Hey Roger,

The NAHB document is a 480K .pdf file that, at least as far as my computer experiences it, is set up to download completely before Adobe Reader displays it.

On my 256K DSL connection this takes about a third of a minute. An alternative route would be using the homepage at www.nahb.org and use the Search box in the upper right corner and type in "arc fault". The return will include "Why We Have A Problem With It".

It loads fine now.

The gist is that they built a test setup where they made arcs, made loose connections, and simulated other faults, and the three ACFIs they tested, from two manufacturers, never tripped--not even once.

has anyone had problems with nuisance tripping of these (afci) we have had 2 callbacks each callback referenced 3 breakers each. the HO installed childproof/tamperproof receptacle plugs (all plastic) every breaker we installed tripped after the covers were plugged in. this concerns me as it must mean that there is current there.

Vt was subjected to AFCI's in the 99' cycle

we had virtually no info, although many of us wrote UL , or sought spec's through whatever channels we could

nobody gave up anything, all answers were tempered vagarities, even the rep B.F. that posted here did not forward pertinent info

until 210.12 became a national code in the '02

the Marchand & Dini finally forwarded specifics in the Jan/Feb NEC digest....

'the Truth about AFCI's, pt 1 & 2'

they knew they were in at this point, how often does the code backpeddal right?

add to it, that the majority of 02' proposals were roundfiled with the rationale of a 6 yr old....

for those of us that have followed this it was as our own trades enron, we've fallen from grace.

it's just that simple

will do Al

on a similar matter, Vt has required all single family homes to have ALL ;living area' circuitry via AFCI

at first i was stuffing 30-40 afci's in a panel here, try it and you'll realize what a piece of overpriced crap they are, adds $600 to a bid, and creates a world of callbacks....

the reps are ZERO help, belive me

the thing is, VT does not inspect single family homes, and i found i was the only EC around being the good dubie

i meet the national code only now, and i see many a new home without an afci at all

so sue me
