    Fast. Targeted. Convenient.

    Our analysis of changes course is based on the IAEI analysis and focuses on industrial applications. This two-day course is for individuals already familiar with the NEC. The course will cover new material, revised material, the reasoning behind the change and the impact this will have on the electrical industry.

    For example: Many of the Articles have made additions which include reconditioning of equipment. Many of these are located in the sections (##.2) of the Articles. The sections point out what equipment is permitted to be reconditioned and what equipment is not permitted to be reconditioned.

    While the current version of the code is the 2023 cycle, not every state adopts the code at the same time so call us to determine which cycle version you need to comply with in your state.

    NTT Training is proud to announce our partnership with the IAEI – International Association of Electrical Inspectors. NTT Training is the only approved training provider to deliver IAEI’s excellent content via streaming Live Internet broadcast (Live Online Training).
