Nec
The arc fault detector circuit breakers are required by NEC code. If your house was built under the version of the code requiring that type of breaker (or later) you must replace with the arc fault breaker. If you use the 'regular' type and something happens to your house as a result of that breaker, your insurer may decline to cover you.
