I'll be expanding on this tomorrow as I oversimplified some parts and some visuals / explanations. Grounding. Yes, ground acts as a low-impedance path (in TN countries) to trip the circuit breaker and turn off the circuit. One of the best video on grounding and bonding covers this point in incredible detail: https://youtu.be/mpgAVE4UwFw?t=993 This is someone who has built an incredible system teaching NEC and how it actually works. 7W Light Bulb: I didn't do a good job with this visual / explanation. I was referring to the filament, not the wire, the filament provides the resistance and therefore due to Ohms law restricts it to 7Ws. Japan ≠ Best. This is not a video about who has the best system and especially not Japan having the best system. This is about how Japan solved a problem that runs opposite to America (and most countries). They required GFCI first and grounding second which no other country has done. That's the unique part, not the GFCIs in the wall. If you have a favourite electrical system and you got offended, sorry. --- Japan has taken the reverse approach to protecting people from electric shocks, and surprisingly, it makes their outlets safer than America’s. Let’s dive into why! 📰 MY NEWSLETTER Sent whenever I release a new video along with some behind the scenes content: https://lamandrew.substack.com/ 🔗 LINKS TO SOURCES / FUN VIDEOS • The Best In-Depth Video on How Grounding Actually Works: https://youtu.be/mpgAVE4UwFw • How GFCI’s Work (Electroboom): https://youtu.be/GlM6PE2kKVY • Alex (Tokyo Portfolio’s) Video on What a New 2024 Tokyo Home is Like: https://youtu.be/oGsNAP9fySo • Japanese Gov Agency Showing How Products Explode / Injure You: https://www.youtube.com/@nite_JAPAN ⚡TEST / REPLACE YOUR GFCIs GFCIs are electromechanical devices that can fail over time. The simplest test is to press the "test" button on the outlet—it should create an imbalance between neutral and load, tripping the breaker and confirm it's working. Update: You don't need a tester unless you want to check other downstream outlets (outlets that are connected to the GFCI but don't have one) or want to check the wiring (note: some conditions like fake/bootleg grounds aren't detected). I used the Klein RT210: https://geni.us/KleinRT210. Since 2015 GFCIs are required to have self-testing features that checks if the sensors (toroid and driver) are properly working and disables the GFCI if it doesn’t. This is a major improvement in safety and it’s worth upgrading for any old (10-15+ year) outlets or ones that see frequent use. There are many brands but Leviton is one of the best: https://geni.us/LevitonGFC Whichever one you choose make sure it’s ETL or UL Certified which means it’s been actually tested by a laboratory. - - - - - - Creative Commons License: https://creativecommons.org/licenses/by-sa/3.0/ Chapters 0:00 Intro: Japan’s Safety System is Backwards 1:27 What is Grounding, and Why It’s Crucial 2:33 How Ground Actually Saves Your Life 4:29 Deleteme #AD 5:54 Why Grounding Fails in Japan 7:20 Japan’s Safety Secret: GFCI in Electrical Panel 9:09 Spoiler: Japan’s Has Grounded Outlets…It’s Weird 10:02 Why Japan (and All Countries) Use Grounding + GFCI 11:48: Two Practical Tips to Check Your GFCIs Work at Home
