Why jumper links should not be used on distribution boards across circuit breakers

[@AfriHubGlobal]

Gooday we've been having problems since we moved in a few weeks ago. Still our Stove is not working, thank you I learned about a Bus Bar from your video.

[@paulnyirenda6690]

Wow, my BEST PROFESSOR on electrical explanation. Keep the good work!

[@raydelrativo1409]

Beautiful. Been looking for a video explaining this in detail for about 2 days

[@logiclondon5727]

Same spainuses jumpers

[@elishatech4600]

Finally I have found what I was looking for

[@marinetrax]

Hi, thanks for that. Where does the neutral and earth go in this set up? The wires go out the bottom of the box. Do they both attach together at the ground stake? Thanks

[@africanhistory]

Did you do a video on wiring an inverter into the db board for only some plugs in the house (with a low load).?

[@mrtechie6810]

Terrible idea to have two feeds to the same electric panel. That is confusing, non-standard, and a huge safety hazard for all! The inverter should have its own separate electric box/panel.

[@xbullshet]

Super simple and easy to understand! Thank You.

[@barnesn8963]

In just 5mins I learnt alot, thank you

[@kr.abhilash]

I actually have a query. I'd be thankful if you could help me out. i have purchased a 8 way tpn mcb box. however on all 3 phase loads, only 6 are occupied by mcbs. But the busbar link which came with the packaging has 8 positions. so how should I isolate the remaining two links.?

[@jiqana]

what about the Terminals on the circuit breakers, how many amps can they usually hold?

[@MotherRussiaisforever]

Well done, what is the hourly pay for electrician in south africa? Including maintanence Engineers...

[@waltlarson487]

Where can I buy the busbar for the mini circuit breaker box?

[@Ishmaellllllllllllll]

Can you jumper from L1 to L2 to check if there’s an error on L2 cause of a voltage drop coming to L2.

[@myoz6804]

You are an Awesome teacher!

[@giovanninongbri2250]

What if I use a wire that can carry 63 amps and jump to all the other breakers?

[@elmultimediaschoolofartscu3924]

Do I contact you Sir? I am in Pretoria

[@InnochellyNyengerah]

A vivid explanation

[@carlossantini]

Very helpful. Do you have a video on how to install a double throw switch to bypass an inverter to supply the loads from the grid?

[@travismailsa1]

Both inputs into the bottom, one being mains, one being inverter supply, then top is output of either inverter at bottom, bypass middle and grid up/top

[@travismailsa1]

If you like i can send you a picture

[@carlossantini]

@@travismailsa1 yes

[@elmultimediaschoolofartscu3924]

You are my new teacher 😅😮

[@fa63]

Hi, you put a jumper cable that can carry 10amps from circuit breaker 3 to circuit breaker 4. So, circuit breaker 4 is rated at 10amps which is fine for that jumper cable to handle. But isn't that jumper cable a fire hazard if circuit breaker 3 is also pulling 10amps. Should that jumper cable not be rated to carry 20amps if both breaker 3 and breaker 4 pulls 10amps = 20amp.

[@durragas4671]

No, the 10A jumper cable creates a closed circuit over circuit breaker 4 only. CB 3 can function with or without that 10A jumper which tells you it's not needed for CB3. But just using 4mm cable for jumpers should solve this because that handles 64A just fine.

[@odinnln5694]

Even with a busbar the higest rated MCBs should be closest to the main switch in descending order.

[@mrtechie6810]

Could you talk about endcaps and insulation on the busbar?

[@BarryMaitlandStuart]

I love these videos, thank you

[@mrtechie6810]

What if the panel has various brands of MCBs that have different heights -- so the busbar won't reach the shorter ones?

[@superpooper_2030]

You should buy the same size (same width & height) to avoid loose connection of busbar. I have 4 different brands but with same size in same row

[@superpooper_2030]

If you are worried about future add-ons, always buy extra few MCB and install together with busbar. That's what I am doing

[@dormstories]

The wires going in the 63A circuit breaker are the same section as the one going to the individual breakers, neither can hold 63A, so the main breaker needs to be changed first of all!

[@johannesmahloele2385]

How can 1 secket braiker if is over loaded switch it's self let's say 32 amps for stove not dropping earth likege

[@ManofCulture]

It looks much cleaner too

[@jvanniekerk1]

Brilliant video thanks

[@JamusMigo-tk4mk]

Thanks u very much big boss

[@lucapuzzoli8363]

3:13 the RCD will not trip for overload. It will triped if residual current find a path to earth .

[@ExcelTimeSavers]

Lovely

[@costadhimbo1364]

Very informative

[@dominicalbano8459]

I think the jumper conductors should have a size or diameter similar to the main feeder conductor.

[@robbrown6495]

When I see videos like this I often think that, while they contain good information, if inexperienced DIYers don't know this stuff they really shouldn't be working on their house wiring. Yes the video teaches useful information but what about the thousand other things it doesn't teach, that experience and training have taught, that could end up causing a house fire or electrocuting someone?

[@93lornamae]

Thats a rcd. Not overcurrent or short circuit protection.

[@pg8605]

The problem is that busbar are not available always

[@persuademubayi9363]

That is sound

[@tinnedanger]

Common sense says you use a larger "jumper" for each breaker. Same as the feed wire. not rocket science.

[@mrtechie6810]

Common sense is uncommon.

[@pricey4566]

Well it is actually science a 16mm cable underground is rated at 80 amps and overhead is rated to 63 amps due to length of run and derating due to heat in a switchboard a 4mm cable could actually be rated at 80 amps and easier to work with

[@geniusmarcsays2434]

4 mm jumper links

[@geniusmarcsays2434]

hahaha if you need to retighten after few days, you did not tight it hard enough in the first place. i have done work that lasted years ... train your grip

[@ecologicaltime]

if you go to many DB you can see that even when the screws were initially very tight at first, some loosen. The copper strands compress over time and that's why i re tighten.

[@geniusmarcsays2434]

@@ecologicaltime i am an electrician, and if i have to go back after 2 days to each customer... it's a bad situation

Crimped connections are better.
