You can test and see if they are TR. If you can plug something into them they are not TR.
No truer words have ever been spoken!
OMG do I hate TR receptacles. I have only come across one that did not take brute strength to plug something into, or even more strength to unplug!
That was a brown receptacle that I put in my garage. All the switches and receptacles are brown in my garage via the previous owner. Trying to find brown stuff was hard enough, as most places around me don't sell the brown stuff.
But I ordered a few online and I figured they would be just as hard to use as all the other ones I have come across. Nope. They work as if there is none of that plastic **** inside of them.
And these are Leviton brand receptacles. They appear to be no different than any of the other colors, like white, black, or whatever. And they were the same price as the other colors too. They just work better.
