I have not seen any TR two wire receptacles, and none are in the P&S literature I have.

I have to ask....why TR?? Is that a CEC thing?

Oh the Inspector has stated on a corr. notice that recept.s be two-wire of TR type, for all replaced knob and tube outlets. The Homeowner bought the place with the plugs already replaced, I guess it passed the selling inspection 13 years ago when he bought it. He's now trying to make the service safer instead of being in a cabinet at grade with the gas meter, opened a can of worms

I think a GFCI breaker would allow replacement with the TR 5-15s.
406.3(D)(3)(c) in 2008 406.3(D)(2)(c) in 2011

Quote
(c) A non–grounding-type receptacle(s) shall be permitted to be replaced with a grounding-type receptacle(s) where supplied through a ground-fault circuit interrupter. Grounding-type receptacles supplied through the ground-fault circuit interrupter shall be marked “GFCI Protected” and “No Equipment Ground.” An equipment grounding conductor shall not be connected between the grounding-type receptacles.



The requirement for AFCI would be a local call. A breaker incorporating both should work

The 2011 code requires this effective 1/1/14
406.3(D)(4)

thanks greg, I do believe he was stating the 2008 code for TR recept.s but also didnt write a correction but said all convenience receptacles should be afci protected. but that was for new circuits, and all I've run are circuits to refeed the old fuse panel,

AFCI on old work seems to be all over the place depending on how your "rehab/existing building" codes are written and what your AHJ wants. I usually avoid trying to guess what the local guys want. If the 2011 is adopted and they leave 406.3 intact a lot of that indecision will go away. You will be doing AFCI and GFCI on any replacements after 1/1/14 the way I read it.
