When does the exam change to the 2023 NEC codebook?
According to the Massachusetts Board of Electricians, the exam will not change until 7 months after the code book is adopted. Since the 2023 was adopted late, the exam will not change until September of 2023. This means you should still be studying the 2020 NEC and using the 2020 NEC for the exam until late September 2023!
