Receptacles for Maintenance Personnel - NFPA 79 16.1.2

Does anyone know the reason this was added?

I consider a "Grace Programming Port" to be an included under this article but some of my fellow controls design people think not. Can anyone offer any arguments either way?

16.1.2 Receptacles.
Worker safety is enhanced through a new requirement that applies to maintenance receptacles.

"16.1.2 Receptacles, which are part of the industrial machine, either external or internal to the control cabinet and intended for use by maintenance personnel, shall have ground-fault circuit-interrupter protection for personnel."

In addition, Section 16.1.2 requires that work lights be protected by Class A type ground-fault circuit interrupter if used in wet locations.

reasoning for change

NFPA 79, the Electrical Standard for Industrial Machinery 2002 edition, is scheduled to be published in October 2002. During this past cycle, NFPA 79 has undergone a major overhaul in an effort to harmonize requirements with those of IEC 60204. This, as you can imagine, was a major undertaking and resulted in a heavy workload. The work pioneered by the NFPA 79 technical committee has provided a benchmark for future harmonization efforts. This article will discuss the harmonization process that took place and resulting changes to the NFPA 79 standard. In addition, significant changes that occurred during the 2002 cycle will be discussed individually.
