5 Deadly Hidden Electrical Faults

Electricity can be very dangerous, more so when you don't even know what you're doing. Unfortunately, many homeowners still decide to work on their own electrics despite the potential risks. In this episode, we're challenging our apprentice Reuben to find five electrical faults, that are far more common than you may think.

It’s lovely to see Reuben’s confidence growing. His sense of humour is coming to the fore with the increased confidence. Great video guys and a real life fault finding course! Very good!

[andrewbrady]

The problem isn’t DIY’rs, it’s the trades race to the lowest possible standard bottom over the last 20 years.

[JGE_Installations]

Impressed with Reuben, some electricians I work with wouldn’t be that confident with those faults

[owenlerry]

Well done Reuben, having someone like John teach you like this & give you such knowledge is golden & should fill you with confidence, just keep learning put the hard work in at college & you will become a great electrician.

[michaelanderson]

Well done guys! That’s a great way to teach next generation electricians about the dangers and importance of electrical safety!!👍👍.

[kinkam]

is it me or does Jordan's consumer unit look a bit messy? LOL

[acespark]

Great video simulating real life situations is difficult, but I liked how you let Reuben try to work it out as he will have to do on his AM2 or AM2s, and in the real world. Training like this is invaluable 👍🏻

Thanks, John, for explaining the need for proper polarity. Here in Denmark we don't have polarity on our electrical system. Everything is still wired according to the proper ISO polarity, but double-pole (or four pole for 400 V) breakers have been a legal requirement since 1975, and were used for several years before that, so it's not something we consider a big deal. It's still important to pay attention to it in old installations that have single pole breakers, but there are luckily very few of those left that have yet to be replaced - since our regulation require, that whenever you do anything that requires making changes to the board (like adding a circuit or replacing the breakers) the whole board has to replaced with one that complies with current regulation - it's a pricey rule, but ensures you don't pull more out of the board than it was designed for.

One criticism about this test, though: NEVER trust the colours of the wires, especially when fixing DIY installations. And although you explained how a ring works and should work, you also succeeded in explaining why they're a terrible idea, which is the reason no other country uses them, or allow that high a rating on such a thin cable.

Probably the best video you have done in a while. Educational. And makes a difference to the usual just fitting car chargers.

[raymondburke]

Really good information. John, your good at explaining things and you have patience….a rare quality these days..👌⚡️

[TheXeroid]

Excellent video. John is an excellent tutor and explains things clearly. Reuben is cooking on gas too. One thing, whoever out that washing machine drain next to the DB, wants shooting. One blocked drain away from a lot of hassle.

[graemescott]

Well done John and Reuben that was a great teaching episode both from the material and the way that John mentored Reuben.

[Rockspencer]

Amazing video-idea and execution! Educational and entertaining as always, guys.

From this video I decided to check one of the wall sockets I replaced 3 years ago. One of the wires were loose. Potentially a life saver. Thanks guys

[kittsdiy]

6:25 fun fact in Germany/holland/Begium we don't have polarized sockets.. L on the left or N on the left is both ok . Also you can reverse the plugs in Germany/Holland ( shucko) in Belgium we have earth pin .. buth double insulated appliences you still kan put it in both ways . And even more fun fact ..in Belgium we still have a lot of grids 3X230V .. so in a socket you have no neutral it's L1 & L2 .. of L3 & L2 etc .. ( also main reason why we all have use double pole protected brakers .. so on both wires fused )

[omaximal]

Thank you once again, I'm about to do my fault testing on my course soon n this has been helpful! Specially when they talk about polarity!

[dobplastering]

Great video really enjoy these sorts of videos really helps thanks !

[lonewolfgeoff]

ok now we know reubens grasp of the force is nearly complete! absolutely awesome! 😁

[sukhi]

Great video 👍 Huge amount of knowledge you guys have! I definitely learnt some things from this video! 👌

[The_Real_Pope]

Who’d have thought a “neat or not neat” reveal of Jordan’s consumer unit would be that birds nest!
