How to wire a distribution board with all loads protected by earth leakage circuit breaker -tutorial

Single phase wiring.
Example of all loads protected by earth leakage.
This is for a South African supply using the Samite rail.
This is a lab setup for the practical demonstration of wiring a distribution board with several loads - lights, geyser, and plugs. Loads protected by earth leakage with over current circuit breaker protection.
Further details found in the SANS 10142-1:2020 wiring standard - The Wiring of Premises Part1: low voltage installations.

Lot's of ways to actually save money with this DIY video. Well done Meneer 🙏

[kabandajamir]

The world's best teacher good explanation

[thammynthaly]

EXCELENT FANTASTIC demonstration. Wow the way you showed it was simple and clear. I also like the fact that you also mention how big the wires should be like the stove wiring or the lights etc. please kepp up the good work. that was very nice. thank you sir.

[leomajonileman]

Thank you sir the way you explain is very clear and demonstrations are very clear

[eagleeyes]

thank you so much Sir I learned an incredible amount. in the way you explained it is very easy to understand the special when you show fantastic done once again thank you

[shimmymaphutha]

Fantastic..well explained..made me wish I was an electrician

[mwc]

Very educational content, thank you. However I did not hear you mentioning amps for the stove circuit breaker.

[wistebaartokollo]

great explanation, thank you so much.

Hi good day. Please show a video of the static and induction meters and it's difference, we need a south African point of view, thanks for understanding

Can you make videos on troubleshooting

Brilliant Quick question, so if I want to connect half of the house's light switches on one breaker and the other half on another breaker i would have to twist 6 live wires of light switches together and connect that to one breaker for instance and another six to another breaker and the neutrals all gets connected to the neutral bar? Same goes for the plugs? Does that sound about right? Do you have a diagram or something that shows what amp breakers to use for what and what mm wires to use for each different section. I have posted another question on your Light switch replacement video of about two years ago as well. Thanks gain for this brilliant channel, best I have come across for us here in SA.

Great channel, great tutorials!
Question, I see my DB has Main Switch and Earth Leakage but you don't show a Main Switch in your connection. Is the Main Switch an optional switch?

[denzelm]

Good Day Awesome Video, Can you assist with my question . I have a 63 Amp main switch on my DB, I need to pull an AC feed to my Inverter, The inverter requires a 4mm AC Input cable (im using 6mm). In order to take the AC feed from the 63 Amp main switch, Can i first connect the power from the 63 Amp main switch to a 40 amp breaker using 16mm cable and then connect my 6mm cable to the 40amp breaker ?

[moeketsivictor]

Izt still okay if we put a single pole 63A to protect the earth leakage?

[arupghoshal]

I Went to check for UPS back up for our scanning electron microscope machine . That's why i was switched off the ups switch and connect multi meter across battery . At same time our elcb tripped, and machine off. And a burning smell came out from elcb. After that when I tried to elcb on with main power on. Elcb tripped automatically again and again . Can you please described the reasons behind that??? Is there any chance for machine burn? Please explain..

I the case of the lights not use 2.5mm2 wires and 20A CB, or is there a rule that 10A (1.5mm2) must be used?

[zekmsiska]

How do u connect a 16mm cable coming from a main panel Board

[abrammanoge]

Do you have CoC where are you located?

[rabidbunny]

Thank you, great tutorial.

Just a question with regards to circuit breakers / amp calculations.

When you have a main 63A breaker with a couple of breakers, example: 20A, 20A, 15A, 15A, 10A ... will the "amp" draw exceed the 63A supply if all circuits use close to their limits, or would the "amp" draw be no higher than the highest breaker in your panel?

Say I have a sub-db from a circuit breaker (25A), does this mean I should only have the sum of 25A breakers in my sub-db, or will the highest "amp" be used?

Technically my understanding is that since they are connected in parallel they will increase the "amp" draw by the sum of "sub-db" circuit breakers?

Or am I missing something here?

[kokotismorrison]

Not very professional installation. Active from earth leakage, can be connected from bottom, to the each circuit breakers after that, plus messy wiring.
