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".
