Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

The fuse offers per device protection, as well as per room/area.

E.g. you have a lamp that draws 1A. It's cable is rated for 3A. It has a malfunction and starts drawing 10A. This won't pop a breaker, but will overload the cable. Eventually it could catch fire from overheating. If it has a 3A slow blow fuse, it will kill the fuse before it kills the cable.

It also helps to isolate problems rapidly to 1 device.

yeah but the only reason it happened was because you use ring mains.

aint' nothing going to convince me that shit belongs in the 21st century.

The ring main was the impetus for it. However it allows for safe down rating at the plug. My lamps don't need 13A flex. If the only safety system is a 13A breaker, then you're stuck with it, or risking a cable overload
