Comment on Code Question of the Day for 04-08-2020.

As always, I appreciate the insight you bring to code clarification. Keep up the good work. Response to this answer provided on 4/9/2020: The answer is no. The NEC does have multiple rules that require qualified persons which is defined in Article 100. Regulating the qualifications and certificates of contractors and electrical workers is beyond the scope of the NEC and is typically handled at the state or local jurisdictional level. The second part of this question is also a jurisdictional issue. Some jurisdictions exempt systems and installations of less than 50 volts from any permit or electrical inspections. The NEC does have rules that pertain to such systems. It's is always a good practice to verify the specific requirements regarding licensing with the local jurisdiction. I would like to add that certain systems that may fall below 50 volts such as: fire alarm systems, fire suppression systems, or fuel monitoring systems, that may fall under the jurisdiction of other codes, such as NFPA 72, and may be under jurisdiction of an authority other than the electrical inspector, such as the Fire Marshall. Depending on the state and local requirements, these types of installations may in fact require state licensure or certification and local permitting and approval for those engaged in that type of work. And as you clearly stated, it's always best to check with your local building department official to verify prior to commencing with the work.

Hi Vaughn,

Thanks for participating and a great point to include with the answer about possibly others that might have jurisdiction beyond the electrical inspector, which is often the case. Thanks.
