Yet another excellent video from Learn Electrics which has helped clarify in further details the content of BS7671 wiring regs. Thank you for this upload it has been really helpful for my 18th edition studying
Excellent video, as ever! I’m curious how the zones would be measured in an L-shaped bathroom with a shower/bath at one end? I guess the 2.5m would go diagonally to the corner, and then follow along the edge of the wall? I’ve seen an example where following the wall would allow a socket 2.5m from the shower but if the 2.5m can pass directly through the wall (shortest path, regardless of obstacle) the distance would be less than 2.5m. I guess the former would be more correct, not least because in this circumstance a socket would be totally out of sight/inaccessible from the shower because it is around a corner….
Think of it this way. Everywhere a 0.6m piece of string can reach and still be in contact with the bathtub is zone 2. And everywhere a 2.5m string can reach and still touch the bath is the outside zone area. The string can go round corners, round partitions, anywhere you want. As long as it maintains contact with the bath. So you could end up with a funny looking shape for the zones as you suggest. Hope this helps, we have a video on shower zones coming up soon and it is covered in that.
Hi, thank you for the videos they are really helpful. I am training to become a qualify electrician and they have been helping me throughout. I have one question most of your videos are giving page numbers on the blue book. If you can make a vid with the latest number page that will be very helpful ( Like the most important pages) Thank you again
If it has a blue book on the starting slide for the video, it relates to the blue book. If it has a brown book on the video then page numbers are for the brown book. Go to LearnElectrics.com and put Amendment 2 into the search box and you will get a list of links direct to the Brown book, including questions and answers for the exam. Good luck. Dave.
Excellent content as usual. Got a question re low voltage SElV 'circuits' .. if a shaver socket is supplied by 240v . But is in zone two. And is ipx4. Is it allowed ? Even though just behind it is 240v? Not all switches and sockets are fitted well to the wall and look like water could get behind..
@@learnelectrics4402 Does the regulations require it to be ip rated? Or is a normal switch fine as long as its outside of zone 2. Or as a minimum the ip20 for water ingress protection?
If the toilet is in the zones measured from the bathtub then it comes under whichever zone it is in. Everything is measured from the bathtub or shower basin.

If it is the BS EN 61558 then yes. It is 240V in and 240V out, but the output is electrically separated. Its not SELV, its SLV.
Can you have a light switch with ipx4 rating in the outside the zones area?
Yes you can. Thanks for watching.
@@learnelectrics4402 Does the regulations require it to be ip rated? Or is a normal switch fine as long as its outside of zone 2. Or as a minimum the ip20 for water ingress protection?
Really love your content. How do you create your art work?
Thanks for the compliments, appreciated. How? Lots of hard work and many years of finding the methods. thanks for watching.
Can a shower wall isolator switch be installed in the outside the zones area?
Absolutely yes, best place for it.
@@learnelectrics4402 thanks, you said in once if your earlier videos that it needs to be installed outside the bathroom so I wasn’t sure
Light switches in a bathroom are OK as long as they are 0.6m from zone 1?
Ceiling pull switches or SELV
Isn't that outside of zones though, making a light switch acceptable?
so just to clarify electric towel rails can installed on zone 1 & 2 ?
Take a look at On Site Guide, Table 8.1, p104. If appropriate IP rating for the zone, then yes.
@@learnelectrics4402 thank you so much for the reply. I really appreciate it
Another new topic is covered 🎉
Thanks for watching, appreciated,
Is any reg for loo/toilet wc only /sink and toilet only
Does it have a bath or a shower? That is the only question. No bath, no shower, then the zones do not apply. Hope this helps, Dave.
@@learnelectrics4402 no bath, no shower
Does the toilet itself come under zone 0?
If the toilet is in the zones measured from the bathtub then it comes under whichever zone it is in.
Everything is measured from the bathtub or shower basin.
Thank you
Thanks to you too for watching. Dave.
👌
Thanks Brian.
Excellent video! Passed my 18th edition watched all your videos top man👍🫡
Nice work, well done. It's a good trade to be in, taken me around the world working. Thanks for watching. More to come.
