Be sure to give your reasons why.

210.12 Arc-Fault Circuit-Interrupter Protection.

(A) Definition: Arc-Fault Circuit Interrupter (AFCI).

An arc-fault circuit interrupter is a device intended to provide

protection from the effects of arc faults by recognizing

characteristics unique to arcing and by functioning to deenergize

the circuit when an arc fault is detected. [ROP


(B) Dwelling Units. All 120-volt, single phase, 15- and

20-ampere branch circuits installed in dwelling units shall

be protected by a listed arc-fault circuit interrupter, combination

type installed to provide protection of the branch

circuit. [ROP 2–105, 2–142, 2–111]

FPN No. 1: For information on types of arc-fault circuit

interrupters, see UL 1699-1999, Standard for Arc-Fault

Circuit Interrupters.

FPN No. 2: See 11.6.3(5) of NFPA 72®-2007, National

Fire Alarm Code® for information related to secondary

power supply requirements for smoke alarms installed in

dwelling units. [ROP 2–118a]

FPN No. 3: See 760.41 and 760.121 for power supply

requirements for fire alarm systems. [ROP 2–143]

Exception: The location of the arc-fault circuit interrupter

shall be permitted to be at other than the origination of the

branch circuit where the arc-fault circuit interrupter is installed

within 1.8 m (6 ft) of the branch circuit overcurrent

device as measured along the branch circuit conductors.

[ROP 2–147, 2–137]

Yes, because I am totally in favor of saving lives, and this is one way for me to get that message accross to the people who want to install electrical systems!

Many are unqualified as well, and the DIY industry needs people who understand the hazards involved!
