New 2002 NEC requirements that may save lives someday!


440.65 Leakage Current Detection and Interruption (LCDI) and Arc Fault Circuit Interrupter (AFCI).

Single-phase cord-and-plug-connected room air conditioners shall be provided with factory-installed LCDI or AFCI protection.

The LCDI or AFCI protection shall be an integral part of the attachment plug or be located in the power supply cord within 300 mm (12 in.) of the attachment plug.


550.25 Arc-Fault Circuit-Interrupter Protection.

(A) Definition. Arc-fault circuit interrupters are defined in 210.12(A).

Obviously there have been enough AC related incidents.

So comes the Q, if the amazing life saving technology of AFCI's and GFCI's are indeed what they claim, why do we not provide for whole house protection similar to systems overseas?

The code has slowly stipulated an increased level of protection to the point where safety could be economicially adressed better.

Sparky,

Would you really want to shut down a whole House? I don't think that would be good at all, do you?

We get asked this question at inspector meetings. The issue is one of ease of troubleshooting, isolating the cause, and not cutting off power to the whole home. If electricians had to try to find the fault by tracing each circuit, the technology would never be installed.
