EARTHING AND BONDING – SUPPLEMENTARY AND MAIN BONDING DIFFERENCES – HOW DO THEY WORK & KEEP US SAFE?

The sort of questions we are asked might include …
What is the difference between Earthing and bonding?
What is the difference between Main Bonding and Supplementary Bonding in a house?
And how does bonding protect me?
Determining the differences between earthing and bonding often causes a little confusion when new to the trade or looking on as a DIYer or handyman. Especially as they use the same green and yellow cables and don’t really seem to do anything.
It’s not uncommon to visit houses where the bonding has been removed by the householder because it “was in the way under the sink and anyway, nothing has happened by taking it off”. As electricians we should be reinstating these connections for the future safety of our customers.
It’s like seat belts or air bags in your car.
You don’t need them until you need them. And then you do!

I wish the books were as simple as this Genius. Dave you are an excellent Teacher in the Electrical field
-
Amazing content, it's much clearer then in books 🙏
-
Thank you ever so much better than class room to be honest 👍👌.
-
Best videos I’ve come across. And I’ve watched a few. Explained simply and clearly. Last one I watched was earth fault loop impedance. Again another great explanation 👍
-
Just looking through the comments and can’t agree more. The earth potential with main bonding is something I’ve always half understood. Knew its importance and understood about the earth fault path but couldn’t get my head round the difference in potentials. Actually can’t believe how simple it is. Very thankful for your video.

Great video, learning lots. Thanks Dave.
-
I really found it hard to get my head around earthing arrangements in genral, this video was amazing and gave me a clear and better understanding on how each cpc system works. Thanks :)
-
As always very informative and well executed.For any learner new to electrics these video would help tremendously.Thanks and keep them flowing 😃👍
-
Thanks again Dave, always Clear and precise well explained, keep up the good work.
-
great contents
-
Another fantastic explanation. Thank you Dave
-
This made loads more sense in helping to understand the potential difference of an exposed conductive part and extraneous in an earth fault when bonded. QQ - to clarify, in the instance of an earth fault, all cpcs / bonding will become live with say 230 volts (as they are all at the same potential, and all connected to the MET) for the period of time it takes the protective device to operate? e.g. 0.4 seconds

Seriously mate, very very well explained!!! Thumbs up and subscribed xx
-
Well and clearly explained and visualised.EXCELKENT ,BIG THANK YOU.
-
Just a brilliantly clear explanation of what was before this a bewildering jumble of words. I understand this now after the one watch! Of course, I will watch a few more times, but I grasped this tonight. I struggled with this before. Well done and thank you.👍
-
great video, well explained
-
Brilliant as always.
-
thanks for your very helpful video as always. Great job by learn electric.
-
Thanks again , I read the regs then listen to you and get a better understanding
-
Thank you very clear and informative.
