Hello,
If you have not registered then do so by clicking on N.E.C. code book on right side bar. If no sidebar is present then look below, tap to log-in an be redirected to register. Then just follow instructions. Please do not use the maintenance tips above to register. If you have already registered go ahead and sign in below. Ask your question and if you experience any problems during the process use the maintenance tips button above to send me a quick note about it, use the comments section at bottom of that window. The maintenance tips is also used for anyone interested in registering to receive future emails about yearly maintenance tips, not for registering to ask questions. To register click on the NEC code book picture on right hand sidebar of my main website page.
While we are conversing here today and to get to a solution quicker please have your wiring project up and going. Getting a question answered usually takes some time doing some visual checking on your part and then replying back to me. So be near your wiring project while we are getting things straight. And if you have accidentally selected the wrong category look to the side bar on main page on right and select another category. If your task at hand is not listed on the sidebar go >here< and ask your question in the non-categorized question section.
The big question is do I use arc-fault-circuit-interrupterย or ground-fault-circuit-interrupter or both?
I recommend using tamper-resistant because basements are places where the unusual happens. It never fails where someone is messing around with something and something breaks or someone gets shocked. At some point along the way a shock will happen. The chances of changes occurring in homes with basements has risen tremendously because of the awareness of this important functionality to the public. Also because of the high use of low voltage systems grounding has become a much larger issue. Most grounding issues can be taken care of with less extensive amount of work in a house. But a commercial building could get very expensive. So know what your grounding system is doing.
The factories are busy playing with the many combinations needed to satisfy the N.E.C. The electrical supply houses are the best source to get what you need.
Helpful Identifier stamps: TR (tamper-resistant), WR (weather-resistant) will be stamped on the outlet itself. AFCI receptacles do not have these identifiers as of today. I recommend using GFCI outlets w/TR and WR and using AFCI breakers to protect entire circuit.
N.E.C. requires GFCI and AFCI in some instances now. I recommend using both in basements.
