Requirements for Specific Equipment

DOE-HDBK-1092-98

6.0 REQUIREMENTS FOR SPECIFIC EQUIPMENT

The electrical safety requirements for specific equipment are determined by the following standards:

1. NFPA 70, National Electrical Code (NEC)

2. 29 CFR 1910, Occupational Safety and Health Standards

3. 29 CFR 1926, Safety and Health Regulations for Construction.

4. NFPA 70E, Standard for Electrical Safety Requirements for Employee Workplaces.

29 CFR 1910 and 1926 frequently reference other safety guidelines for design, operation, and

maintenance. Such other guidelines comprise ANSI, ASTM and IEEE specifications and information

derived from various engineering sources or equipment manufacturer association standards.

However, the key document is NFPA 70, the NEC; all the other documents are keyed to it. The NEC

reflects wiring and installation requirements that provide for a safe electrical system.

6.1 CONVEYING SYSTEMS

Conveying systems are used to move materials, goods, etc., from one place to another. Because of

their conditions of use, they are usually classified in service applications as intermittent duty per NEC

Tables 430-22(a) and 620-15.

6.1.1 GENERAL DESIGN, INSTALLATION, MAINTENANCE, AND

INSPECTION REQUIREMENTS

The general design criteria for elevators, dumbwaiters, wheelchair lifts, escalators, and cranes

should comply with:

1. ASME/ANSI A17.1, Safety Code for Elevators and Escalators

2. NFPA 70, National Electrical Code

3. ANSI C-2, National Electrical Safety Code (NESC)

4. Uniform Building Code, Chapter 51 (except enclosures)

5. 29 CFR 1910, Occupational Safety and

Health Standards

6. 29 CFR 1926, Safety and Health Regulations for Construction

7. Uniform Federal Accessibility Standard (UFAS), Handicapped Wheelchair Lifts
