- How to rack out the VCB
• HOW TO RACK OUT VACUUM...
Our Bow thruster VCB cannot be opened hence it cannot just simply rack out to check what is wrong to the breaker.
Here is the step by step procedure I did in order for me to fix the trouble. I hope you can learn from this video.
In case you haven't yet watched the step by step procedure on how to rack out the VCB just click the link below. #leckyjake #lecky #electrician #ETO #marineelectrician #seaman #seamanvlog
• HOW TO RACK OUT VACUUM...
I don't know much about ship equipment. But it is nice to know that the rule that you can fix 90% of the things with WD-40 and Duct tape also applies to ships! :)
I've worked on many boats from steam boats to trawlers 3 key things any boat needs 1: duct tape 2: zipties 3: wd-40.
Is this just normal lack lube situation or a temp fix thats kinda sketch
....and bubble gum.
Don't forget a hammer.
@@tranceman9670 based on that, i would like boats
Just FYI WD-40 is a terrible lubricant. It's mostly a solvent. It works well for freeing stuck things but needs to be followed up with a proper lubricant otherwise the problem is going to return.
Correct it's not a lubricant at all it is a water displacer , it chases the water off evaporates, and leaves a residue.
@@bryanlatimer-davies1222 that's were it got its name WD and the 40 was the 40th try at the water displacement formula. Was a contract with the military for a water displacement.
And then the residue becomes tacky with contaminants, not good for periodically moving parts. As soon as I saw the can coming out I was thinking ffs.
@@ross82 same here. WD is not a lube, it's far too light an oil (mostly petrol) for that job.
WD-40 is a brand these days. They have a ton more products than just the "original formula".
You may want to look into the life cycle of these VCBs. That Bow Thruster VCB is sitting on around 5000 operations which is nearing on the limit of its mechanical life, that is probably why you are starting to find signs of wear internally.
The same report was sent to the higher ups. Thank you very much
Nice to know that WD-40 has its uses even on multi-million dollar ships.
Ah. I just used it on my small 25ft sailing boat to try to fix intermittent contact with my automatic tiller. The WD40 for cleaning contact that is. Small world.
all faults can be fixed with wd40 and duct tape :D if it's not moving but should move then wd40 , if it's moving but shouldn't then duct tape :D
It was developed for use in the Atlas missile program, the WD stands for Water Displacement. So yeah, its been used for multi million dollar applications quite a bit in aerospace and aviation. As a lubricant, I think it sucks. Its a pretty good contact cleaner and fairly mild adhesive remover.
@@SteelDoesMyWill glad you pointed that out. The history of WD40 is interesting. 40 tries and an RFP from the DOD for a magical WD product that would preserve ICBMs.
It's not really the right product for this application though.
As someone who grew up far from to ocean, the idea of 6600v equipment on a ship is a little mind boggling. I realize that heavy equipment needs high voltages, but the idea of multi-thousand volt equipment on a ship is something I never would have thought of.
Thanks for the video!
6600 would be a main feed on a buss....the buss will feed many items.... none of which is 6600....
@@mr.h4714 this dude has it. It probably doesn't receive that voltage often, but it has the potential to, so it's labeled as that.
There's probably more and longer wiring in these large ships than in an entire town. And, all specialized uses. Long runs + high voltage == lower current.
Well presented docuentary of this project... change those dampers 👍
@@roetemeteor 6600 will be the main bus fed from the generators and it'll stay at 6600 phase to phase. After it's distributed from the main switchgear, then it may be dropped down to 480 or similar. But the larger motors (like azimuth pods or thrusters) are usually fed the primary bus voltage to save on motor size and copper.
Finally, found a real ship maintenance !!!!
Thank you youtube recommendation!
We have more mechanical issues with our high vol switch gear than electrical! Lol. Back in the day, the buss rails and plugs were made of all high quality parts and with regular maintenance would never fail. Now they try to save money and use cheap stuff. Plastic instead of metal, pot metal instead of billet and so on.
You are a living legend, thank you mate.....
Even im not electrician, i really enjoyed all your video. I always gain new knowledge from those videos
Thanks for this wonderful comment
I learned you followed safety proceedures and exercized the equipment and that is all it needed.
Thank you sir... It's very helpful for Trainee ETO... 🙂👍
I love this video, so interesting to see the electrical system of a large ship, subbed and looking forward to more videos !
Thank you very much
I always learn something in your every video, thank u lecky jake😁
Thanks for the interesting video. WD40 is actually a poor lubricant. It is a water displacement fluid and tends to evaporate and disperse over time. A good quality synthetic oil or grease would be much better.
Mad skill, mad ability, mad knowledge.... awesome video, good sir!!!!!!!!!!!!!!!!!!
I just found your channel and wanted to thank you. This information is extremely interesting.
Great job and methodically carried out just as it should be.
I'm always excited watching your videos, it feels like having a preview on what i am going to experience once i become an ETO. And i think it will be a great opportunity to work with you sir.
good luck to your journey
This is so good to find!! I’m leaving soon for the navy as an electrician for the ships :)
Wow, never knew the switch gear could be fouled enough to over come the spring tension? We rack and rotate with spare , rebuild and test.
Crumbling rubber or elastomer damper seems to be what he commented on.
@@imconsequetau5275 is there a conditioner they could use on the rubber or maybe the high temps would just burn it off
@@deborahchesser7375
Probably degraded due to ozone, friction, and collisions, so the damper needs to be replaced. Recent innovations allow various thermoplastics and rubber to be molded together, so I'm wondering if it could be re-engineered to be more durable, or substitute with a polyurethane.
Back in the day, IBM made a typewriter with a _fluid_ damper, (piston and cup), which trapped air for deceleration of the carriage at the end-of-return. That was a large part, but they _never wore out._
And with all due respect, I would be sceptical that a quick clean up and squirt of extremely low viscosity, short service life lubricant is going to offer much of a fix. Pessimists though eh?! Ha.
@@dmacgyo I agree. Probably more a case of the manual trip freeing up what was stuck. Will happen again given time. Breaker must see alot of ops thou so understandable if its worn out
Hello, thanks a lot for the video provided. Could you please give a final conclusion about the reason for not opening the bow thruster breaker?
thank you so much for sharing this video. got so much information
Thank you lecky for sharing the experience. I hope we work some day together on a same ship. Cheers!
thank you
Ayos... 👍👌
Salamat lodi
@@leckyjake Tisoy for the win!!!
That's some job you have! Interesting video thank you. 👍
most educative channel by a mariner ...nice work sir
Oh thank you so much for the wonderful comment
Interesting video, my Dad was an AB on ships in the 1950s - 1980s based in New Zealand. Mostly bulk carriers I think. 👍 I will sub!
thank you again sir..Kip safe always!
Thanks for the support
Nice work. Very interesting engineering subject.
Great man, you are professional thank you
FINALLY,someone talking about switchgear that I can UNDERSTAND!!
Great Demo. Keep it up Good Luck
Good Job Lucky Jake ! ! I am glad you are being extra careful & also that you have the necessary High Voltage Suit which confers the extra protection that you need while onboard & working with dangerous equipment. I would have the Captain always remind everyone during a all hands meeting ; that No One UnTags Any Valve or Switch or Breaker that has not been placed there by themselves & all safety tags must be known & approved by at least one supervisor ! There is no reason to lose the ship or anyone aboard it during these modern times. If all safety procedures are followed then everyone goes home with a smile & pocket full of money ! Good Luck , Lucky ! I had 2 electricians electrocuted while I was in The U.S. Navy & I can still smell the burning of their bodies in my mind when I recount the incidents. Keep yourself & your crew safe , keep them sober & get rid of anyone with a drug or alcohol problem.
Thank you very much for this wonderful comment. Messages like this will help me alot to improve my dealings with safety and to be better at my work. Thank you
Thanks for your expert input to the channel.
Is WD40 the correct lubricant for the application? I thought there would be a specific silicone grease required with low VOC.
Exactly ^
It really isn't the right thing. WD40 is a dismantling lubricant and this will only work as a short term solution.
WD-40 is not even a lubricant it is a water displacer
You are correct. I just worked on similar voltage stwichgear on a project and we used the correct silicone grease where needed. Perhaps it's not something they keep on board but I think they should. That being said, a cleaning with WD-40 might be all they needed anyway.
@@justinkase1360 Deoxit F5, take it or leave it lol
Yea very useful video for people who don’t know how to change a lightbulb
tanx a lot lecky for the very interesting leaning video you created.... hope to see more... gid bless you more
Compare this video with a video from a year ago, man, your English is improved! Good job!
Fellow ETO here on OSV's in gulf of Mexico. My chief wouldn't let me touch that till we get in port if it's stuck closed. Since I would still have bow thruster operational for docking. Now if it was opposite, get er done now!
Chiefs are a funny breed.
With your knowledge on this issue, You are worth your weight in Gold.👍👍
Well done Kuya 👏
Thank you
Legendary ka talaga sir
Nice one sir.thank you
Usefull information.
Good Job, and good Vlog as well.
Good idea wearing the HEV suit. Never know when you're going to have a resonance cascade.
i had same issue on VCB, but in mycase we found broken parts( plastic part), we replaced with spares
Well done! 👏
It’s good to see the technical library right next to the control panels. Great for efficient fault finding!
Nice switch bounce on the VCB. Good example why they have springs and dampers otherwise the switch can bounce back partially closed and arc weld itself closed.
Try CorrosionX for lube, it's dielectric and is safe for these parts providing better lubrication.
8:55 looks like you either have a control issue or relay/contact chatter. That looked like a double hit.
Well done! Never cut corners when it comes to safety. My job is similar but it's on land. The highest voltage I deal with is 480v 3 phase from the grid. A ship at sea is its own power plant! Fascinating.
@MichaelKingsfordGray #1 he isolated the problem area. #2 he released any stored energy. #3 he used the proper PPE. #4 he tested for voltage. He didn't cut corners. He was safe. As far as the wd40 goes I don't think rebuilding or replacing the VCB was an option at the time so he gave it a few squirts. The bow thruster's back on line and he is alive and healthy. Arc flash is no joke especially at six thousand volts.
That was a good job my friend!
I don't work with HV but this was cool to see, subbed
Thank you sir.
Thank you
Finally ……… now I can fix my bow thruster. Ive had numerous hit an runs in my ship since the little bastard broke ….. thanks Bro !!!!!
Great video!!thanks

Thanks
Very Informative video I loved it ❤
The best talaga

Wd40 not for lubricant. But to remove the hardened rust or corrosion. I think they use it for that. Then wipe it out. We don’t know if they used a grease specially for the contacts. But he did a good job on that lever
Wonderful vídeo
Amazing video. Next time my home light circuit breaker trips, I'll head straight to the 50 cal arc flash suit and ensure the VCB is open along with the MBT. 😂🤦🏽♂️
🤣🤣🤣
Good day sir Lecky.... WD-40 lng katapat.. ingt palage sir lecky
thanks for sharing
SUBSCRIBED! love this stuff
You are the man !!
Thank you
amzing how wonky and persnickity electricity gets the higher the voltage stay safe
Thank you
It must be a good feeling knowing you got such a serious arc flash suit on board. The danger of 6000volts is kinda impossible for people to understand until it blows up in your face.
I saw a guy literally blow himself to pieces in a generator room, high V/AC scares the shit outta me.
I used to tour some factories and see “medium voltage” AC motors. While that does not sound scary at first think about this, 0-600v is “low voltage” and up to 4,160 volts is “medium”. I didn’t even want to look in the direction of those motors or their feed boxes!
What face?
not very good arch flash suit
High Voltage doesn’t really scare me… Amps contain the scary magic😉
Mantap
It was a great day when VCB's replaced OCB's in Power stations
I disagree. A well maintained ocb will last forever. Give them regular oil changes and check split pins etc and they are bomb proof.
@@whippetquick3527 They also have a nasty habit of going bang, I'v seen a few.
The big advantage as far as I was concerned was that VCB's are much easier to manhandle for isolations, some of our 11kV OCB's weighed well over a tonne and they take some dragging out when you are on your own.
I've only seen 1 that went bang. Have to admit that when they go they really go. This one took out an external wall and part of the roof. They do need more regular maintenance than VCBs and luckily the one that went bang hadn't been maintained by us :-) I don't miss hand cranking the things either. Those tanks are heavy.
Great!
Thanks
Great video!
Thanks
Thank u ❤
Thanks
I had to spray wd40 on a 135kv vcb. The trip relays opened but the mechanisms had dried out grease on them. Gave the mechanisms a couple squirts of wd40 and then BAM! They slammed opened.
It’s vacuum engaged ? Cool.
Very nice master
Great video. ! Great teacher. ! I would definitely want you aboard !
Thank you very much for your wonderful comment
It's good that you have the proper PPE for jobs like that.
What is the minimum voltage on which you would use that suit?
According to the NFPA 70E, the Arc Flash Rating of the equipment being worked on determines the proper PPE.
PPE appeared to be Category 4:
40 calories per square centimeter suit.
so cool!
Thanks
I sure hope when you get to Chile, you attend to the contactor mechanism service and lubrication properly since it is already compromised. WD-40 will do for now, but not for the long run.
WD 40 may be a better choice as it won't cause problems with the electeical. Except perhaps from dust accumulation. Would for example, a silicon lubricant act as a semiconductor, and be a bad choice around electrical contacts?
@@onradioactivewaves Silicon and silicone are about as similar as water and hydrochloric acid
@@alakani yes I know, but I was referring to the dielectric properties. There are different types of silicone. I know some have good dielectric properties, I suspect the lubricant do not as much, as the better lubricants have smaller molecules.
TY TH-cam. I have no idea what i just watched. But it was fixed with WD-40 which blew my mind. I imagine this is temporary until they can get the part they need on board replaced.
Magandang video sir.. Salamat Po.. Talaga naman 6600 volts.. Amps? Greetings from Switzerland.. ✌️

Great Thumbnail and title, you peaked my curiosity.
I’m surprised you don’t carry a spare VCB. It would have been easy to just swap it out and send it off for repair.
Send it off to where? Overboard?
That makes no sense....why would you do that when you are on a ship and you have to improvise and make things work?
At 6:50 he sticks his finger into the hole in father front of the panel. Then explains why he needs the protective suit. I don’t understand…
nice catch
The suit is for flipping the switches. These types of high voltages switches used for industrial purposes can dangerously arc flash when thrown, killing or seriously wounding any workers near the panel. The suit helps protects from burns if the panel deicdes to arc flash.
You really should put in more in depth explanation of why are you going and using this approach and what you needed to consider. Mainly, why the VCB could be opened with no load on the bow thruster? Is it some kind of interlock, or...?
It was actually specifically mentioned in the beginning that the vcb cannot be opened hence need to isolate the bus tie to manually open it so that it can be disengaged safely from the bus bar.
@@leckyjake Is the VCB simply for fault protection? Is there some functional switching downstream of the VCB?
The part where he uses a stick is like when I wire a switch or socket up in my hose then use a wooden spoon to test switch it 😂
Sir Lecky Jake can you advise me that for any electrical system how I have to start ?from where I have to start? What should be in my mind??
Interesting to see that they use different color coding on the panels. For the racking they use green for "disconnected (i.e. OFF) and I'd assume red for connected (i.e. ON), which is what I'm used to seing. But on the panel lights the colors are reversed. Seems a bit confusing to me, is that a local thing?
I am entirely not one to speak on this system specifically, but I've seen on a printing press where 'contextual' indicators appear to clash: safety-context (red==danger; technician should stop//green==safe for tech to proceed) and operation-context (red==system/mechanism is stopped//green==system/mechanism is running). I too am curious if this is the arrangement for these indicators!
WD-40...That's bloody awesome!
Velkommen til Chile.
Hi my friend Leckyjake, I'm speaking from Brazil, I'm trying to find out about the Alj281 from the Daikin container.. Other than the SMV valve, the SMV coil, and the solenoid coils, what else can cause this alarm?
Thank you sir for sharing your experience and knowledge sir,, are you a Filipino?
Yes sir
