Cindy,
while anyone will agree safety is the key, there are a few issues surrounding this goal.
First is the stat's used to market , as well as the stat's that are going to be collected pertinent to any efficy or validation.
Second would be the simple economics, as the arc-fault sells for $35-$40. This has proven to double the cost of a service upgrade in Vermont, and may very well do so nationally if usage were to grow in the NEC as GFI's did. Customers here have questioned this asking why not simply have an ARC-fault main breaker, which in turn has had some inquiries as to european systems...
