The code says: "IN DWELLING UNITS"
So does this mean outside receptacles do not need TR ?

406.12 Tamper-Resistant Receptacles in Dwelling
Units. In all areas specified in 210.52, all nonlocking-:
type 125-volt, 15- and 20-ampere receptacles shall be
listed tamper-resistant receptacles.

210.52(E) references outdoor receptacle outlets so, yes, tr is required for those recs in those areas. Note that 406.12(a) says "in all areas" specified in 210.52- per the 2014.

No it doesn't. The word "In" does not appear in the title of that article. What you have is 406.12 telling us that any receptacle that was addressed in 210.52 has to be TR. That would include the outdoor outlets addressed in 210.52(E).

Well not so fast. In my book the heading in bold says " Tamper-Resistant Receptacles in Dwelling Units.
Does not say "for" it says "in" and one could argue that though 210.52 (E) may specify a outside receptacle it is not "IN" a dwelling unit.

In NEC 2014, 406.12 says "Tamper-Resistant Receptacles"
In NEC 2011, 406.12 says "Tamper-Resistant Receptacles FOR Dwelling Units"

You'd have to go back to NEC 2008, where 406.11 (not 406.12) says "Tamper-Resistant Receptacles IN Dwelling Units"

Good argument. The 08 NEC has the section you describe, tho you must be using the 11 as the 08 section is 406.11. Regardless the title, the opening words of 406.11/.12 are "In all areas specified in 210.52.." (2008 NEC).

Besides, outside receptacles that are part of the building could be considered 'in the dwelling unit'. It does not say "inside the dwelling unit". ;)

Perhaps tho you'd elaborate on why this is an issue. TRs are required in so many places in (or inside) a dwelling that it's easier to stock and install only TR than try to remember the incredibly few exceptions to installing them

Can you send us a scan of that? My 2011 code book has the word "in"

(I didn't want to type "says" because we are so anal here, that could cause a whole new semantic argument!:lol::lol::lol:

I'm looking at it online at NFPA.org.

That should not have come out that way as that was a change made in the ROP and shows up in the draft version with the word "for".
406.12 Tamper-Resistant Receptacles for Dwelling Units. In all areas specified in 210.52, all nonlocking type 125-volt, 15- and 20-ampere receptacles shall be listed
tamper-resistant receptacles. [ROP 18-62, 18-68]

The following is the proposal that made that change and the reason was as suggested here. The title did not reflect the intended requirement of the rule. red text = delete, blue text = new
18-68 Log #2786 NEC-P18 Final Action: Accept
(406.11)
_______________________________________________________________
Submitter: James W. Carpenter, International Association of Electrical
Inspectors
Recommendation: Revise the title of 406.11 as shown:
406.11 Tamper-Resistant in for Dwelling Units. Substantiation: The title is proposed to be revised to reflect the fact that the actual requirement applies to receptacles that are not only “in” the dwelling unit, but other locations as well (such as outside, etc.).
