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?
