Church of Tesla -
First video of yours I saw was you and batman grounding that old lab you used to work at. I have learned a lot. thanks
Wow, this is really cool!
Love the channel 😁
Glad you enjoy it!
The 2 to 3 adapters are a thing of their time. Armored cable gave a not the best ground back in the day.
The screw grounded to the socket body that grounded to the electrical box that grounded to the armored cable sheath that grounds to the circut breaker panel that grounds to ground.
i wish i could be my own reference
in Switzerland we have Brown = Hot, Light Blue = Neutral and Green yellow striped = Ground
Tempted to finally get social media to see and absorb any more knowledge, once watched a Eric laithwaite Christmas lecture where he discussed how nice having people who want to listen is, Would love to be one of those happy to listen. Thank you for continuing to teach us all to not be complete d-bags with high voltage and understand coils. The pace of content is Extremely awesome, looking forward to the next
Thank you for watching! I'm thrashing to generate new content as fast as possible. This is my full time job now. If you're interested in supporting it and helping make more please consider kicking a couple bucks in on my Patreon. It really does help more than people understand.
Very intelligently put , thanks!
My pleasure! Thank you for watching and hanging out! :)
Chris you’re my hero!! 😎
I suggest a higher class of role model, but thank you. ;)
Is it just the Fluke 189 model that has the "SUBSCRIBE" function in it as seen at time 6:05?🤣
But isnt the neon sign transformer center tapped to the ground? So your 12kv AC output has a 6kv AC potential to ground. Any RF made by the tesla coil still has some connection to your building wiring. What sorts of issues can that cause? Thanks for these videos, I am rather interested in getting proper grounding and also hate low side current shunts.
Doubtful the metal door knob is actually grounded to anything? Excess
charge of negative electrons (static electricity) jumps to the door knob to balance the electrons? Thank you for keeping us informed.
You're not wrong, but I'm not teaching to that level yet. We're starting simple. It will get more complicated and advanced as we go.
The screw connects to the plate which connects to the electrical box if it's metal, and then that connects to the conduit, if it exists, none of which are meant to be conductors, but they can serve as ground reference, at least, to (for example) eliminate audio hum.
Still don't use those, though. Upgrade your electrical system instead.
I run into problems with what I understand to be ground loop problems when I interface things like amplifiers (generally two pronged PSUs) with computers (generally 3 pronged PSUs). When connected the amps give off very loud 60 cycle hum and the only way that I know to get rid of that hum is by using the 3 pronged cheaters (that you hate) on the computers. Do you have a better and reasonably cheap solution?
Yes :) What you have is called a Ground Loop and it's an old problem in the audio world. I'll certainly be doing a video on this in the future, but for now just google "Audio Ground Loop" and dive down that rabbit hole of reading.
So is powering one of these NST's with an isolation transformer a bad idea ?
It depends on what you're doing. It could be a Very Good idea.
so polarized receptacles are safer.
Yes they are
Polarized are neither safer not less safe on some devices. Mostly old devices that you shouldn't be using anymore anyways. On the other hand some devices non polarized devices can result in a real hazard like having the metal body of a device connected directly to hot.
Being English it was weird seeing plugs in the U.S,/Canada with just two pins,. Do you mind if I ask two probably incredibly stoopid questions? Why did they do it that way and is the ground pin longer than the others on three pin U.S. plugs. I'm terribly sorry if they have obvious, simple answers, I am afraid I am as thick as a planck.
Our plugs aren't nearly as well engineered as the UK standard. Ground pins on new things are usually a tiny bit longer, but not always, and often shorter. However, ours don't instantly kill you the moment you step on one in the dark. So there's that.
@@ChaoticGoodChris Thank you for answering my silly questions I really do appreciate it. I did wonder if you were going to do any more videos of you telling stories, I loved listening to them.
Happy to help, and in that I should tell you that there's a LOT more stories out there. Here's a few things to know. 1. I write books, three of them so far. Here's the first - www.amazon.com/dp/B08B39QPLK it's a whole collection of my stories. :) 2. New stories always post to my Patreon first and you can find a bunch of them there. And 3, I often tell stories and hang out with the guys every night at 10pm on a livestream from my super secret personal channel. ruclips.net/channel/UCbaAyXYMnbQu0BGGPbvxHsw There's a discord server and you can get in on the live discussion if you like. You may even get to kick my ass at chess. :) Come hang out!
@Les also, at least in the UK, the two other pins don't permit connection physically unless the longer earth has pushed in first.
Every outlet in the house I'm renting is installed upside down. -smh
Different jurisdictions specify which way 5-15 outlets need to be installed. The argument for "ground pin up" orientation is typically the possibility of a device plugged into the outlet but partially unplugged, so a small amount of each blade is exposed in the gap between wall plate & plug body. If a conductive object is dropped into this gap (say a metal necklace), if the ground pin is on top, the object will contact ground and trip a breaker/fuse if it hits the hot blade. If the ground pin is down, the potential exists for a metal object to only contact the hot blade without being grounded out. This could result in someone getting shocked, or a fire if it finds another path to ground through enough resistance that it just gets hot instead of tripping the breaker/fuse.
@@Whatsinanameanyway13 the psychological damage of being surrounded by upside down faces is much worse than the theoretical safety they might provide in an unlikely situation.
