The New Mexico ES-10 Water Well Pump Installer examination contains 50 questions. Candidates must earn a score of 75%, equal to 38 points, and are allowed 120 minutes to complete the examination.
The official examination content outline divides the ES-10 test into the following subject areas:
General electrical installation requirements and grounding and bonding are two of the largest portions of the test. Motors, pumps, and controls are also a major subject because the ES-10 classification centers on electrically powered water well pumping systems.
Candidates should also prepare for questions involving feeders, branch circuits, conductor selection, raceways, boxes, panelboards, overcurrent protection, and qualifying solar photovoltaic systems. The examination may include questions based on both reference materials and general trade knowledge.
A silent, non-printing, non-programmable calculator is permitted in the examination center.
The New Mexico ES-10 Water Well Pump Installer examination is an open-book test. Candidates are responsible for bringing permitted reference materials to the examination center.
Approved examination references must be bound. They may be highlighted, underlined, or indexed before the examination. Permanent tabs may be used for indexing, but temporary tabs such as Post-it notes are not allowed. Additional loose or attached papers are prohibited.
Reference books containing writing are not permitted in the examination center, and candidates may not write in the references during the examination. These rules make advance organization and book familiarity especially important.
Open-book testing does not eliminate the need to study. With 50 questions and 120 minutes available, candidates benefit from recognizing the subject of a question quickly and knowing which code article, table, chapter, or reference is likely to contain the answer. Effective preparation should combine electrical knowledge with repeated practice locating information.
The ES-10 examination is part of the New Mexico contractor licensing process. A contracting business seeking this classification must have a qualifying party who satisfies the applicable experience and examination requirements.
Application Service is included with this Ultimate package to provide additional support with the licensing application process while candidates work through their examination preparation.
New Mexico identifies ES-10 as the Water Well Pump Installer specialty classification. The classification requires two years of qualifying experience.
The authorized scope covers residential and commercial water well pumps rated at 600 volts or less, single phase or three phase. Contractors working under this classification may install, maintain, repair, or replace electrical equipment, wiring, and accessories used in connection with qualifying water well pump systems.
Variable frequency drives are included within the scope. ES-10 also authorizes subpanels, luminaires, and receptacle outlets located within a well pit or well enclosure. Branch-circuit and feeder conductors may be installed from service equipment or a panelboard to the water well pump location.
Incidental excavation and trenching are included when associated with authorized ES-10 work. Solar photovoltaic arrays rated at 5 kW or less are also included when dedicated to pumping equipment.
The classification does not include electrical systems over 600 volts, electrical services, general building wiring, or unrelated electrical wiring. Contractors should remain within the work authorized by their license classification.
The official ES-10 examination reference list identifies the following materials as allowed in the examination center:
The official ES-10 examination list specifies the 2007 edition of the National Electrical Safety Code for exam-room use. The rental package listed above includes the 2017 edition as part of the study materials.
Candidates should use the specified code editions for code-based examination questions. Books carried into the testing center must comply with the examination rules governing binding, highlighting, underlining, indexing, tabs, writing, and loose materials.
ES-10 preparation should begin with general electrical installation knowledge. Candidates should review fundamental installation requirements, electrical terminology, working clearances, equipment requirements, environmental conditions, and the general rules that provide a foundation for electrical work.
Grounding and bonding account for eight examination questions, making this one of the largest categories. Study grounding electrodes, equipment grounding conductors, bonding requirements, metal enclosures, conductive parts, and other grounding and bonding provisions applicable to pump installations.
Motors, pumps, and controls account for six questions. Candidates should review motor circuits, controllers, disconnecting means, overload protection, overcurrent protection, motor conductors, pump controls, and variable frequency drives. Knowing how to navigate motor-related NEC provisions and tables can be especially useful.
Conductors and cables account for five questions. Preparation should include conductor ampacity, insulation types, installation conditions, conductor sizing concepts, and requirements that can apply to feeder and branch-circuit conductors serving water well equipment.
Raceways and boxes also account for five questions. Candidates should review raceway selection, installation, support, fittings, boxes, wet or outdoor locations, underground installations, and other requirements associated with protecting and routing electrical conductors.
Panelboards and switchboards make up another five questions. Study panelboard requirements, circuit arrangements, overcurrent devices, equipment installation, and related electrical provisions that may affect water well pump systems.
Feeders and branch circuits account for four questions. Because ES-10 specifically authorizes branch-circuit or feeder conductors from service equipment or a panelboard to a well pump location, candidates should understand the electrical rules governing these circuits.
Solar PV systems account for three questions. The ES-10 license scope includes solar photovoltaic arrays rated at 5 kW or less when dedicated to pumping equipment, making photovoltaic knowledge a relevant part of preparation.
The New Mexico Electrical Code accounts for three examination questions. Candidates should study state-specific electrical provisions in addition to the NEC rather than relying only on national code material.
A practical study method is to identify the subject first, select the likely reference second, and then locate the governing provision. Repeating this process during practice questions can strengthen code-navigation speed while reinforcing technical understanding.
1 Exam Prep helps candidates organize preparation for the New Mexico ES-10 Water Well Pump Installer examination around the code references, electrical subjects, and study habits needed for an open-book specialty contractor test.
Trade-focused review helps students work through grounding and bonding, feeders, branch circuits, conductors, cables, raceways, boxes, panelboards, overcurrent protection, motors, pumps, controls, photovoltaic systems, and New Mexico electrical requirements. Instead of attempting to read every page of every code book from beginning to end, candidates can build a study routine around the subjects identified in the official examination outline.
Practice-oriented preparation also emphasizes reference navigation. Candidates can repeatedly identify the likely code source, locate applicable provisions, and apply those requirements to exam-style situations. This type of practice can help improve familiarity with articles, tables, definitions, exceptions, and cross-references.
Some book(s) are highlighted and tabbed for exam preparation. These organizational tools can make important areas easier to locate while candidates develop their own familiarity with the references.
The Ultimate package includes 1 year of course access, allowing candidates to establish a study schedule, revisit difficult electrical subjects, and continue practicing code navigation over time. Application Service is also included to support the licensing process while candidates concentrate on examination preparation.
The goal is to create a more structured path through technical study, reference navigation, practice, and contractor licensing preparation. Consistent study and familiarity with the permitted references can help candidates approach the ES-10 examination with stronger preparation and greater confidence.
