The Connextras follow-up on tamper-resistant receptacles

Both videos will go live tomorrow. Timing on that is a little up in the air as I have an appointment in the morning.
Toodles!

The ironic thing is that the Australian and New Zealand plug and socket comes from the 1930's and was a discarded US design. A shame it didn't stick. The Aussie/NZ screw spacing for wall plates also matches the USA. The active and neutral pins/blades have half their length insulated as protection if plug partly comes loose. Protection against Alec's knife throwing... Oh, and a power switch as extra protection. https://www.plugsocketmuseum.nl/Australian-plugSocket_history.html

2023-09-30 04:05:56 +0000 UTCI appreciate how accessible you try to make this. That said, "ceteris paribus" seems like a succinct way to make comparisons. The couching to make that "term" (it is two Latin words, so it's plurality is suspect) accessible might be more trouble than it's worth. Great content, as usual. Really. This channel is flippin' awesome.

2023-09-29 07:35:16 +0000 UTCI'll have to do the some calculations sometime, but I wonder if you could shave down the base of the prongs so the insulation over it is still lower than the metal prong and doesn't wear the contacts in the receptacle. Maybe there isn't enough metal to do that with 15 or 20 Amps.

2023-09-26 17:38:03 +0000 UTCA GFCI won't trip for a fault on the low voltage side of a 24V transformer because the low voltage side is isolated from the high voltage side.

2023-09-26 04:14:28 +0000 UTCSame here, my dad told me that they used to have a similar system to the US 110v system in Amsterdam in his younger years. So 220v was two live wires combined :) I am glad we changed to 3 phase 240v though. And with GFCI on all fuses instead of just in the bathroom.

2023-09-25 19:30:37 +0000 UTCWith these tamper-resistant outlets you're creating a situation where it's harder to shoot your foot but you blow the whole leg off if you manage to anyways. From: a 50:50 chance hitting the live wire together with some other circumstances, which causes current to flow along the side of your body to ground and tripping the GFCI in the process. To: touching live and neutral simultaneously because you stuck two screwdrivers into the outlet, with your left and right hand. Now current is going across your heart and the GFCI won't trip because there is no fault current.

2023-09-25 19:30:31 +0000 UTCWhen I was a kid (say about 2-3 years old) I tried to put screws into the outlet, well, I can say it hurt plenty, that's all I remember :-P... (yes, it was 220V, the GFCI tripped, which might have saved my life...). My father told me that when he was young, there was still 110V in parts of the Netherlands, he said "you just feel it a bit, not shocking at all". Later I got many shocks from working on tube devices (an old tube TV, and of course my Hammond organs), sometimes touching the 350V DC rail, but the voltage drops pretty quickly as soon as you touch it, you just feel it a bit. The worst shock was when I was working on the museum tram, somebody had put some coins in a 600V switch (DC, directly from the catenary, which can deliver several kA!) which had metal handles, that hurt pretty well! They told me to visit a doctor before going home, it is possible that you get heart damage from that which only kills you later! (go to bed OK, wake up dead!) Those tamper-resistant things we also have here, we had power strips in our band, they were worn out pretty badly, almost impossible to get any plug in there... At least: fail-safe π
