This is the second part of a summary of proposed changes for the 2002 National Electrical Code® acted on by NEC Code Making Panels in January 2000.
Guidance was provided to the 20 Code-Making Panels on several issues that are to be addressed during the 2002 NEC cycle.
Recently, there has been a significant increase in questions from inspectors about CE Marking and its acceptability as a method of conformity assessment in North America.
The 1999 NEC contains rules for low-voltage and limited-energy systems of all types ranging from telecommunications/LAN to fire alarm to closed-circuit TV systems used for security purposes.
The new Section 210-12 of the 1999 National Electrical Code (NEC) requires arc-fault circuit-interrupter protection for some branch circuits. Does UL List such devices?
Can a UL Listed product be modified in the field if the manufacturer indicates that the revision is ok and sends out new parts?
The National Electrical Safety Code® (NESC®) occasionally references other standards, such as ANSI Z535.1-1991, when it comes to safety signs, labels, and tags.
