The big orange box has TR-GFCIs for about $3 more than the non-TRs.($15.49 vs $12.59).

The samples of the TRs all had the "TR" features broken, 1 shutter was open. As to how many of the TRs will break in the field .. only time will tell.

California is still on the 2007 CEC, derived from the 2005 NEC and I pray they get the bugs worked out of the TRs before we adopt the 2008 NEC.
