I replaced the cheap junk self contained outlets with real residential outlets in a box. The idea that electricians and inspectors are part of the process is not the reality in the RV business.
I have searched and searched and can not find any U.S.A. made duplex.
I did find a couple of good made in USA used at a thrift store.
May someday we can find new ones made in the USA.
That could be true at the retail/residential level. I would try an electrical wholesaler - where the contractors buy "the good stuff". I've often avoided retail electrical items as sometimes you get what you pay for. Some receptacles are made in the US like in the photo. I have never heard of Trademaster - sounds like a name the Chinese would use (like Chicago Electric, eg., lol). For US made recepts. I would look for Hubbell, Cooper, P&S, etc. which probably means going to "spec. grade."
THE most important thing to know is that any device that carries a UL or CSA marking has gone through a long, detailed and rigorous set of tests in order to become certified and legally able to carry the designation and as a result ensures a level of safety to the public. As Mex mentioned, there are a number of grades of receptacles and have the lowest to higher retention force, larger contact surface area and best (lowest) contact resistance with the best being hospital grade. Being US made doesn't necessarily mean better quality in the case or recepts. Recepts. and other wiring devices MUST be UL or CSA certified to be sold & used in the US and Canada.
Please note that I never mentioned "made is USA" as it is getting to be impossible to buy anything but imported. This thread went from using the type of wire connection to retention force. Pushing a wire into a slot and hoping that the slot doesn't widen or distort too much is not a product I care to use. The majority of my working life was in the connector industry and have built, developed and maintained the dies that produce those slots. All I can say is good luck using them with high loads.
