NAEC Certified Accessibility & Private Residence Lift Technician (CAT) Exam — Summarized Coverage
The NAEC CAT (Certified Accessibility & Private Residence Lift Technician) Exam assesses competency
in the installation, maintenance, inspection, troubleshooting, and safety compliance of accessibility
lifting equipment such as stairlifts, vertical platform lifts, inclined lifts, and private residential
elevators. It is grounded in ASME, NEC, ADA, OSHA safety standards, and accessibility lift technology
principles.
1. NAEC CAT certification structure, eligibility, and apprenticeship/work-hour requirements
2. OSHA safety regulations for elevator and lift installation and service work
3. General electrical safety principles and shock protection practices
4. National Electrical Code (NEC) concepts related to lift wiring and circuits
5. ASME A17.1 elevator safety code fundamentals
6. ASME A18.1 safety standards for platform lifts and stairway chairlifts
7. ADA accessibility requirements and compliance principles
8. Types of accessibility equipment: stairlifts, vertical platform lifts, inclined lifts
9. Private residence elevator systems: design, operation, and components
10. Mechanical principles: pulleys, gears, rails, drive systems, and counterweights
11. Electrical control systems: relays, switches, sensors, and control panels
12. Hydraulic lift systems: pumps, cylinders, fluid mechanics, and pressure systems
13. Traction lift systems and cable-driven mechanisms
14. Safety devices: interlocks, brakes, limit switches, and emergency stops
15. Installation procedures for residential and accessibility lift systems
16. Blueprint reading and layout interpretation for lift installations
17. Load capacity, balancing, and weight distribution principles
18. Preventive maintenance schedules and inspection routines
19. Troubleshooting mechanical failures (noise, vibration, misalignment)
20. Troubleshooting electrical faults (open circuits, shorts, control failure)
21. Diagnostic testing tools (multimeters, test lamps, pressure gauges)
22. Lift commissioning and functional testing procedures
23. Emergency rescue procedures and manual lowering systems
24. Fire safety integration and building code coordination
25. Battery backup systems and emergency power operation
26. Ride quality, leveling accuracy, and performance testing standards
27. Structural requirements for lift shafts, rails, and support systems
28. Fasteners, anchoring systems, and load-bearing safety principles
29. Documentation, inspection reporting, and compliance verification
30. Real-world scenario decision-making involving installation faults, safety hazards, code
compliance, and system repair strategies

NAEC CAT Exam — MCQ Practice Batch 1 (Questions 1–50)
1. Which standard primarily governs safety requirements for platform lifts and stairway chairlifts?
A. NEC Article 430
B. ASME A18.1
C. OSHA 1926
D. ADA Title III
Answer: B
Rationale: ASME A18.1 specifically covers safety requirements for platform lifts and stairway chairlifts in
detail.
2. What is the primary purpose of interlocks in accessibility lift systems?
A. Increase motor speed
B. Prevent unsafe door or gate operation
C. Reduce electrical resistance
D. Improve ride comfort
, Page 3 of 145
Answer: B
Rationale: Interlocks ensure lift doors or gates cannot open unless safe operating conditions are met.
3. According to OSHA, what is the most critical rule before servicing electrical lift components?
A. Increase voltage supply
B. Lockout/tagout procedures must be applied
C. Disable all alarms permanently
D. Remove grounding wires temporarily
Answer: B
Rationale: Lockout/tagout ensures equipment cannot be accidentally energized during maintenance.
4. Which component is responsible for converting electrical energy into mechanical motion in lifts?
A. Relay switch
B. Motor
, Page 4 of 145
C. Limit switch
D. Control transformer
Answer: B
Rationale: The motor converts electrical energy into mechanical motion to move the lift system.
5. What is the main function of a limit switch in a residential elevator system?
A. Increase hydraulic pressure
B. Control lighting inside cabin
C. Stop movement at travel boundaries
D. Adjust cable tension automatically
Answer: C
Rationale: Limit switches prevent the lift from moving beyond its safe upper or lower travel limits.
