The objective of this paper is to increase inspector awareness of arc-fault circuit interrupters (AFCI).
The arc-fault circuit interrupter (AFCI) is emerging as a new device in the National Electrical Code and in residential installations to enhance electrical safety.
The proper application of overcurrent protection rules for air-conditioning and refrigeration equipment can be made relatively easy by following a few basic steps.
Although no single technology will protect against all electrical ignition scenarios, arc-fault detection was identified as an effective means of reducing fires
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.
UL has five new categories specifically for AFCI devices, now covered under UL 1699, Standard for Arc-Fault Circuit Interrupters.
The electrical inspector’s voice and input into the affairs of the industry is vital.
What should happen when the electrical utility or a utility customer decides to convert the ungrounded 600 volt, 3-wire supply to a 600/347 volt, 4-wire, solidly grounded electrical supply?
When we talk about minimum ground clearances of span conductors, we have to know the sag of the conductor because the minimum height of attachment on a structure to comply with the NESC
Guidance was provided to the 20 Code-Making Panels on several issues that are to be addressed during the 2002 NEC cycle.
