What is the NEC, and who is Spark for?

The National Electrical Code (NEC) is the standard electrical installations are inspected against in nearly every U.S. jurisdiction. It's roughly a thousand pages of dense rules that change every three years.

Spark is built for the people who actually have to work from it — journeyman and master electricians, apprentices studying for the license exam, estimators sizing a job, and inspectors double-checking a call. Anything that's faster than flipping through the codebook one-handed at the top of a ladder.
