Licensing Steps

The ES-3 trade examination is one part of the process for qualifying for a New Mexico contractor license in the Low Voltage Special Systems classification.

1. Meet the applicable experience requirement. The individual seeking to serve as the Qualifying Party must have qualifying experience related to the ES-3 classification.
2. Document the required experience. Applicants submit the appropriate work-experience affidavit and supporting information for review.
3. Complete the Qualifying Party application. The applicant must provide the required information for the classification being sought.
4. Receive examination approval. Candidates must complete the eligibility process before scheduling the required examinations.
5. Take the ES-3 trade examination. Candidates must satisfy the trade examination requirement for Low Voltage Special Systems.
6. Complete the Business and Law requirement. New Mexico Qualifying Party applicants must also satisfy the applicable Contractor Business and Law requirement.
7. Complete the contractor company application. Once the Qualifying Party requirements are satisfied, the business entity submits the applicable contractor license application and required supporting documents.

Passing the ES-3 trade exam alone does not create an active contractor license. The qualifying individual and the contractor business have separate requirements within the New Mexico licensing process. This Ultimate package includes Application Service to support the licensing paperwork associated with moving through those steps.

State Requirements

The New Mexico ES-3 Low Voltage Special Systems classification requires two years of experience. The classification applies to qualifying interior and exterior special systems, cabling, and interconnections at commercial and residential locations operating at 50 volts or less.

The authorized scope includes telecommunications systems, fire alarm systems, CATV systems, audio and visual systems, security systems, door and gate control circuits, temperature-control circuits, and other low-voltage specialty systems operating within the classification's voltage limitation.

The scope also includes qualifying low-voltage special-system cabling installed in applicable walls and ceilings, certain cabling installed in existing raceways installed by others, direct-burial low-voltage special-system cabling, overhead low-voltage cabling to structures, terminations and splicing of low-voltage special-system conductors, and associated excavation and trenching within the classification scope.

The ES-3 classification does not authorize general interior or exterior wiring of circuits operating above 50 volts. Work outside the authorized ES-3 scope requires the appropriate New Mexico electrical classification.

After the Qualifying Party has completed the applicable requirements, the business entity must submit the company license application and required documentation. New Mexico's contractor licensing process includes applicable bond, tax registration, and company documentation requirements. Workers' compensation coverage is also required for licensed entities.
