### Who issues the Low Voltage Electrician (ICC G21) license or card in Nevada?

It comes from Electrical Safety Professionals (ESP), which runs the ID card program for Las Vegas, Clark County and Reno, after an ICC exam. Buying a package here does not register you or make you eligible; the board approves you first, and the exam vendor schedules the test.

No. Nevada licenses electrical contractors through the NSCB (C-2), but individual electricians carry an Electrical Qualifications ID card required by Las Vegas, Clark County and Reno, issued by Electrical Safety Professionals after an ICC exam.

### Which NEC edition should I study?

The one named for the ICC exam you book. ICC offers its national electrician exams in more than one edition, so check the exam title in the ICC catalog, then pick the package for that code year.

### Are these the real exam questions?

No. Licensing exam questions are confidential. The courses and practice exams are original material written to the same subjects and format, with explanations that point to the reference section.

### How do the books and courses arrive?
