You will never go broke in Ghana, with such skill set and knowledge. You could set up a consultancy, at the same time a Tech College to train upcoming electricians, because you are a good teacher. Your content is unique, you've used your building project as a teachable moment for your subs. Thank you.
Wow, thanks very much
Thank you so much for being so generous with your information. I am in the US and I have been fortunate to do my DNA testing and it has connected me to my ancestral home of Sierra Leone. This information is necessary for most of West Africa. Thank you so much! 🙏🏾
I'm glued to your videos and taking all notes. See you soon in Ghana, my project manager is fired.
Very eye opening, thank you.
Just subscribed , but have been watching you guys for a while. Sorry for being late to the party 😁. I love you two and enjoy your energy. Your videos are very educational and informative!
Welcome to Asher and Gad
@@kingstal90 thank you !! ❤️
Well done boss 👏🏿👍🏿 these are question I was asking myself about, because I am looking to build and live somewhere in West Africa. I've got 26 years experience and always work in the UK. So my experience will help others to Install a good and safe installation.
Another great informative video. I see there are really levels to this internet and TH-cam content creations. Nobody out there is doing it quite like you. We are navigating this journey with you and Gad. Keep it up and more power to you
I appreciate that!
Thanks
Awesome video. Very impressive design. Will definitely checkout the ebook. Thanks much soulJah
Awesome
Have a blessed weekend
Hi there. Found your channel through Vanessa’s channel. Sending love from Florida.
Excellent presentation with detailed explanation. We carried out both 220v and 110v installation for a client a while back and detailed the process on our channel. Its quite frustrating for those in the USA when they come home and lack the option to connect their appliances without having multiple step down devices. Keep up the good work
Very good education. Thanks boss.
Most welcome
Thank you so much can,t wait for the diagram
Thats in the engineering ebook
In depth analysis. Very elaborate.
Well done.
Will definitely get in touch 👏🏾👏🏾👍🏿
Awesome, thank you!
feels good to watch ur videos,👍Top
Glad you like them!
Great job 👏. Looking good guys
Thanks 👍
This great to know all this👍🏽
Glad you think so!
Thank you very much for this video
You are welcome
Thanks and well presented 👍
My pleasure
I have not finished watching the video but I'm loving it already. 🙏🏽👍🏼
Hope you enjoy the rest when you continue the video.
@@kingstal90 I have watched it all mate and as usual, you never disappoint.👍🏼
Brilliant
Wow good job guys
Thanks
Was amongst one of the first people to comment on your first videos and still with you guys!!!
Was waiting on this video I have all the wires coming from the mains to my house and was just waiting to see how you did it. I understand what you have done so I will guide my electrician to do it.
Not had an electrician come to my house with a multimeter yet just an electric testing 10cedi screwdriver. This resulted in them spending hours on fault finding....what a hot mess🙆🏾
Great
I would love to hear an update once your electrical process is done.
This is great
Thanks very much
Wow 😲, I think I l’ll call you for help someday .
Impressive. At least I've learnt a thing or two. By the I am also an Electrical/Electronics Engineer - (Light Current/Telecommunications Major).
Good stuff
welcome to Asher and Gad
Good job
Thanks
You and your wife are amazing
Love this! You are focusing on the things most electricians overlook… I wonder if they have a national code book
They do, but many do not follow it
@@kingstal90surprised!! You should see what they did to my place
The concept is good however I remember you saying, you'll have to walk to the DB and manually/physically turn OFF breakers when you are on Solar. I think the ideal thing (and that is what i would have done) would have been for you to run all your essential loads (lights, fans etc) separately to a DB or consumer unit so you avoid turning OFF breakers manually. By doing this, you are using a breaker as a switch and the continual cycling (numerous ON and OFF) of it will affect the mechanical feature of the breaker and eventually lead to its failure. I guess it is not too late to re modify your wiring i.e if you buy my idea.
Contactors,timers and auxiliary contacts will be easier in doing the switching automatically than manual changing over all the time 🙏✌️
You might want to setup your electric installation company.
I can watch your videos only to hear you say "that's madness" 😅. Great content as always, keep it up
I appreciate that
Can and inverter solve the fluctuation issue or handle it? Or one has to install an AVR before the inverter setup. Because I was thinking of a setup with inverter and bms with the battery that will use the ECG as the energy source to charge the batteries to run the house even when the ECG cuts out /Sums of happens the batteries will keep the house going. But I don't want it to be setup on a separate change over as you would for a generator. What's is your opinion on this setup? Similar to yours but using 1 phase and batteries to serve as active and backup. Hence the energy constantly runs through the batteries recharging them while they are used.
Good video. Where can one buy the AC Automatic Voltage Regulator in Ghana?
I think you taking us back to the 1960s
Contactors
Timers
Auxiliary contact
Mcb
Auto flex cable 1mm2
16mm2
Panel box
This will solve the problems automatically than switching manually
Question bro. What didn't you do yourself seeing that you're well versed in that field
when you instll the generator you will have to get an automatic transfer switch and block out for the breaker pannel
Hi Gad, happy new year Bro and also to ur lovely Wife ,i returned to watch this video again today to see if i could found the E Book content list u spoked about during the last part of this video but unfortunately i couldn,t found any on ur channel pls kindly help explain to me where to find it ,Thank you
Happy New Year. read the Video Description. The link is in there
Hi Ash and Gad, Can you please send me a link to the South african architectural design website you mentioned in one of your video please.
Is the system well interlocked .. I fear there is the tendency of crushing the lines
Maybe u should do another video to demonstrate how interlocked the system is by switching L3 on while L1 or L2 is steel ON
The changeovers are in series, so it is impossible for two power sources to be on at the same time.
Great job. But what happens when you do not return one of the phase before switching to another phase.
I have seen a building with all three phase but the change over is just for ECG/generator
Thats a simple changeover
You cannot understand the full detail without the engineering drawing/schematic and wiring details
You don't have to return the switches.
for example if the building is on L1, I can simply switch to L3. Obviously there will be a power cut for the small transfer time. You cannot do anything about that be it a manual or automatic system.
How many Ams per each of your (change over ) ?I need a good electrician
you need to open a company for this , so that some of us can contate u.
Sure. But you can email: ashergad21@gmail.com
any reason why when you were cycling through the phase's you didnt leave the ones not being used in the middle position(green marker on the changeover box)? i noticed you always put them to the far right except the changeover that had phase 1 & 2...which was placed in the middle. Also why did you isolate the solar and generator on separate changeover boxes? Could you have wired(grouped) it the same way you did the phase 1 & 2 changeover?
Thanks for your comment. You cannot fully understand without studying the electrical drawings/schematic.
For example when the system is on L3, the position of the first changeover is irrelevant as the output is isolated. regards
How much did it cost to put the whole system up?
I think you can setup some SCADA system or control units to be doing the switching/change over automatically, right?
It can be done automatically as stated in the video
But your cost will be at least x6
@@kingstal90 I understood. So having a programmable control units for this is really not advisable for domestic use you think. So would there not be a reasonable prized control unit for this application at all?
What's the " AMPS" of your change over and TPN ?
I have ( 6 a/c , 9 ceiling fans, 6 water heater, 2 freezers, 2 water pumps , 1 bore hole pump ,
I will have 2 Changer overs
.......................
Solar
Generator
How can I contact u, my wife and I are interested in moving to Ghana very soon and would appreciate any assistance
Can you still have all these faces done if you already done with your wiring and there is light in the house if so kindly advise
Sure. Alterations can always be made. However, it depends largely on how much space you have in your electrical room. The system can be installed by simply breaking into the circuit between the TPN incomer and your distribution board.

Link: payhip.com/b/BlyQ9
so please how much is the ebook
Please what is the name of the consumer unit
Does ECG provide a single 3-phase meters?
Or by 3-phase meter you mean 3 separate 1-phase meter?
ECG in Cape Coast just told me they only provide single-phase meters. So I don't know how to go around it
Don't understand that, sorry. There are single phase and three phase meters. Unless why would their website have prices for both? - I know many who have 3phase meters
So you meter from ECG is 3 phase. What about the accuracy of a 3 phase meter receiving single supply at any time
No issues
I like your ideas but for normal residential buildings I'm in the views that is somehow not really necessary however, for industrial purposes, it can be applied..
Again, manual changeover switch is a heck, why not automatic changeover?
Because automatic system cost 6times more ! and requires alot more co-ordination and settings. This is a choice for the home owner. Manual is absolutely fine for us
Also I want to ask it your system is idiot proof? The question is what will happen when someone changes or turns on L3 whiles you still have the L2 or L1 still on or active? Will they cut off automatically ?
if you change to L3, the house is powered via L3 simple
L1 and L2 will be isolated from the house
@@kingstal90 I have the same question in mind since you didnot address that in your presentation. Also, couldn't you have just one isolator thr toggles among the 3 phases, with only 1 phase active at a time. Another thing is that, the house is increasingly becoming and electrical plant 😆 and trust me many times are coming when your house hold would be like, "let's wait for engineer to comw deal with his toys, for this is too much for us to handle"😒😃🤣😃🤣
@@kingstal90 I noticed you had L1 and L2 on one box and L3 on the other. What I meant by it being foolproof is, what happens when L2 is actively running and the person turns on the switch over for L3 to be active the same time without isolating or turning the switch over for L2 to the off or neutral (middle position not sure what you call it). Because the L2 is already supplying the energy from one phase and you turn on another additional phase with duplicate energy coming into the same supply unit, wouldn't this cause an overload or blow any fuses? Or you have an inbuilt relay that diverts the power in the design that prevents two phases running at the same time?
Distribution board must be big enough to handle all the circuits…..👍🏿👍🏿👍🏿👍🏿
Yes it is
Hi Gad, in the UK live in Crayford
I would love to meet you to show you my project I need a work to be
Can you please plan my project full wiring for me please- the project is in Ghana but I reside here in the UK
Not at the moment. maybe in 4months time. We are not consulting yet
@@kingstal90 i will love that too
Bonjour Ashgad.. Kingsley I need your help I'm building a 6 bed room house, phase one of electricity is done its left with two and final..but right now I need you
Thanks for your comment. I am overloaded at the moment. Sorry
@@kingstal90 thanks for your reply but can you please recommend a trust one for me,..i got in touch with someone who one of youbes recommended he charge me 45,500gh for laying on pipes..,i thank him and say bye bye to him
Can you use only Solar Panels?
Of course. There are off-grid systems
How could u do all these? For a layman like me, how would I know when something is not done well
Thats why you employ professionals. Professional designers, good electricians and good project managers/builders
It seems you know alot about project. are you a electrician or project manager? Anyway that's awesome for some of us that has just started our projects
How can we get your electricians contact information?
The way I am seeing it is that surly one can pay you a small fee to implement all of these things depending on the size of the house I will have to come and seek you out when I am in Ghana for yr help because I don't think those in Ghana are advance as you
total agree with u, was thinking same as well
Engineering doesn't work like that am afraid
Every project is different
different setup
different spatial requirements and constraints
@@kingstal90 every home is different yes I totally agree with you on this but if I am mistaken then please correct me if I am wrong from yr setup why can't a pre design be possible of the electric lights and out let's and the total Voltage that will be needed or have I got my wires Crossed here ??
Nice idea to distribute the 3 phase to your house but the change over system is not safe. For me it is better for the L1 and L2 be installed in one unit box. If power goes OFF on LI and comes ON at L2, there is tendency that someone may forget to put L1 OFF and directly put L2 ON. If later there is power supply again on L1. In that situation both L1 and L2 will be having current and supplying to the same fuse box. What will happen to that fuse box and the entire installations of the house.
A change over that is controled by the same switching unit, no 2 or 3 phase will never supply your fuse at the same time to cause damages
You haven't understood it properly. You cannot have L1 and L2 supplying the load at the same time. Its one or the other.
It is very safe !
Only one source supplies the load at any time (either L1, L2, L3, generator or solar). Only one source.
There is nothing like supplying the fuse box by two phases at the same time in this installation. Thats why its a changeover (manual transfer switch), source 1 or source 2 to the output, not both. Source 1 and 2 of any changeover are mechanically interlocked! - That is how it is manufactured (with safety in mind), so the situation you describe does not exist.
@@kingstal90 not supplying the fuse box
@@kingstal90 since the changer overs are in different switch boxes, there is possibility that someone may forget to switch LI OFF before switching L2 ON. Remember power has gone OFF on L1 but it is still on the ON state and then you put L2 ON. Now both L1 and L2 are on the ON state since the person has forgotten to put L1 OFF. If later power again from your meter to L1, it will flow directly to your fuse box since the person has forgotten to L1 OFF. Now both L1 and L2 are having power and supplying same fuse box. So what do you think is going to happen ?
Now power has come back to L1 and the person has forgotten to put it OFF. At the same time L2 was already supplying .
@@kingstal90 In Europe L1 and L2 are installed on the same switch. In that case L1 and L2 will never be put on at the same time by mistake
Your changer overs L1 and L2, are they not on different switches/boxes ?
Why did you separate the PV from the grid. You can use the PV and grid power simultaneously with an inverter that has zero export capability. So that you don't use too much of power from the grid in the afternoon when the sun is up.
Yes I know. Off grid or grid-tie is a choice.
Hello Gad how are u doing ,Gad can u coming to Kumasi to help me with my please reply thanks
Sorry not possible right now
You have a lot of questions to answer because there's a lot of disadvantage in this type of set up especially in the normal residential house while there's a simple way to go about it the costumers will end up calling their electrician to come and switch to other phase for them because a little mistake they can switch 2 or 3 phase together and the house will catch fire,we normally use this setup for industry works and more over you were talking about saving money how can you save money by buying 4 change overs 1tpn and consumer unit , and you also didn't talk about the disadvantages you just went on sweet words like that
What happens when you mistakenly turn two phases on at the same time?
Its not possible !
Transfer switches are break before make / mechanically interlocked devices.
You have two inputs to an MTS .Only one is connected to the output at any one time
the inputs are mechanically interlocked
Even if you turned two switches at the same time (which is physically challenging - on purpose) as one phase connects the other is disconnected. You may not understand if you are not a detailed electrical designer. The MTS also have safety contactors within them.
@@kingstal90 so the switches, you have three of them. Let's say you turn on the first switch on (phase 1) but you forgot to turn it off again before switching to phase two. You end up with both two separate switches turned on. That's what I I'm asking if it'll cause a collision. Unless there's a safety mechanisms.
My way of thinking is to split between phase one and two (output being either 1 or 2... let's call that Z1)and then have another to split between either Z1 and phase 3. Will that also work?
@@aberba - As I say, with respect, you are not an electrical designer, so difficult to understand the exact details. It is NOT possible to collide the phases. You don't have to turn off phase 1 after you turn it on. That does not matter. The system is proven and safe and installed even commercially. Phase 1 switch can be on, no issues. If I turn to phase 3 on the second MTS. the phase 1 output is automatically DISCONNECTED !!
@@kingstal90 okay I hear you. That makes sense.
I'm asking because I intend to do the exact same thing.
But I would like your opinion, what about the alternative approach I talked about above?
I think I know why, but not too sure
Simple answers:
1. I have other full time commitments and do not have the time to do it.
2. There is also a difference between a Consultant, Electrical Design Engineer and an actual Electrician. The two are not necessarily the same.
3. Personal choice and building programme implications
@@kingstal90 that's what I thought. As well as the your labor value. I'm sure you know what I mean.

Thanks for your comment
Absolutely! - This is engineering and its not cheap. I asked other companies to design for me as a comparison and was quoted 750USD minimum just for the intake room. So mine is much cheaper.
There have already been a number of purchases.
All the best.
Gosh this must be overkill
The components of a fridge needs to be changed so that they can run on the minimum amount of electricity especially when there is solar power I Know that this not what you are discussing but as to do with power I am speaking of this
Hmmn can you explain this a little more?
@@ladysaw9995 depending on the power whether you are using 230/ or 240 power the compressor that compress the gas draws a lot of amps when it needs to which I believe/ not sure make it difficult to use solar panels / believe/ not sure that the compressor on a fridge / freezer can be reduced to do so I am not an expert in electrical components but from a mere mortal I believe that it can be redesigned to do so especially when it comes to been used in very hot climates, and since the enforces is on using less energy and to use less materials the technology is here already at least a thousand years in advance
