This question already has an answer here:
(I am new here.) I have observed the following. Looks like the majority of active population of this SE is American. When I ask a question, I get answers, for which I need quite a bit of further reading to interpret them. E.g. here the comments and the answers started pretty quickly to explain why the situation in question is not typical for the US electrical standards. But since I am in Europe, it doesn't answer my question.
Other examples include:
- differences in how things are measured, beyond the simple millimetre-inch scaling (American gauges for wire thickness vs. European cross-section area in square millimetres quickly make me lose the point)
- different wire colour codes
- traditionally different methods or materials (e.g. for wire connection here and for wall materials here)
In many cases, it is easy to ignore these differences, the question/answer readability is not impacted. But sometimes the whole point can be missed, or the text may get difficult to read if the regional differences are ignored/unknown.
Therefore I wonder if it makes sense to introduce the "regional tags", to help reading/answering questions.
