Requirments for Specific Equipment

DOE-HDBK-1092-2004

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 2002)

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 in the Workplace

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 an installation

that is essentially free from hazard but not necessarily efficient convenient or adequate for good

service..

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.

6.1.1

ELECTRICAL DESIGN CRITERIA

Electrical design criteria should be closely coordinated with the architect, structural engineer,

fire protection engineer, mechanical engineer, and electrical safety engineer to ensure that all

discipline requirements are coordinated and met.

Factory and field performance tests and control and wiring diagrams should be specified in the

purchase order or contract because they are not otherwise provided by the factory. Acceptance

tests conducted by the factory representative, qualified independent inspector, or engineer are

recommended. Tests conducted by UL and Factory Mutual Engineering Corporation (FM) are

also acceptable.

ANSI and CMAA standards should be carefully reviewed to ensure that all applicable safety

requirements are covered in the specifications.

The designer should specify the following requirements:

1. Available system voltage

2. Control voltage

3. The motor is constructed for the specific application
