I link to this site in my sidebar, so if you ever have need of electrical information, tips, or manuals (or more), I really recommend this site. Wayne is a friend as well as a meticulous expert in electric. I constantly refer to his site when I am doing electric. I love his articles. I saw one the other day and it’s important enough to warrant an honorable mention, because it’s a new development in the National Electric Code that will affect electric installations (and costs). It’s ezdiyelectricity.com the official introduction of AFCI circuit breakers.
Probably the most important change in the 2008 National Electrical Code® (NEC®)is that Arc-Fault Circuit Interruption (AFCI) Protection is now required for all 120-volt, single phase, 15- and 20 ampere branch circuits installed in most areas of your home. The requirements which applied only to bedrooms in 2005 have been extended to every habitable area of the house in 2008.
Arc-fault circuit interrupter protection is required in family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sun rooms, recreation rooms, closets, hallways or similar rooms or areas.
AFCIs will not be required in bathrooms, kitchens, laundry rooms, unfinished basements, garages, attics or outdoors.
There’s also information about tamper-resistant receptacles, something I need to read more about.
I don’t think my town has officially accepted the 2008 NEC yet. I believe they still go by the 2005. So every town is different– be sure to check with your codes department.
