About the ICC Master Electrician (T16, 2020 NEC)
Granted by International Code Council (ICC)
ICC Master Electrician exam T16 (Pearson VUE): 100 questions in 5 hours, open book on the 2020 NEC. The version Pittsburgh steers candidates to, and the same outline and code as Philadelphia's ICC 211 master electrician exam.
Eligibility Requirements
ICC sets no experience requirement for this exam. Philadelphia's Electrical Contractor License needs four years of electrical work for a licensed company (two years of electrical education can count as one) and 8 hours of NEC coursework in the 12 months before you apply. Pittsburgh's Electrical Trade License needs six years of combined experience and education.
On the 2020 NEC (ICC T series)
ICC offers its master electrician exam on four NEC editions: F16 (2014), G16 (2017), T16 (2020) and R16 (2023). This practice exam is for T16 and Philadelphia's ICC 211, both on the 2020 NEC. Much of today's study material is written for the 2023 edition, which renumbered these rules. Every question here cites the 2020 section.

- Pittsburgh requires 8 hours of continuing education in the 12 months before each yearly renewal, from ICC's Preferred Provider Directory or a Pennsylvania UCC-approved provider. Philadelphia renews its license yearly ($202).
Reciprocity
ICC results are not a license, and Pennsylvania has no statewide electrician license. Philadelphia may count licensure elsewhere as proof of experience, subject to approval, but still requires its exam; Pittsburgh's License Officer reviews older ICC versions case by case.
