It has been a while since the technical data on AFCIs has been summarized.

In warming up to the 2005 NEC proposal deadline in October 2002, this Forum pulled together a lot of data, but surprisingly little technical data for specific models of AFCIs currently being manufactured for sale and installation.

What information has been released in the last two years?

First, I want to apologize for loosing it with Joe and causing the removal of the previous thread.

I do not know where to get technical data on the individual AFCIs. I do know that the only basic advantage that an AFCI has over a standard circuit breaker is the "GFI" portion of the circuitry. The GFI portion is set at 30 to 50 mA depending on the manufacturer and it will not start to react to anything until the load current exceeds 75 amperes. UL has the testing requirements that all the standard AFCIs must meet. The circuitry is different for each manufacturer. If you are looking for something from the individual manufacturers, I doubt it will be available.

I don't think any new information has been made available in the last couple of years. I really expect to see a lot of information about the combination type as time passes.

Charlie,

You did not cause removal of anything. It was one of those threads that was going down the wrong road from early on.

No Worries, CharlieE.

The absense of new technical information concerns me.

I have a 3" binder on the shelf here that is full of what I could glean about AFCIs from the collective wisdom and knowledge of the Forum contributors and other parties. I haven't had anything to add to the folder since December, 2002.

ElectricAL:

Here is a link to some AFCI information on the UL site:
http://www.ul.com/regulators/afci/

I was unable to find any dates later than January 2002.

I will search for more.

Was there anything in the NFPA transcript for the adoption of the 2005 NEC?

Charlie

I see where the meeting ended at 8 PM, that was a long day.

UL 1699 http://ulstandardsinfonet.ul.com/scopes/1699.html

1 Scope

1.1 The requirements of this Standard cover arc-fault circuit-interrupters (AFCIs) of the branch/feeder, outlet circuit, portable, and cord type intended for use in dwelling units. These devices are intended to mitigate the effects of arcing faults that may pose a risk of fire ignition under certain conditions if the arcing persists.

1.1.1 The requirements of this Standard also cover Leakage-Current Detector-Interrupters (LCDIs), which are not prohibited from being provided with cord sets or power-supply cords. These devices are intended to sense leakage currents flowing between or from the conductors of a cord set and interrupt the circuit at a predetermined level of leakage current.


1.1.1 added effective July 15, 2004
1.2 These devices have a maximum rating of 20 A and are intended for use in 120-V ac, 60-HZ circuits.

1.3 These devices are not intended to detect glowing connections.

1.4 In these requirements the term device is used generically to apply to all of the devices covered by these requirements and is modified when the requirement does not apply to all types.

1.5 An AFCI that is also intended to perform other functions, such as overcurrent protection, ground-fault circuit-interruption, surge suppression, any other similar functions, or any combination thereof, shall comply additionally with the requirements of the applicable Standard or Standards that cover devices that provide those functions.

1.6 Deleted and Relocated to Foreword July 15, 2002


1.6 revised July 15, 2002

Hello Al,
 Quote:

At that price I'll bet you'll be purchasing a few for gifts.

I couldn't get your link "The Arc Fault Circuit Interrupter - Why We Have a Problem With It" to open but I've been having other internet or dial up problems too.

Roger
