Re: AFCI Protection

The code states that 15, 20 amp outlets should be protected. Smokes draw low current, so do you think arc fault protection is even necessary?

Re: AFCI Protection

Whether or not it is necessary is irrelevant. It must be done. Some would argue the necessity of having any afci protection. Also, if a switch is controlling an outlet that is not in the bedroom, such as a dead end threeway controlling floodlights fed from a circuit elsewhere in the house, the switch need not be afci protected.

Re: AFCI Protection

This as edgy as it gets !!!!
96 code - receptacle outlets to be afci protected
02 code outlets to be afci protected
Both in dealing with bedrooms.100 gives us the definition of an outlet which leads to more rebutal is a switch a point that derives power.
In MHO yes without that switch the light receptacle fan blah blah blah can`t be ustilized from that room with out utilizing it IE; hitting a switch ;)
When 02 cycle was adopted here we were informed by letter and a meeting that from the day of adoption of the 02 code all receptacle outlets,switches in a bedroom WILL be afci protected,changing to outlet leads to 100 and there fore a switch is a point that is used to utilize power.
I thought the whole thing stupid but all I am is a dumb sparky 1st a receptacle outlet now a receptacle,switch,smoke detector anything used in that room called a bedroom shall be afci protected.The question came up about closets in a bed room and we were told if the closet is in the same room as the bedroom afci.Now if you can access that closet from another door technically it is not in the bedroom since the lights can be turned on from a non afci room.but if there is a switch 3 way in this case afci it :confused:

Re: AFCI Protection

a typo meant 99 cycle.Thyese guys do march to an entirely different drum !!!!! Try this on for size.prior to 1/1/05 the ufer was a 20 ft piece of rebar that was bent outwards from the slab and pointed up some were left 2 maybe 3 ft beyond the slab.
On rough in we were required to attach our #4 to it and cut below grade but left open since on permit board uffer and rough were signed off together,building inspector signed that ufer was installed before concrete was poured.
Now here comes final all pretty and sodded,landscaped,mulched.DIG THAT SAME SIGNED OFF UFFER TO BE INSPECTED AGAIN !!!! ;)

Re: AFCI Protection

I don't have 99 code handy, does it require that only 15/20A convenience receptacles be AFCI protected? I understand in the 2002 code it states 15/20A outlets, which means any point at which current is taken to supply utilization equipment, so I would have to agree with the thread comments.

Appreciate the input.

The entire circuit that feeds any bedroom outlet must be AFCI protected. If you put the bedroom lights, the bedroom receptacles, and the bedroom smoke detectors on three different circuits (just an example!), then all three circuits must have AFCI protection.

Think of it this way: Nothing in the code prohibits you from putting a bedroom receptacle and a hallway receptacle on the same circuit. A hallway receptacle does not "require" AFCI protection, but in this case it will get it. That is because it shares a circuit with a bedroom outlet, and the entire circuti feeding that bedroom outlet must have AFCI.

Re: AFCI Protection

David, the 99 NEC required all "Receptacle Outlets" in bedrooms to be AFCI protected starting on (jobs permitted on or after) Jan 1 2002 even if you stayed under the 99 NEC. On this same date, if you addopted the 2002 you would have to protect all "Outlets" due to the wording change.

Take note, by definition a "Switch" serving an outlet outside of the bedroom which would be fed from another circuit, i.e. exterior lighting, would not need to be protected even under the 2002.

Re: AFCI Protection

Was the AFCI an idea to prevent fires? If so where's the wisdom in putting smoke detectors on them? Fire Marshal;"Good news,the afci tripped when the insulation burned off, bad news,SD's
were on the circuit so nobody woke up."

Maybe the breaker was tripped because it was preventing an electrical fire :eek:

Ryan,fire unrelated to afci circuit.Afci tripped after fire started, but before SD's went off; again, no one woke up.
