Replacing generic RECEPTACLES

A lot of this information that is given on this thread is wrong and tread lightly when listening to some of this. Most new construction will use 14g wire for 15 amp lines and most use 12g wire for 20 amp, never smaller but you can use 10g. Never assume anything. No builder is going to pay a premium of using 12g wire for 15amp circuits. I have purchased and built 5 new homes in the last 18 years and every builder in every state has done this. We are building a new custom house now and this builder does the same as the other 5. If unsure, open your panel and verify the wire used. Another thing you should do is have either an electrician or your local utility come out and place a device over your circuit to show exactly how many amps you are drawing on the line. There are guidelines on how many max amps you want to draw. For example, on a 15 amp line, you don’t want to go over 10 amps, this is just an example, not sure 10 is accurate, it might be less or more, but never close to 15.
in my latest custom house in my dedicated audio room, I have 6 dedicated 20amp circuits. Cheap to do when building. Large monoblocks, used to use 2 large powered subwoofers, 2 large motor hanss t-60 tt, pre, dac, and other equipment, and the circuits can go fast. Without the subs, I use 4 circuits. Overkill, maybe

How do you people deal with vibrating wires in the wall ? You think it’s nothing ? There is an external vibration and vibration created by the current.

>>>>>That’s quite so. That is why there are such things as duplex outlet covers that act as resonators and large (constrained layer) Marigo Dots for walls and even crystals for walls. Herbies Tube Dampers on power cord plug, anyone? Not only is seismic vibration an issue but when music is playing the walls react accordingly and vibrate like drum heads. The only good vibration is a dead vibration. ☠️

Loserbreath must live in a dilapidated rooming house to be so concerned about the structure not being able to dampen reflected sound waves. And being so knowledgeable about the NEC, has ironically created a fire hazard by stuffing flammable foreign materials into receptacle device boxes. But then, box fill is only a concern for “old men that write books of doctrine”, and not a worry for some ignorant people. That sounds like a big liability when it catches fire and burns down the rooming house or group home or whatever it is. Beware of these risks folks, and keep your homes safe by not embarking on fool’s errands.

Very noble stance sw, it might have been your original intent, however as this thread progresses, recent posts have you straying from your said stance.
