I am not a fan of the TR receptacles. However having declared that, I will admit that the new lines of TRs are user friendly. They even include GFI and combination devices. No more insert/turn and then push in the rest of the way. Resistance to putting in a plug is almost the same as a regular device. They are designed to provent anything going into only one opening of the device. The biggest problem I see with how 406.11 is written is that it applies to all receptacles in the AREAs listed in 210.52. That means the receptacle in the cupboard behind the microwave has to be tamper-resistant. It is going to be hard to explain to the customer the extra (minimum)cost for that recptacle. 210.52 excludes receptacles in cupboards / luminaires & appliances and those over 5 1/2 feet above the floor. 406.11 as written does not include those exceptions. I feel that the exceptions need to be included in 406.11 to put some logic into the arguement for using the TRs. Switched receptacles are also excluded in 210.52 but, because they may be accessable to the inquisitive little darlings they should be included in the TR requirement. As an inspector I hate being an enforcer for greedy merchants.
