My friend studied physics up to Phd level. He used to laugh at the ignorance of electricians vis-a-vis electrical phenomena. Most of them are little more than monkeys who learn to connect this colour wire to that colour terminal.
Delivery was too fast and contained little real explanation. Using trade jargon is not the same as explanation. Knowing what something is commonly called in the trade does not explain what it actually is and actually does to someone not in the trade. As a teacher, you fail badly. There are underlying physical principles which must be understood. Knowing the relationship between potential difference, (volts), current (Amps) and resistance is only the beginning of understanding electricity.
When dealing with electrical, must be very careful, DANGEROUS
@TheMrSanchos Ya knock yourself out reading the rules… Try reading the Electrical code or the Delmar…It takes 7200 hours on the job and in school to know the rules and understand there meaning… But by all means play the game and give me a call when you see smoke…
this is why we have to go back and fix so many homeowner projects, thanks for providing us service calls… dumbing it down and encouraging unsafe handling techniques is not a good plan. Not once did I hear “never work on a live circuit”. seems real simple requirement for a homeowners safety. again, thank you home depot for all the call backs and re-work.
WOW….so many improper statements in this video. I guess it will serve for a purpose but again alot of incorrect statements are contained in this video. Hope they address them but I wont…lol…unless they pay me to visit all their stores and train the staff…;)
secure connections with electrical tape??? Not in my house!
weird looking cotton field
@hitachi088 u have to know the code
its 120v and 240v when it enters your home 240v for the high power devices and 120 for lights and outlets thats a better definition
“When a circuit breaker trips the current flows harmlessly to the ground?”
No, … when a circuit breaker trips, it interrupts the flow of current to anywhere unless there is a short. In reference to the wider contact on a two wire plug…”this is a safety feature that keeps power from running to an appliance, even when it’s switched off?” That has nothing to do with power running to an appliance, other than to insure that the case, covering, etc. is at neutral potential, not hot!!! Dummy
@ocxic go on, continue posting. you amuse me.
@hitachi088 No, I defended my point in the post above where I mentioned the battery. You have yet to give an intelligent response. Since that post you have been nothing but insulting and condensing. You have offered no meaningful response to back up whatever point you’re trying to make, other then to call me stupid. You are ignorant and childish, and i will have nothing more to do with you.
@ocxic that is the only thing you can think of to defend your point? pathetic.
@hitachi088 Nice to know the only thing you can do is insult me rather the provide and intelligent response. It just further proves that you do not know what your talking about.
@ocxic prove it faggot, the thing you said in your other post were completely bollocks, the only thing you have proven so far is your stupidity. welcome on the internet.
@hitachi088 What does Wikipedia have to do with anything?, and I’m not a kid, I’m a 27yr old licensed electrician, and know more about electricity and the way it works then you. Dumb ass.
@ocxic thank god wikipedia! you are a funny kid, i admit that. you can go play with your solderless breadboard now, ill let you go.
@hitachi088 Your bodies internal resistance is so high that the voltage provided by a 9 volt battery is not enough to push that much current through you. Touch the battery to your tongue and you will get a much different result. As a matter of fact the amount of current moving through your tongue is enough to interfere with, or stop the beating of your heart, but since the battery’s contacts are so close together the electricity does not flow across your chest, and therefor you are safe. Dumbass
@ocxic am holding a 9volt batery in my hand, touching both side. why i am not death then? cause your stupid.
that’s like 9Volt 2-5amps.
@hitachi088 actually .015 amps and ANY voltage can kill you.
@kaang69 ok, you’ve removed a little of the confusion I had.
It’s hard to expalin in 500 chtrs. The ground/bonding conductor is your safety. All metal parts of your system are BONDED to each other. The GRDing is really only the part where your ground wire connects to earth either by using a water line (street side of meter) or grd rods (usually 2). After this, everything is really considered bonding. There are lots of arguments over this however. If your Gnd wire is brought to you NRL bar, you must make sure the bonding screw is removed from you panel.
@zer0dahero Grounding & bonding are very confusing even to a lot of electricians. Your neutral is like the sewage line in plumbing. It is the return for the circuit. At one point ONLY, usually the panel or meter base, your ground & neutal are connected. This makes them all the same potential. They should only be connected once so the circuit only has one path to ground. Circuits need this return path to ground/neurtal to be completed. If they are connected at more then the currnet will circulate
@kaang69 I’ve been trying to understand home wiring , its more confusing than I thought. I’ve spent 2 hours reading anticles and post which state that a ground should never, ever, be connected to a neutral. Yet, they both, gound and neutral, conect at the panel? which is it? If they connect at the pannel, why can’t they connect, say a few inches away from the pannel, or a few feet? or at the outlet? If you have a few monents can you point me to where I can figure out what I’m I missing here?
