NEC adopted by reference in OBC Chapter 35 (OAC 4101:1-35-01 lists '70-23 - National Electrical Code', with s.210.8(F) Exception No. 2 non-expiring); residential amendments at RCO 4101:8-34-01 (amendments_url). License classes URL is the Dept. of Commerce / Industrial Compliance landing page opened this pass; a deeper OCILB classification sub-page was not separately verified. Permitting runs through certified local building departments; no state-issued electrical permit regime was established, so the permit field is blank.
