You are doing an amazing work. I can see how passionate you are and willing to share your knowledge with us, and educating us. I don't know what to say anymore. I do appreciate you and auntie Crystal. May Yahuah bless the works of your hands!!!! I can't wait to learn more from you. Peace and blessings 🌺🌸
Hello, excellent presentation and vid. I can relate. My first electrician (a relative) installed Ro2v4x10mm2 from the meter to a junction box and then run 6mm2 to 2 different boxes of circuit breakers downstairs and upstairs. He had to go!!! The new electrician recommended Ro2v4x16mm2. I overruled him. Now we have Ro2v4x25mm2 running from the meter to each of the circuit breaker boxes. Watching this vid has reassured me that we are on the right path. Tfs!
Another great informative video. Now I'm going to have to check with my project manager to double check every thing with my apartment since Im not down there. Thanks a bunch. You guys are doing all of us great service. Keep em coming
Glad it was helpful! However, remember it depends on your exact load assessment / method of cabling installation, etc. An apartment complex is much bigger than my house. I dont know how big your area is or how many rooms you have but assuming it will be much bigger than my home. Bless
@@kingstal90 You are absolutely right. Which is why I needs to talk with my PM to assess the situation. Its not a huge project. Its only a 2 bedroom 6 unit complex. I remembered paying for the 16m cables. Thank you.
Thanks for sharing your insight. As an engineer myself, I enjoy doing these calculations for basically everything but am not so good explaining this to others l like you do. Great content. You will be the best person to consult for my Net Zero 500 SF tiny home I intend to build in Ghana.
this is what they have been using for most homes in Ghana and I believe this is why most homes are running on low current. No wonder a lot of people are using getting home fires because that 10mm would heat up and there would be high resistance caused and this would have your metre reading higher and it will cost you more. I think they do that deliberately to have the metre reading higher to run your credit out. Because this is the cable 10mm they have been using for most people instead of 16mm atleast. Thanks for this knowledge. Because we have this problem at home and we experience a lot of low current and higher meter reading making the prepaid metre drain a lot of credits. I think they lied about the cable being temporary because they didn't know you would find out and when you did. They had to convince you that was temporary because they know you know what you are talking about and they cannot B.S. you. Thanks very much. Really helpful.
@@kingstal90 This is why there a lot of cases of homes catching fires during voltage fluctuation or when the power is turned on after a blackout. They didn't mean to do it temporarily, but when you caught them they realised they can't pie to you. Make sure you don't have to pay them to correct their mistake. Those guys are mostly technicians and some are also in experienced and with gross negligence and the real engineers that are supposed to supervise their job sits in the office and boss them around whilst these guys that are on the field are underpaid, unlike them so not much motivation on the job.
@@nanabrimpong3485 - The voltage fluctuations are ridiculous in parts of the country. I'm surprised this hasn't been sorted out properly yet. Even in the expensive estates- still quite a bit of fluctuation in the power supply from ECG. its a shame. People need to invest in an AVR.
Great information as per usual. Great suggestion regarding the solar power system only running a few appliances during power outages as most people suggest running the whole house which is mega expensive. I can now see a much cheaper option that can be upgraded at a later stage as costs and technologies improve. Now u see why i never miss an update from u guys. Well done and thanks again
When it comes to electrifying a house or even building one, we are at the mercy of unscrupulous people who exploit the ignorance of say first time house owners looking to build a homestead. The question is does the building trade have published standards on all type of builds, with specific references to parts of a building. Your expose’ has been useful and reassuring but what happens with dealings with a builder at Domeabra?
Great video. loved every bit. I install Solar systems and I always advise my clients to get a set up to run only the essentials like you said, ventilation (fans) , lighting and some light loads. This give you the opportunity to reduces the time to realize your ROI, the system(especially the batteries) last longer and you get to improve your power reliability at a low cost. It's good you got the solar thermal too. Using the grid (ECG) for heating is also very expensive. So far I will say Kudos! You have a very solid energy plan been executed excellently.
OK really, That's great and very good to know. Have you watched our video on "Cost of Solar Panels in Ghana"? They are so expensive around the 10kW mark and upwards.
@@kingstal90 Yes I have. In actual fact the grid (ECG) is far cheaper than a kWh of electricity produced by Solar power in Ghana because we mostly install off grid systems with battery backup which is capital intensive. I still use the grid and still benefit from my lifeline subsidies which makes ECG cheaper but run my solar for reliability which the ECG lacks at very critical times of the day and seasons (during rain just be on stand-by for a blackout and in bad neighborhoods with power issues a brownout when they start increasing power consumption). Like I said earlier you have one of the best energy plans for your home I have seen so far and i hope many of your subscribers model it. Getting the generator to power heavy loads is also in the right direction like you are doing. I guess being an engineer you have already worked out the right energy mix (Grid + Gen+ Solar thermal + PV Solar ) and I very much agree with you.
I totally agree. I aim one day to do the same. Jamaica public service JPS are a rip off, so I want to go off grid when my time comes to build and migrate. I'll need Asher to help me design a very similar system. I'll effectively going to be off grid but the system I need will be huge. Around £20-24k. I'm scared.
On the lighter side @ 10:03 your reaction to ECG was really funny. LOL. They are trying but we still got a long way to go. ECG can be a nightmare you least expected to deal with in your life.
That electric has to be right. Good catch on that. The average homeowner would not have thought to look at that. It’s too tricky trying to build. Why is the trip set For 100 and would not have tripped in time for the wiring? That would have passed inspection?
Don't clearly understand your question. The 100A MCCB is installed by ECG and not me. They install 100A as a max because their meter is typically 100A rated also. Its purpose is mainly to protect the meter itself

Great content once again. I have one question though. Why did you use a 100Amp circuit breaker if your total current is going to be under 50Amps. I know you needed to make some room for contingency, but why did you go all the way to a 100A🤔
Very informative as usual. But are your rooms not going to be very hot with the concrete roofing instead of the conventional metal or aluminium roofing sheets?
In the U.S. MOST electrical boxes are inside the houses. I would like to know why the houses and buildings (malls, stores, churches,etc.) are constructed with cement and not wood in Africa? If you know the answer please let me know. I watch your videos because you teach and illustrate very simply to where anyone paying attention will understand. 😊
Hahah, very interesting question we build our houses like that because of weather and also to resist and weather conditions, most people can't afford the air conditioning system so with our system of building, the room turn to be cooler even if you don't have the a/c system, that's my two cents
The reason(s) notwithstanding, building with concrete is better than wood. I own two houses in Ghana and a house in West Orange, New Jersey. The houses in the States appear to be so cheaply constructed with wood, dry wall and prefabricated materials. No wonder these houses crumble like cookies when there are floods, tornadoes, hurricanes and fires.
Hi Chris & Asher Good content as usual. I recall watching one of the videos and you showed us your electricity current stabiliser. Can you please let me know the details of the stabiliser, the cost and where you bought it. Thanks Dan
LOL You don’t understand my installation First to clear up your dividing by 3 statement. If I have a load of 80A and I want to support that load using single phase, then that single phase cable will need to be able to safely deliver 80A If I want to support the 80A load using three phase cables (3 live + neutral) then in that scenario, each of the cables will conduct 80A/3 MY HOUSE Assume I need 80A I have 3phases coming into the house. BUT my house only uses single phase!! Only 1 out of the three phases supports my house at anytime via the changeovers. I have connected 3phases simply to make the installation more resilient. In this case I need each of the three cables coming in, to be able to supply 80A. If my house is on L1 it gets 80A if on L2 80A and if on L3 also we get 80A. Each of the cables must be at least 16mm in order to supply the 80A If you’re not an electrical engineer or have not seen the schematic details then you may not fully understand. My house uses single phase only So one phase out of the 3 coming in will supply electricity to the house! The 3phases coming in is for resilience purposes ONLY. If there’s a problem with L1, I switch to L2, and so on/ so forth I will demonstrate the switching in a later video with more details of the changeover system in a detailed electrical Ebook Bless
@@kingstal90 Thanks for the explanation and I now see your point. You're using a single phase and that make sense to use 16mm cables. My house was designed differently with 3 phases shared among the entire house. Two of phases supply power to ground and first floor whiles the third phase supply power to 20000 Watts transformer to convert 240V to 120V for my USA appliances so I have both 240V and 110V within my house. The ground floor lights are 110V whiles the first floor uses 240V so my is completely different. It was designed by my friend here in US. Thanks again bro. I will look for you I come to Ghana in two weeks God willing 🙏
@@davidgyimah4377 Thanks for sharing. I'm also considering similar setup for my home. I'm also based in the US. I'd appreciate the opportunity to connect with you --if it's okay with you. Thanks
what is the max surge? In the US the max surge is 225a, the cable is size 0000. Here in the US, the meter is the main that the consumer cannot touch the disconnect is after it. Question due residents there do duck banks, the power coming from the pole to the conduit in the ground, power is coming up. Is that a common practice there?
Formally,main cables were permitted to be hidden,but because of rampant stealing of power, electrical contractors were ordered to display it open.hence the trunk.
@@danielneequaye5505 Is it a requirement in Ghana? Cus first of all it looks ugly and dangerous when exposed. Second, some real estate developers bury their cables. Also done in major GH cities buildings. It'll be very primitive to enforce this kind of wiring when the rest of the world is moving ahead. Nevertheless, it doesn't look good. Those plastic trunking will come off in no time...their quality is meh.
@@danielneequaye5505 I don't know about that, because I don't have any truncated stuff on the wall of my recently completed dream house. It's an eyesore. Hopefully, it's temporary. Having the distribution board on the wall of the main house is not the best. I have it on the wall of my staff quarters structure and it's concealed in a nice wooden enclosure with a cover built by my Carpenter.
Hey Guys Thank you very much, You are impacting some valuable knowledge to us. I also just bought 3 of your ebooks. My question on this cables is, what are the disadvantages of installing a bigger size cable instead of exact size, Lets say a 2bdr house with a 24amp and you deciced to install a 16mm2 cable? Hope to hear from you. Y3 B3 Shia.
Thanks for the update but for the past three weeks now I have been asking you a question and you have ignored all my questions. Please help a sister out , once again why did not choose cement blocks over bricks in building your house? I am asking because of the longevity of bricks over cement blocks in long term history has shown as that bricks last thousands of years over cement blocks.Thank you
Thanks for the video. Does the ebook contain the details on the ECG Phase changer I enquired about the other day? Also what’s your take on underground cable power (ECG) supply to a house?
What ECG Phase changer? There is No ECG Phase changer Underground cable is fine. it is more aesthetically pleasing. Just make sure it is the correct size as this installation method is very different and has different design factors to be considered when cable is buried in duct/pipe in the hot ground.
@@obiaw204 - No, that will be a separate video and ebook entirely. In the video I will demonstrate the operation of the changeover and the AVR and include all details in the ebook
A big thanks for your info! Please how much is the main electricity voltage in Ghana and also can you use domotica electricit system in Ghana? I don’t know if you know of Domotica system!
@@kingstal90 all Description Home automation or domotics is building automation for a home, called a smart home or smart house. A home automation system will monitor and/or control home attributes such as lighting, climate, entertainment systems, and appliances. It may also include home security such as access control and alarm systems
@@Boateng1979 - ok great. Yes very aware of home automation, just hadn't heard about the manufacturer Domotics. Thanks very much. Personally I actually don't want too much automation due to risk of hacking, etc. Just a little bit is ok for me
Kingsley, perhaps you need to look at putting a smaller AVR at the interface between the meter and ECG for 10m2 cable or change it all together or do both. I know there is a breaker but a friends house caught fire although he had some some sort of AVR inside the house it didn't prevent the surge at the meter point as you would expect. As I don't have the full details of root cause of the fire, he seemed to suggest and as well told by ECG and fire service that the fire was due to a voltage flactuation a the meter point. Can you illucidate on what your thought are on this. Thanks Akora
The cables are no longer 10mm2. We changed them to 16mm2. Very strange and difficult to say without a proper root cause analysis. There could be many reasons. Trust all is well with you
This is an amusing comment. You want my engineering information for free? Sorry - That doesn't happen anywhere By all means - If you can get an engineering design from somewhere else for free please go ahead. Also please note, you don't have to do anything. It is NOT compulsory to get the ebook. Time and intellectual property is MONEY!! Those who need it, get it and many have already. Have a good day.
