Is This Your Exam?

G18

The G18 runs on the 2017 NEC and is the Residential-level ICC electrical exam. Check the jurisdiction guide to confirm whether your city or county requires it, and which exam code they use locally. Use Our Jurisdiction Guide →.

Why Residential-Level Is Different

Residential exams sometimes get treated as "easier" — but failing one still delays your license just the same. The G18 tests the full residential scope of the 2017 NEC, your prep should match it exactly.

MCL's G18 prep targets that scope: the right content, the right depth, without commercial or industrial material you won't see on test day.

Is the G18 exam open book?
