This potential is what often causes ground loops in your stereo system, where you'll hear hum in the speaker. Depending on what ground reference the various things plugged into your receiver are designed. Some AC potential would exist between the audio interconnect cable shields and the safety ground pin of one or more devices in your stereo/tv setup. These can be hard to track down, often times people will use a cheater plug to unground a DVD player or other device. Very nice demonstration! I just subscribed.
When I was in school, my instructor would say electronics is theory. We forget conductors are somewhat of an LC circuit and will impose a current on a different circuit if close enough. Anyhow, you said the most important thing - which is to respect the power and treat everything as if it was live.
There may be a connected ground at panel but disconnected ground at a light fixture , thats jumped to a receptacle elsewhere with ground connected on receptacle. This can give 15v hot to neutral
And anyone that isn't an electrical engineer will really get it.

I got a request for a video topic. How fake grounds (bootleg grounds) can be dangerous. You can find them in older homes and apartments with metal boxes where there were no grounding wires run. An extra wire is added from the neutral of an outlet to the ground screw on that outlet to fool the inspectors with their outlet testers to appear like everything is grounded correctly. I've seen them many times before and can tell they've been there for years without issue. But on a handful of occasions I'll come across a damaged outlet with the source of the melting clearly around the contact points of the fake ground wire connection on the back of the outlet. What causes this to happen to only some outlets?
Also adding a ground to an older install that had no dedicated ground, by connecting the "new" ground to something like a metal water pipe could energize that water pipe. Then it becomes a potential silent killer, just waiting for someone to come into contact with it.
Would you please explain, if neutral is bonded to ground, why aren’t you measuring 0 volts?! Someone else mentioned voltage drop in another comment, but I don’t understand voltage drop. Thanks!
@@MathCuriousity not sure where to start...do you have any electrical schooling like can you calculate ohms laws and stuff like that for series circuits, parallel circuits and combinations of the both?
@natepeterson7145 I record my content for tik tok and repost it here sometimes. I haven't got enough of an audience here yet to justify making an second video with the camera sideways
@natepeterson7145 I don't think I get trolls just clueless ppl. But on tik tok I average over a million views a month and tik tok pays $1k-$2k a month. Also tik tok has a more of a community of creators posting back and forth, with alot more current videos. And there are more actual code experts there vs diy tutorials on UA-cam
@natepeterson7145 what suck is you tube will give me 12k views for trashing a commenter but like 500 views for an informative video. Idk if tik tok gets banned I might have to be here more.
@@Stevenj120volts that's probably because the way society is nowadays. People like to watch drama vs learn something. I can't get my kid to watch an informative UA-cam video to save my life. Not even to get better at his job. He just wants me to give him the answer. He'll watch people doing motorcycle tricks on public roads all day though.
Copper has a resistance thus a voltage drop between 2 nodes. Looks like your ground wire is a little larger than your neutral. Next play with the capacitive coupling between the hot and the neutral 😊.
As always, thank you for sharing your knowledge.
I'm glad I found your channel. Excellent content.

Why do you lie so much dude
Thanks so much, appreciate your channel.always looking forward to your new posts...
I like your overhead lighting setup
@blockisle9 nothing but the best.....
@@Stevenj120volts I’m not gonna pull on my codebook, but I’m pretty sure you got a couple of violations on that one
Master bater. Your wiring above you is fine. Appreciate the channel
Thank you for your information, very interesting. I think I missed my calling as an electrician.
When I was in school, my instructor would say electronics is theory. We forget conductors are somewhat of an LC circuit and will impose a current on a different circuit if close enough. Anyhow, you said the most important thing - which is to respect the power and treat everything as if it was live.
Does it matter if you have a delta or y ground
The neutral will carry the tension from the hot side when the circuit is continued. You will detect the tension when measured against the ground.
There may be a connected ground at panel but disconnected ground at a light fixture , thats jumped to a receptacle elsewhere with ground connected on receptacle. This can give 15v hot to neutral
Nice
Always. Usable or no? This is the relevant question that your video addresses.
Agreed, always isolate circuits in a box. A neutral will bite you.
I got a question if it was bonded differently at the mirror would it do the same thing
Well done but I doubt anyone that is not an electrician will get it.
Good thing this is an electrical channel
And anyone that isn't an electrical engineer will really get it.

Most likely a loose connection.

@ learning about basic circuit analysis now actually!
How about turning your phone sideways or recorde in 16*9. I can't see good on phone.

I mean in the terms of safety, you still have amps in your neutral, it could still kill you.
The electrical wiring above his head😅.
If electricity is electrons traveling down a wire then what is negative the protons traveling down a wire😮
@@damensutherland7081 only the negative charges move.
Found you. To badTikTok is done with I guess hope TRUMP fixes it.
