FINALY thank you I am needing to rewire my house and have been struggling to find out the best practice for South Africa THANK YOU for this information it is life saving seriously though i cant say thank you enough.
Thank you Jean B, Your videos are great, please can you make a video on how to wire all the lights and plug points in a house it would be greatly appreciated.
Hey. It's so easy to understand in the way that u explain it. Tx for a real well presented video. Can u do a video on how the wiring is for DB's for solar systems splitting the essential and non-essential loads, please?
Great stuff man. love the video. Really good explanation. Thank you - Can you please do an inverter connection on DB board. I am sure you will get lots of hits on that one;) Have a good one nice to see more south african videos on RU-vid.
Just a small thing ,I would have liked you to fit the buss bar to the top and around the neutral wire to complete the circuit ,Thanks Great information.
Hey Jean, great video.... I have a small 600w pure sine wave inverter/ups with a plug outlet that I want to connect to my light circuit (1 x 10a). Is it possible to wire something like that to the light circuit legally here in South Africa and what other things do i need to take into consideration.... I have a 2 pole 40a din change over switch that I want to use...... perhaps a topic for your next video?
Hi Jean. Thanks for the video. Quick question, should your SUB DB's be connected on the MAIN DB E/L or not? All my SUB DB's do have their own E/L's installed.
Hi Jean, Thank you for putting up videos for South African installations. Just a question on the Water heater circuit. I see that you use a single phase CB for the water heater. How does this installation fit in with SANS 10142-1:2017 Edition 2 Section 6.16.7 Electrode water heaters, steam generators and boilers, where it is stipulated to have the water heater supplied from a multipole circuit-breaker?
Hi Hubert. The single pole breaker is sufficient if you have a double pole isolator within arms reach of the water heater according to the Western Province Inspection Board (Aug 2020). In regards with the water heater on earth leakage, that has changed sometime last year I think. New installations of water heaters need to be on an earth leakage. Thanks for the comments!
This is easy. The bit I’m interested in is how electricians can upgrade the entire switchboard, including putting the main switch, when this switch still gets power from a meter. Asking because there is no means to shut down electricity simply because the main switch is also changed
Hi Elena. To switch off the mains you will have to contact the electricity provider. Around here they come out pretty quick and dont charge for the service. Changing a main switch with the power on is not advisable. I had to do it one or twice in situations where switching off the power was not an option. Insulated tools and gloves is advised in a situation like that.
Great Vid. Thanks I take it that an Ac Air conditioner is also wired as a stove geyser lights cct via the Main buzz bar for neutrals and the live feed only from the Main switch?
Great vid, thank you! I'd like to get in an electrician to connect my Ellies 1440w inverter kit with 2 batteries connected directly to my distribution board. Is there a limit to the number of breakers I can connect to it?? In my case I need 2 which are crucial and as a bonus another 2 or 3 (lights and plugs - no geysers, stove or fridges).
Hi Boutit To my knowledge, the only limit is the watts that you have. (1440w) Circuits are up to you. Just remember to put in another earth leakage after the inverter so that it will still protect you in case of trouble.
Hi. Yes,they must be fed via the shortest point which in the general breakers are from the top. Im sure you can order breakers that are fed from the bottom but not the normal,everyday breakers. They will work fine if fed from the bottom but the law states the shortest contact sould be live.
To a light switch you will run a LIVE wire down to the switch and a RETURN wire up from the switch to the light and a earth wire of coarse. If you don't do a connection in the roof you come down to one plug and up the wall to another and so on.
Hi Ashraf. No,the wires size and the breaker size are matched to protect the wires. You can add lights and sockets as you like until the breaker trips because of too much amps. In South Africa the law recommends 7 socket points per circuit. (If the law is still the same) but it does not set a fixed limit. But try and keep it around 7 points. (Can be 7 double plug points) When putting in new wires always match the size off the existing wires. It is always good to check if the breakers and wires are matched as well.
Hi Ashraf. If by radial circuit you mean goes from the breaker to plug number one and jumps to number two,then three and so on,then yes it can be radial. Just be aware of the amps as it adds up faster if you have high power items plugged into the three phase sockets. If you mean just the busbar feeding the breakers then check that the busbar can handle all the amps as well as the wires feeding the busbar is rated high enough for all the amps.
To my knowledge, the old DBs were wired with supply from the bottom. The law states that the Live part sould be the "shortest or smallest" conductive part. If tge breaker is designed for the live to be at the bottom its fine. But if its not, it should be changed. That is as far as I can remember, you could always just call the inspection board.
Hi Ashraf. I did a few years working as an apprentice. After that I went to ECA yes. That was in Woodstock if I remember correctly. Was 10years + ago though!
@@p0we111 students usually go to ECA for training before starting apprenticeship. But Schneider electric also gives 2 day training on installation and fault finding. We basically just need some basic knowledge before you start working
Hi Ashraf. If I were you,I would read/memorize the SANS 10142 Wiring Code book before anything else. You should be able to get it at ECA or the Western Cape Approved Electrical Inspection Authority.
Hi. It depends on the current law in your country. The laws in South Africa has changed a great deal since this video was published. It used to be only plugs must be on earth leakage. You can put all if you want but its not necessary. Today if a stove has no stove coupler the it has to be on earth leakage. If a ceiling fan is not on an isolator switch then it must be on earth leakage. Geysers/hot water cylinders is a must for earth leakage today if Im not mistaken. So basically if you put everything on the earth leakage you will be save but can have a lot of nuisance tripping 🙂
Hi Eddie. Not sure what you mean. The earth and neutral can only be joint at the place where the power first comes in on the property, after that nowhere else.
Hi Ashraf. I'm not sure about the difference between them. You would have to decide for yourself. Just make sure that the one you choose is accredited and will be recognized by companies as a legit qualification.
@@p0we111 both the college and Schneider electric practical training isn’t accredited. But Schneider electric is the manufacturers of the products which is better getting training from them. Maybe it’s good doing the course just for knowledge that can help with your Apprenticeship. I’m completing the N3 Electrical certificate. Just need some practical training
@@ashrafkarjiker6888 Do as many courses as you can if it is an option. I did the Siemans plc training and it was eye opening to see all the new technology I did not even know about at that time.. That was 12years ago though! If you can,do it!
Hi Xavier. A double pole CBi is only necessary if you dont use a isolator within arms reach of the geyser. If you want to use a double pole instead of a isolator at the geyser the CBi doubke pole has to be lockable. To wire just take a live and neutral to the top of the breaker and the live and neutral going to the geyser at thr bottom.
Hey jean b I would like to know I want to add a light switch to my exciting lights but I don't want to go in to the roof can I wire it to the DB board If so how can I do it
Hi. Yes you can wire a new light circuit into your DB board. You will have to use the same size wire and the correct type. Check where the existing light circuit is. The live would be connected in one of the circuit breakers. The neutral should be on a neutral bar and the earth on an earth bar. Just connect your wires in the same places. Be careful and switch off all power. If you are not sure get an electrician!
How do you wire from the meter to the double pole switch without turning off electricity? i mean what is the best practice for safety since there are no switch to turn off between that and how do you strip the wire insulator while the electricity is on? Sorry i am a novice need to ask you for guidance
Hi. I always contacted the electrical supplier to switch off the electricity. You cannot open the meter with the electricity on,as this will trigger a safety cutoff and you would have to contact them anyway to switch it on. As for stripping,get yourself a good quality 1000v rated pliers. You can also get insulated gloves.
Half of the circuit on my outside lights aren’t working. Do they connect at a junction box. Each light fitting just has one set of cables. How do you find the junction box for that circuit. There’s no voltage present
Hi Ashraf. Yes,if only one set of wires run to a light fitting a junction box is present. You will have to trace the wires from the light hopefully to a roof space\crawl space. They can also all be run to the light switch,but that is unlikely. It is illegal to put a junction box in a place where you cannot access it,but that does not stop some people still doing it.
Hi Ashraf. In South Africa we have the Wiring Code (SANS) book. It is a government issued book. You can contact ECA (Electrical Contractors Association) or WCAEIA (The Western Cape Approved Electrical Inspection Authority). I'm sure there are others,but these are the ones that I remenber. I'm not sure but I think a online version is also available.
How can one do his own electrical wiring at home and get it approved. Those that’s qualified can just teach and inspect whether the DIY Projects are done Correctly
Hi Ashraf. I believe if you want your work (diy) sighed off,you will have to wire it under the supervision of a qualified electrician. Then someone can sign off on your work. That is how I worked as an apprentice,before qualifying.
There’s to much studying involved becoming a qualified Electrician so I’m only interested in learning the necessary information from experienced persons to get the job
Het jy Facebook? Sal jou graag wil kontak. Jy het my aansienlik baie gehelp! My stoof se neutral was heeltyd gekoppel aan die EL maar sy live is voor die EL gekoppel. So ek kon nie uitmaak hoekom my oond die EL trip nie maar jou video het gehelp! Hou so aan my vriend!
