to electrical systems.
