License types issued

Illinois issues the following electrician license classifications:

Code edition

Chicago Electrical Code (based on NEC with Chicago-specific amendments — Chicago has historically been more conservative than NFPA on some methods). Verify with the City of Chicago Department of Buildings.

What candidates should know about prep

• Chicago Electrical Code historically required EMT or rigid metal conduit for all branch circuits in commercial occupancies — verify current rules.
• MC and AC cable acceptance has expanded but adoption is jurisdiction-specific.
• Confirm which jurisdiction's exam applies before buying state-specific prep.
