Question

what is the best way to submit changes to the nec®?
contact the nfpa technical committee
use the form available on the nfpa website
use the form available on the osha website
contact a member of the nec correlating committee

Explanation:

The National Electrical Code (NEC®) is published by the National Fire Protection Association (NFPA). To submit changes to the NEC®, the proper and official way is to use the form available on the NFPA website. Contacting a member of a committee or using a form from another organization (like OSHA) is not the standard procedure. The NFPA Technical Committee may be involved in the review process, but the initial submission should be through the official NFPA - provided form.

Answer:

use the form available on the NFPA website
