An unofficial chapter of the popular Dull Men's Club.
1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.
There are a number of content specific communities with subject matter experts who can help you.
Some other communities to consider before posting:
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

The exposed copper is the ground wire. How's it done where you are?
Grounding wire is just like regular wire over here. The colors we use are: Blue for the neutral, brown for the hot and green/yellow for earth/ground.
There are more colors for other situations, but these are the most used. Black is also used a lot and usually means a switched hot, so brown to a switch and black to for example a light fixture. These are often done in a thinner gauge because the switch can't switch a big load anyways and usually lights don't use that much power.
Normal gauges are 2.5mm2 (14 AWG) for regular 16A circuits and 1.5mm2 (16 AWG) for switched circuits. Keep in mind this is at 250V, so 16A gives you a hecking lot of power (4000 watt continuous load). The circuits are designed such you can even go a bit above this for a short time. The wires are designed to handle 25A without any issue, but are limited by the protection equipment ("fuse"). All wires need to be single stranded, multi stranded can only be used in specific situations, never in permanent installations (except for shielding wires which are usually by definition stranded and will normally never carry any current).
