Wow this is a very good 'go to' link for knowledge on stuff I've forgotten lol Thanks as I've learned even though being a sparky for 30 years as we are always learning and we should never be too old or proud to learn to be a better sparks as it good to know your stuff
Thanks for the great comment and so glad you are finding it useful. Almost 100 videos now and still lots more to come. Thanks for watching, appreciated. Dave.
This video is brilliant. Very clear & expertly explained. Thank you. Do you have a video explaining SPD's & AFDD's and when these are / must be installed?
Daniel, You will find SPDs on this link th-cam.com/video/CCZJ0CPOR2U/w-d-xo.html And AFDDs on this one th-cam.com/video/vwB21r66faM/w-d-xo.html Thanks for watching, Dave.
As you have noticed, I am watching your nice tutorial videos and asking questions 😃 , my most recent question is: can't we use RCD's for functional switching or it is just forgotten in the table?
Thanks for watching Sajad, appreciated. Yes, RCDs can be used for functional switching. Look at Table 537.4 on page 181 in the Wiring Regs book. Keep watching, lots more to come. Dave.
Good informative video again. why is it that if for eg im rewiring a ceiling rose and obviously the power is off if 2 of the conductors happen to touch im not sure if its line and neutral or line and cpc the R.C.D trips? Is it due to very small amount of current still in the line? This could be a potential problem if someone is working from home on a computer or something. Thankyou for such a detailed explanation.
This happens sometimes. It can help to remove both live wires at the CU. Sometimes there is just enough induced current from nearby conductors to make the RCD think there is a fault.
Walid, is that a typo rccbo - If you mean RCBO it is explained in the video. If you mean RCCB, as used in some small CUs and garage units, they do not have overcurrent protection so are the same as the RCD explanation. Hope this helps.
Hi Sir...have a question regarding sub main fuses...if we have a 100 amp fuse at the main head ...and in the ryfield board there is 60 amp fuses...then from there it goes to the meter...the main board is (eg) upstairs....should the isolaor feeding the distribution board upstairs ( or say first floor) be a straight isolator or a fuse isolator...and what size fuse should that be...taking into account discrimination...
Depends on length from intake to CU. More than say 5 metres the network operators like to see fuses protecting the meter tails. But you can always install a fuse isolator with a BS88-2 fuse. It looks like you already have 60 amps in there so as this is on the load side 60 amps.
A switch is any accessory that turns something on or off, lights, cooker, motor etc. for every day use and can be single pole, double or more. Generally an isolator will disconnect all live conductors to a circuit or part of a circuit and can often be locked off to safely isolate the installation. Hope this helps, electrics could have its own 400 page dictionary.

Absolutely right Tony. We should never stop learning. Thanks for watching. Dave.
I'm a new subscriber doing my Level 3 course. This channel is brilliant 👌
Thanks for the great comment and so glad you are finding it useful. Almost 100 videos now and still lots more to come. Thanks for watching, appreciated. Dave.
Great video. Really appreciate your efforts to educate the world on all things electrics
Thank you, great feedback. We try our best and really appreciate comments like this.
Dave.
As always very good presentation. Short and concise. BRAVO!
Glad you enjoyed it Omar, Thanks. Dave
These videos are excellent and so clear and helpful. Thank you!

@@learnelectrics4402 should have looked before asking. Found it and both videos very helpful and informative. Thank you 👍🏻

Wow! This is very informative, thanks for sharing it with us. It worth it and the best tutorial on the topic for me...wtc
Happy to help. Dave.

thanks that was great as usual.
Thank you Karamat, appreciated.
Very good and simple explanation, what's different with rccbo ? Thanks

Thanks for very informative video
And thank you too for the positive comments. Glad you are enjoying them, lots more on the way. Dave.
Will an RCD work if the is no earthing in the house?? Thanks!
If there is no earthing and no leakage currents then there will be no difference between L and N so no. You can always check with a clamp meter.
Thank you very much
Thanks Jackson and thank you for watching. Dave.
What's the difference between a switch an an isolator?
A switch is any accessory that turns something on or off, lights, cooker, motor etc. for every day use and can be single pole, double or more.
Generally an isolator will disconnect all live conductors to a circuit or part of a circuit and can often be locked off to safely isolate the installation.

Brilliant, keep the vids coming..👍
Thanks for the comments, lots more to come. Dave.
Well understood
Keep learning, its a good trade.
