Passed my 18th edition and 3 other exams. I failed my condition reporting and pat testing so I need to study some more but thanks for all your videos

So I have a 120v 80w amplifier that popped a fuse without an amp marking just 250v. 80/120=.66 Does that mean I need a .5 amp fuse?

Currently doing a £1800 electrical course, to then find your channel where all the info is free. I learn more from these videos than the course. So thank you for the help. Top man.

Hi Dave, Thank you for the great content as always. Amazing work and information provided. I wanted to ask a question, why would the RCD trip when ZS testing and I get no reading. Please if you could have an idea of what this could be? Thanks

I have a hot to ground that has 120v and 17v to neutral. Similar receptacle has the opposite.. is this a neutral open?

where does the leakage current go if there is no earth, like in older lighting circuits for example? What would happen if you borrowed a cpc from a nearby socket as a less disruptive method of earthing circuit? Would this just mess up the earth fault loop impedance? Thanks

Hello, Starting course in September , just trying to learn some basics before hand , and this was very useful to watch . Thank you so much time well spent and was well worth it . Please keep up the great work 🙏.

How to be certified to Local standards regarding the requirements for electrical installations - (UK equivalent would be IEE Wiring Regulations 18th Edition) ........?????? i want to get certified how to apply can anyone guide?

We don't get clarity voice

Thank you for your content, easily one of the best explanations I’ve seen on this subject

Clear explanations with attractive pictures

Hi ! So 100 ma rcd is not required for a meter tails?

About to take mine in the next couple of weeks

Beautifully explained 👌👍🏼

Good video again. Can I suggest a video in relation to certification about the notices that have to be attached to the consumer unit or adjacent to it (or not now) I’m thinking schedules and rcd checks, next inspection etc and what has to be at the board and what can be handed over with say the certificate.

Many thanks, superbly explained and as always much appreciated, thank you Dave!

Another top video, thankyou. Can I just ask then in reference to this when completing a certificate and it asks for the tabulated max Zs before your actual test reading, I’m assuming they want the max reading from the tables in 7671 and not the tables in the OSG?

perfect explanation , thank you

Is it permissible to install two live wires to an MCB? In other words, two incoming cables (e.g. both for lights only) with both live wires to the 6A MCB, two neutrals to the neutral bar and two earths to the earth bar.

thank you easy

Excellent 👍

Your explanations are much easier to understand than college, thank you Dave .😊

Excellent

Thankyou

I would like to thank you sir, thanks to your videos i was able to pass the exam with 85 percent, im not even from an electrical background.

Dear Dave. I was assuming voltage drop would be the 2.16v X 2 because of live and nuetral

Start my 2391-52 on Monday, really great videos, thank you very much!

Thanks Dave for the clarity in your delivery of the subject. I admire your passion and commitment to teach, which truly shines through considering you are going through cancer treatment at the moment. Thanks for your dedication with this, I truly appreciate what you do. Praying your treatment goes well. God bless you 🙏🏽

Hi, You have given a case. A 3 phase transformer present which drives 8 houses. Each phase has a fuse before reaching the house, inside house thorough MCBs home appliances are connected. Few appliances are running in few houses. Suddenly a bird hit one of the phase of transformer and it's link blown. In house 3, AC got blown which in running state. House 4 - 3 fans blown 2 running state 1 off state. Seen that neutral wires are blown and inside windings are blown. 1. Why not all devices blown in other houses? 2. in house 4, why all devices not impacted? 3. How does the devices affected which are in off state also ? 4. Good to hear the detailed analysis report explaining the cause and internal behaviour. 5. Tell the exact precautions which are needed to handle such situations in future. 6. How can we test the neutral and earthing fine at transformer and at home

Can not be explained easier. Thank you

Complete clarity! Just enabled me to fix a tripping RCD in my out building. Many thanks!

Thanks a lot

why did you do kw/230 in question 5 and kw/240 in question 6 ? because the first gives you 13.1 amps and the latter gives you 12.5 amps this giving two different answers both of which options in the answer box. TIA

Thank you so much for these videos, by far the clearest explanations I've seen. But just to clarify, if a lighting circuit has multiple points (e.g. several rooms each with a ceiling rose/ switch) presumably each and every one of the rooms needs to be tested for continuity at the ceiling rose and the switch as described in your video. If that is the case what R1+R2 reading is recorded, the highest?

Hi love the videos. Always come back to your content. Ok to ask a question tho. Client is upgrading to 3 phase from 2 phases in the application it asks for the kva. The upgrade is for 10 flats. Where would you get the figures for the equations if you don’t know what the main fuses will be. For example if you looking to fit a 315 amp 10 way distribution GFP10. Would you put 315 and 400 v ? Hope that’s clear enough. Thanks again

It would have been a great video if the mechanism by which bonding or not bonding causes shock picturially, then follow all the above video, like how a path for current to flow to the oil tank comes from and how that path possibly cause shock, lets say it come from the house through the ground to the tank then it has got to return to the house, if someone touches the oil tank nothing will happen and does touching the ground at some point go to the oil tank, or the oil tank already have live hot wire......

this is probably a stupid question but if in a radial current is travelling back on the live whats the neutral doing ?

this is probably a stupid question but if its travelling back on the live whats the neutral doing ?

@learnelectrics4402 Where can I sign up for "exam only" ? please help I live in northampton

Good video again Dave. I take if for some reason you have already carried out your Ze then you have already proved continuity of the main earth and therefore the pfc tests would not require a test with the main earth removed? I’m lucky in that my mft gets all these results at once.

The wealth of knowledge on RUclips is crazy, thanks for taking the time to put this together so well!

great basic electronics description.

Brill explanation

First video I see from your channel, amazing 👏. Thank you for your content sir.
