Thank for watching We will be uploading part 4 with a diagnostic section soon that will bring the all 4 videos together in this series. Hopefully it will be of use to folks. Sail Safe. Ant and Cid xx
I love you man for doing this explanation it helped me a lot. i watched many videos but the more i watched i got more confused. I stoped the video and calculated, and got it right which made me smile like a kid in a candy store knowing this will help me redo my fathers old boat and bring it back to life without paying to no one cause i cant afford labours anyway. So thank you and keep it up, you got a new subscriber! Greetings and love from Saudi Arabia 🇸🇦
Khalid. Thank you so much for your comment. It made us smile, knowing that the little we give, brings knowledge that helps. Let us know how you get on with your fathers boat. We are always interested to see how folks progress. Sail Safe my friend. Ant, Cid & the pooch crew.
I loved it even though I'm somewhat versed electrical through past jobs I like the way that you explain things my uncle was a certified electrician and he talks just like you he was an engineer bless his heart he wasn't here with me long enough I sure you miss him and it sure did sound good to hear coming out of you your video was very instructional put together very well you explain things cleared to the point thank you sir
Brendon. Thank you! Like you, I had a mentor that is no longer with us. His sayings like; "It's broke you can't make it worse". "If you know how it works, you know how to fix it". Stay with me now. He gave his time free and always explained slowly in terms that were easy to understand. I always try to follow his example. Hope you enjoy our other videos. You can also find some interesting stuff on our website; www.svimpavidus.com/ Sail safe! Ant.
I am so glad I found this video! I'm redoing the charging system on my Searunner Trimaran but have almost no knowledge in the world of 12v. This made it much easier for me to picture my calculations and needs
Oh i could marry you !!! thanks so much for this great description on basic Electrics. Have a new yacht and trying to understand 12v!! you have made my day thx.
Clearest explanation of electricity and systems I’ve come across. Your communication and teaching style are incredibly clear. Thanks for sharing your knowledge. 👍😃🙏
Thank you. We aimed these videos specifically at folks that may have little or no knowledge and want to develop the skills. A step by step guide that builds on the last video. Enjoy the series of videos and please share, like etc. It all helps us to make more videos, share our knowledge and just help folks out. "If you know how it works you know how to fix it"! Sail Safe mate. Ant, Cid & the pooch crew.
I'm refitting my sailing boat and l have to do all wiring. Very well explained now l understand way much better than from any other who was talking about the electrical wiring. Credit for you.
Thank you Debbie. The intention is to build folks knowledge slowly step by step so they can start to do their own work or at least have a clue how things work and then fix them. Glad to have you on board. Sail Safe, Ant, Cid & the Pooch crew.
Thank you! This is the video if been searching for. I know nothing of electrical matters and after buying our first boat I really needed someone to break down the basics for me!
Thanks guy's. When you get a mo be good to discuss the way we do the next few in this series. Get he basics out the way then perhaps AC, Transformers, Chargers, mains safety? How to fault find AC & DC? Got ant thoughts on what should be the running order? Sail safe and see you in the med soon! Ant & Cid with the pooch crew xx
Great how you’ve simplified things , although going to watch a few more times 🙄 as not the sharpest tool in the box 📦😂, sure will be of great benefit to boat owners .
Hi Shaun. Your a smart cookie. Dont over think things! If there is anything you need clarifying just drop us a line. Happy to help out or just explain better. The plan is to make a few as a how to box set. Starting with the basics and going on to the practical. Little steps that folks can re visit at any time. Thanks for watching as always. And thanks for the feedback. Sail Safe! Ant & Cid xx
Thank you for watching. Be sure to follow the other videos in this series and the ones on engines and maintenance. Folks seem to get a lot from them and like yours we get some lovely comments. Sail Safe, Ant, Cid & the pooch crew.
Good vid. I'll show it Carol. Getting 460 watts now regularly from our two 240watt Panasonic hit panels not that they are mounted properly. Very pleased
Thats great Stuart. Do you know what your producing in watts per day? The victron app can tell you this. It would be interesting to know. Glad its all worked out. Woody tells me hes not been below 90% and is now thinking about a big inverter to run the washing machine!!! Sail Safe mate Ant, Cid and the pooches.
Hi guys, although Ryan already understands a bit more of this than me, the stuff about the calculations was very interesting and I (Faye) feel I can now begin to understand what Ryan is on about when he talks about watts and amps ect!! Very informative video, thank you!
I've always hated dealing with electricity. Now that I'm interested in boats if feel it's imperative I learn. You have provided the best explanation. I'm looking forward to more. 👍👍👍 A newbie subbie. Fair Winds!
Thank you Clay for your kind words. We look forward to putting out the next part. Ant is half way through the drawings now. Its good that folks are getting something out of our little channel and the main reason we do it. Sail Safe. Ant & Cid xx
This is a great series. I am totally new to boating but wanted to understand how it all works. Thanks a lot for this wonderful explanation. I will be getting back here a lot, I guess :)
Thank you! We feel very humble at all the lovely comments this series is bringing from people. As I said at the end of the last video we just want to help folks out. It is so rewarding to give something back. What is it they say? Give a man a fish you feed him for a day. Teach a man to fish, you feed him for a lifetime! Be sure to pass on what you learn to others. Teach them to fish too. Ant.
Thank you very much for this very useful guide (and all your other videos), 8 minutes well spent watching and learning. I do a lot of solo sailing so if something goes wrong - I have to fix it. Safe sailing to you!
Kevin. Thank you. We really hope the BEME series would be useful and thats why we did it. Judging by your comments and others it has been. The solar videos were much more involved and took a lot of input and thats why we asked other video channels to add to the series. Because every boat and budget is different. The BEME is a playlist on our channel. We are thinking of doing a series called Boat Mechanics Made Easy. So we can pass on something to others that we have learned over the years. Do you think this would be valuable to you? We now have a web site and we are slowly adding pages and other things including blogs, and even a technical page. Cindy is working on a recipe page for boaters . It is in development but the basics are there. Check it out at; svimpavidus.com We are always happy to get feeedback and chat to subscribers. So dont hesitate to keep in touch on YT comments or on our facebook page. Sail Safe Guys, Ant, Cid & the pooch crew.
Im a commercial electrician but i have never worked on a before, but if you understand electricity you understand electricity. A friend called me and said she was watching TV on her boat for about an hour then all the power shut off and the individual breakers started reading reverse polarity. this should be impossible considering no work has been done. The main breaker has 120V to ground and is not reversed when i checked. I can see the hot coming off the main output into the input of the other breakers but i ran out of time and didnt check the reading, but im pretty sure its correct. What would be the next thing you would check? Im assuming its a equipment problem somewhere not a wiring problem
It sounds like someone may have may have fiddled with the main supply. There is nothing on the boat that would cause this. However, reversed polarity also presents a serious shock risk. Turning off a breaker appears to remove power from the circuit because it turns off all appliances connected to that circuit. But with reversed polarity you have disconnected the appliance from ground, not from power. The circuit is still live! On most boats 70ft and under, the shore power lead supplies the vessel with 110v AC power. The shore power cable that connects the dock power to your boat has 3 cores inside. An Active, Neutral and an Earth. Now because of the way switchboards are wired. Your AC circuit protection switches the Active conductor. Your Neutrals all get join together and your earths all get join to each other on bus bars. In some switchboard installations, not all, there is a connection between the Neutral and Earth bus bars. This is ok and safe as long as the Active supply doesn’t get connected to it. When reverse polarity occurs from the dock side supply. You now have switched the Active and Neutral conductors around and the Neutral and Earth bus bars that were before safe, become live. As I mentioned before, in some cases there is a connection between the Earth and Neutral bus bars. If the Active and Neutral conductors are now switch, not only is your Neutral bus Active but so too is your Earth bar. This earth bar connects to all your metal frames and items on your AC systems. Making them Live. This can create a dangerous touch potential and is very serious. How do you fix this? Well the first thing is to turn off you main switch that supplies your main switchboard and unplug your shore power lead. Most marinas have a service man who can come and change the wiring of the dock power outlet to suit your vessel. If you travel around a lot from dock to dock, one option is to get a reverse polarity switch put in which you can use to just turn in this situation and continue using your boat without rewiring anything. Reverse polarity lights and this switch are easy to install if you have room at your switchboard. If not they can be installed together in a secure location nearby for easy viewing but must be in line with your shore power input cable. Checking with this system or a polarity tester is always recommended for the reasons I stated above. Hope this helps Ant.
Yes, that's it. Now you know the law(s) and how they work you can download an app to your phone that will do all the math. We use one onboard and it saves all the mental maths or scribbling on a post-it note. Thanks for the feed back its great to know these videos are of interest and folks are getting something out of them. Sail Safe. Ant.
This is the best explanation of watts, volts and amps i have heard! Well done.
Wow, thanks! Keep watching us Ant.
Very smart video, relating it to water towers makes it very easy to understand!
