Thanks sir for making this, I can’t tell you how many times I’ve done exactly what you instructed us not to do. The last time was my last though I can tell you that. Now I’ll be sure to spread the word. God bless!
Awesome share the video. It's why I made it.
Thank you! I've always turned my face away after reading to do that a long time ago, but never considered that I should get my whole body out of the way too. It makes so much sense.
I recently energized a short circuit at my house, it caused an arc flash by my hand. Luckily I was not injured. I really never gave much thought about flipping breakers until then. Thanks for posting.
Thanks. Installed a 100 amp box in my garage. I'm not an electrician, and followed as much safety as possible. Never heard about arc flash til I ran across another video. Didn't realize home panels could flash this violently. Thanks for the video
I wouldn’t do electrical work if your not an electrician
"Followed as much safety as possible" -- sorry to say, but the "most safety" you could have followed was having a licensed electrician do your electrical work, no matter how small.
Much appreciated. Will do for the rest of my life. As a survivor of electrical shock, thank you.
Awesome and please share
Thanks for sharing! I always have a flashlight with my face right in the box trying to see which one is tripped. Never again. You are saving lives sir
Thanks for sharing your stories. It's a good reminder to PPE up. I'm a federal high voltage electrician and everyday I see people racking 480V-12kV breakers with no PPE. Some of these guys don't even know 480V is much more dangerous than 12kV :/
Why is 480VAC more dangerous than 12kV AC?
@@michaellapierre1244 The 480V equipment I work with has a higher arc flash rating than our 12kV equipment. Our 480V gear comes directly off 12kV-480V transformers, so there's less circuit impedence which means higher fault current and higher arc flash.
@@astifcaulkinyeras That was an excellent and concise explanation, thank you.
Honestly never gave this a second thought. Thanks for putting out this video
Thank you for this and sorry about what happened to your friends. I will definitely be careful turning my breaker on from now at my home. I didn’t know about arc flash until my boss had a safety share in our daily safety meeting and i came across your video trying to learn about it.
Thanks for this, i had no idea i was putting myself at risk everytime i flipped a breaker.
Great advice, I'm always standing in front of the box like a dope... thanks for this.
Thank you for watching the video and very nice of you to leave a comment.
Thank you for sharing your knowledge.
Wow, lesson learned! I will never look at a breaker like that again
Thanks for sharing this!! The quality of the breaker is important, but that quality won't prevent this neither! I'm going to show my wife this! Good info and sorry to hear your loss...
I buy GE panel boards but install Square D homeline breakers in them . I save money going this route.
This is a good video to watch. I'm trying to keep my crew safer; is it safe to work in front of a breaker that's already turned on? (With eye protection and gloves that is.. would something additional like an arc flash flip-down visor and shirt be necessary or recommended? How often does a breaker arc-flash when it's not flipped? You ever see that happen?
Thanks for sharing...now i need to file in my brain to remember always...been in the trades and have heard of ...seen other stuff 😱
I had old school journeyman teach me. I've been blessed to had them as teachers.
Thank you, bruddah
I’ve been doing this wrong the whole time 😮. I’ve been standing face first when turning on a breaker box at home. Never again will I do that! Thank you!
I did this instinctually as a kid while helping my Dad. He'd send me to run down to the basement and flip various breakers while he was renovating. I didn't know jack about electricity, but I knew that box held a lot of it!
First time he saw me doing it that way, he got mad as hell and told me to handle tools like a man or go play tea-party with my little sisters.
Ha...would you like any sugar sir? I would walk away.
@@GrumpyMountainMan Heh, I was like 9, unfortunately.
My old man had 4 older brothers and was raised by a brick mason with a middle school education. The only dangerous tool I ever saw the man respect was a chainsaw, because he'd personally seen a man lose a leg that way. He was completely and openly scornful of all other forms of potential injury. He'd weld without goggles or leathers, fix the lawnmower while it was running, and close his wounds with superglue so he didn't have to get stitches. Ended up dying of metastisized lung cancer because he refused to go to the doctor. And there went a "Real American Tough Guy". (cough)
Man provided a great lesson on all the stuff you *should* be reasonably afraid of. One of those things is electricity.
Thanks for the reminder 🙂
I used to do Center Pivot Irrigation troubleshooting and repair (440v drive circuit and 120v safety circuit). You can never be too careful! I heard horrible stories from the old-timer that taught me. Put a good, healthy fear in me.
Awesome. Thank you for taking the time to leave a comment and for watching the video. Please subscribe I'm editing more videos : )
Awesome video, thank you for taking the time to make it! I will share this with everyone I know.
Thank you! Thank You!! THANK YOU!!!
..I sometimes just touch the outside of the box from your demonstrated position with my finger so as to ground myself, I think, because I have gotten a shock (static electric)... then I open the door cautiously.. then I, again, touch the beaker just for a moment.. then throw the tripped breaker with one finger/ one hand and the other hand is in my pocket so as not to get shocked, potentially, through my heart..
ExtraCaution:
Have someone standing by safely away to call for help and/ or start CPR if they are shocked..
BeSafe!
I have been hit and partially frozen for a second (Juiced!)
I was holding two electrically refrigerated doors open, as a courtesy, one hand on each door!! 😳 I was knocked off the door by someone who just pushed/ kicked me off one of the doors!! Thankfully I was ok..
Later I found frayed door wires and they called in the electrician...
Good video good information 👍👍👍
Thank you man for this video.
Exactly, everyone that has to work with a breaker should watch this video. I don't know of any electricians that do what you and I espouse, limit contact damage.
Damn I've been reckless as shit with breaker's thx for tha life saving info .
Thanks for the video I’ll be doing it like that from now on.
Awesome!
I have a dumb newbie question maybe you can answer for me. The electrical code here required ARC/GFI breakers. Do these new breakers prevent that ARC flash from happening? I had never heard of an ARC anything before so its all brand new to me but I rarely deal with electrical stuff mainly because I have a healthy respect for it LOL (ps thanks for the updated video!)
They do help. But they are more to help in prevention. Still never look a breaker in the face when you turn it on.
By the time AFCI strips- you would probably already being burnt.
an arc rated breaker helps prevent small arcs from happening at an outlet when you remove a plug or within a box if there is a bad connection. Helps prevent fires.
Tips - as you look away as you turn on the breaker - there are better ideas to avoid arc flash injury......
1. Best to turn on that breaker with arc-rated gloves so you can save your hand just in case the flash happens.
2. Use a non-conducting square block that will not catch fire, that can divert the arc flash away from your face. No metal of course because the arc flash will melt metal no matter what it is...and the flash contains electricity which will fry the metal and give you an electrocuting shock.....Plastic is best. Avoid wood because if an arc flash causes fire it can burn your hand.
Oh my!! Thank you!
Aren't you are overstating the hazard of a dangerous arc flash, at least in a typical residential panel?
Until a breaker goes bad...and they do...
Good advice
is this for regular house with regular electrical panel too
Very much so.
@@GrumpyMountainMan damn scary., didnt know that till i watched the video
Never knew this. Thanks man!
Glad you could use it : )
I had absolutely no idea! I'm one of those ones that looks at the panel. No more!!
Awesome thank you for watching and taking the time to leave a comment. Be blessed.
My wife and I turn off our water heater every night at the breaker panel and turn it on during the day. Should we use something like a wooden spoon to be safer and should I install a switch at the water heater? Also the same sometimes for my well pump we may turn it off at the panel if we are going to town for a couple of hours in case a water line breaks.
Just don't have your body in front of it nor look at it.
Thank you for watching the video and for leaving a comment. Thank you for your time!
Distance is your friend. Get a long wooden stick to operate the breaker. That's what I use when I have to manually operate high voltage breakers.
i just wired my basement and never even thought about this. wish someone told me this a decade ago. thanks for looking out.
So glad you could use this video. Thank you for taking the time to watch and leave a comment.
Thanks you brother
Omg wtf . I had an electrician come I stall a box for my hot tub . He was literally sitting right infront of the box . I myself have had to flip my breaker . Now I'm too scared . Thanks for the info I will definitely be more cautious
Do amps matter? My PV solar panel array puts out @ 313vdc, 10 amps. My sense is that arc flash involves a LOT more amperage. I do know that 10 amps of 313 is serious business.
Thank you very much, Brother!
Thank you so much. Me and my pops recently installed a 240v 30amp line for my mining rigs at home. I've always just turned on the breakers face to face and this shed some light on that. Thank you so much! Also, what PPE equipment would you recommend for preventing burns? Thank you once again! you're a life savor literally
Just be safe. Always wear glasses and cotton.
Your 'mining rig' is trashing my planet. Please reconsider.
@@Steve-wz5pz no
I was wondering what voltage panel was John working on. 240,440,600,1000.
I know a ark blast can happen with any voltage. But I have been told ppe equipment is only required with gloves, face protection for house power supplies being 240 voltage.
Thank
Nicley done..ive been hit..no fun...220..dame line thought I was the load
Ha sure does suck!
Thanks man !
This is terrifying. My breaker got tripped for my room the other day and I popped it back on. I never knew this.
Yep...true story for sure
Well. Depends on situation. Breakers (in europe at least) have 3 markings, which are something like for example "10C 6000" or "16B 10000", the first number being trip current, second being characteristics, third being short current that it can withstand and break. On top of that, here in hungary you have to have a series hrc wire fuse if it's over 32 amps. I really don't see a situation where an arc flash in a residential setting could happen here if the equipment was made in the last 2-3 decades. Also please keep the cover plate on, it's there not just to keep you out but to keep the arcs in
Awsome
In general, arc flash incidents are highly improbable on systems operating at less than 208 volts phase to phase (120V to ground) when fed by less than a 125 KVA transformer (very typical of most office and home environments). 120 volts does not provide sufficient energy to cause an arc flash hazard. Most 480V electrical services have sufficient capacity to cause an arc flash hazard. Medium-voltage equipment (above 600V) is higher energy and therefore a higher potential for an arc flash hazard.
Most breakers in a home in the US are 120V and not more than 20A. Dont get paranoid.
Whatever internet Engineer..I've seen more 120v breakers blow up in a Journeyman's face ,then any 480v...real world vs paper...
@@GrumpyMountainMan I wonder if this occurs when you have a dead short in the line somewhere, you think it's clear so you turn the breaker on, and the breaker fails and locks in the ON position. If the utility transformer is close enough to the house to produce a high fault current, I can see where 120 or 240 could produce an arc flash if it's a dead short and locked ON.
I'm scarred to touch my breaker panel now...
What happens when you get the arc flash when looking away Is it still deadly or enough to cause serious damage? If so wouldn't rubber gloves be an good idea? I'm really curious to learn as much as possible before I build my own off grid.
Rubber melts...you look away to protect your eyes
So the circuit breaker tripped because of a short down the wire somewhere.. and here we go monkey see monkey do we go turn the breaker back on not knowing there's a dead short in the wires and as soon as those contacts close BOOOM high current flows straight into our faces
Wait, so I'm pretty confused right now. Does this apply to household breakers? You discussed how to flip the switch, but why exactly is this 'arc flash' happening? I definitely didn't know this...
Mayber your lower voltage standard is responsible.
I dont understand how this can happen...
Thats why I worry it could.
Skipping corners will cause an accident respect the trade
Amen to that!.
I’ve been doing it all wrong!!!
And most of us think only high voltage can flash!
Glad you could use the video.
We had a 480 V. 30 amp, Three ∅ can arc out on us after changing out the motor at Lenape Forged Products years ago. Unbelievable explosion and fire that shot out. Luckily the (remote) start button that was near the motor about 15' away was used to for the initial startup, and not the one on the can door.
110 volts is not as deadly as most think... Now 220 volts and beyond is a different story, but you should know this already!
