In the bay area every home I've lived in had 20A circuits for everything.
The NEC 80% rule is only relevant in data centers where someone enforces it. The time-current curve for any 20A breaker shows that it will take infinite time to trip when you draw 20A. This is correct behavior because 12awg wire can handle 20A indefinitely
- Dylan16807 2y agoDo they actually install the 20A outlets with the sideways part? I don't know if I've ever seen one in person. I guess the outlet doesn't matter a whole lot, especially if you take multiple cables to the wall. But I still don't want to be doing unenforced electrical violations.
- NavinF 2y agoSome outlets have the 20A sideways part, but from a safety/code perspective that's irrelevant. Consider what happens when you plug two 10A devices into a power strip. In the US there are no true 15A rated outlets. All outlets must handle 20A because the electrical code allows any outlet to be on a 20A breaker.
- Dylan16807 2y ago> Consider what happens when you plug two 10A devices into a power strip. I don't know about any argument that depends on such an action being safe. There's plenty of power strips I wouldn't trust with 20 amps.
- NavinF 2y agoThat's just how the US electrical code works. I assure you that every "15A" outlet on the wall can handle 20A. That's why products like this don't have a fuse: https://www.homedepot.com/p/Woods-2-ft-12-3-SJTW-Multi-Outlet-3-Outdoor-Extra-Heavy-Duty-Adapter-Extension-Cord-Orange-990824/301132652 https://www.homedepot.com/p/Woods-2-ft-12-3-SJTW-Multi-Outle...
