I am going to make a prediction that injuries will increase with the use of TR receptacles. The kids will just try harder and instead of just poking 1 wire they will have to get 2 at least. Just imagine the result of a kid with 2 metal object, 1 in each hand and they get them both in at the same moment. Current accross the chest. I for 1 am a kid that poked things into sockets. I became an electrician. I guess i enjoyed the experience. This rule change has been proposed for the Canadian Electrical code.
