Chris is like the videos. I have a question that I hope that you can help with. After a system has been in commission for some time when I have to go and perform a periodic test on the system, performing any test that requires access to the roof is difficult when the scaffolding has been removed. I am thinking of IR tests. Due to the inability gain access during a test on an EICR on a typical electrical installation I would LIM the area with no access. I am hoping and expecting you to say the LIM can be applied to the IR test on a PV system especially if the Panel String produces Open Circuit Voltage in line with expectations regarding the manufacturers figures and the irradiance test on the day. I hope you will comment on this. Thanks for the vids. P.s. I have bought your testing book in the past after viewing other videos.

Thanks for the videos Chris I wish that I had them when I did my BPEC training the videos bring much more clarity to the process and your DC Isolator test connection device will aid further testing. I am not a fan of arcing!

Chris when I did my BPEC training I am happy to report that I argued the points that you made in this video and I agree with you. However your explanation bring so much clarity to the conversation.

Thank you for the information I like the way you explain the work

Hey Chris, great vid. If you don't mind sir, please clear up the following: 1) I assume this is an ungrounded array, meaning neither + or - from the array is solidly or functionally grounded, correct? 2) I understand when you short the array, there is 0 volts at Isc but the array Isc current (I think you said 14A) is still flowing in both cables and now you are back-feeding 500V from the megger to produce a 2nd possibly high leakage current to ground to measure insulation resistance (megger doing ohms law). I understand the megger current is normally very low with good wires but is there an issue with the megger accuracy when both current sources are flowing on the shorted cables at once?

Is you carry out an earth loop test as you would normally the instrument will give you both Ze and PEFC on the same screen. Hope this helps.

Is there a video clip measuring the short-circuit current between L and PE? I want to know the short-circuit current between L and PE that is PE in a TT system. I want to know how many amps the short-circuit current between L and PE will be? Thank you very much, sir.

Can this model test the short-circuit current between L and L?

The only tester of any kind in the world that I've seen that for some reason has OFF function in the middle of the selector scale, which basically means it's unavoidable to cycle through tests without switching it off and on. again and again..???

Wonderful explanation of how to wire a s plan system first class

Very clearly explained!

The reason we have DC isolators adjacent to the Inverter is so if the Inverter needs to be serviced off site, we can isolate the 'Tails' that go to the Inverter, instead of leaving the Live MC4 end waving in the breeze. But some Inverters have an integrated Isolator that you can unclip from the Main Inverter, so will negate the need for a seperate DC isolator

Love all of Chris videos.😀

Christopher Kitcher is one of the best at explaining various aspects of the electrician's trade.

How did you set up the handsfree function? My tester says invalid connection when I press test?

Hi Chris! You make it all straight forward!great clarity in your videos! 😊Regards mg.

Hi Chris got a diagram of the connections for your DC test box?

Hi great videos just out of curiosity did you ever do the video for bonding solar panels on metal roof

Hi bro you are best very good 👍

Thank you for your patience and dedication. Your guidance has been invaluable, and I appreciate your commitment to helping me improve.

really great vid i have been thinking of an upgrade to this tester, what do you think of it could you do a review thank you

Hi sir how do you test single phase motor

That made up my mind regarding buying one for nearly 2 grand. Not for me, to slow. I will stick with my supposedly accurate certed old megger that is a lot faster and has auto live readings. Really Megger.

What should be the range of accurate resistance values for eleçtrical 3 phase motors

Haven't been seeing you for a while! Hope you're doing well sir

Thank you sir

It's very pleasure to see you again, sir.

Good to see you well sir . The sound quality wasn't that good . Thanks though .

I understand the theory of what the instrument is doing, but I thought that we don’t generally measure volt drop in this way, as the test at origin and at the remote location, really needs to be performed simultaneously with the same instrument. Due to fluctuations naturally occurring in the supply voltage. If you test at origin then few minutes later test at the remote point the supply voltage will naturally move around due to loads being switched on and off (perhaps in neighbouring properties) Great video though Chris👍👍

nice 😀

Good to see you doing videos again Chris , I always liked your clear and concise style of explaining things .

great video as always. nice clear explanations

Hi Chris, thanks for your videos, Any idea when the DC Test Device build video will be available?

Thank you for sharing this great information.

Thank you Sir!

Very good explanation and video ❤❤❤

Hi Chris, what was the lead you used from the bottom of the isolator to the Megger tester?

I’m sorry Gary but you are wrong. If you look the socket is on a plastic containment system ( upvc conduit). Parallel path? I don’t think so! Mind you the vids are there for you guys to learn from and it’s nice that you are watching them, I hope they help you. Best regards, Chris

Yes great vid but.. not a true Readings with Parallel paths Connected so… still be close though but all your lads learning don’t do this way disconnect earth GB LEC

Great idea with the isolator; I'm going to make one. I assume that, since this is a 2-pole isolator, it connects diagonally. So, terminal 1 connects to 4, and 3 connects to 2. Then make a link between 2 and 4 with a second cable in terminal 4 with a female MC4 connector on it, correct?

and how did u know that coil is beggining leads and ending leads?

Awsome😊

Sir, when you connect the positive and the Negative ends of your solar PV string into the isolator, you basically shorted them? Will that be ok? No damage to the panels. Pardon my being a newbie. 😅

thanks

Still awsome😊

I used the Ci rating factor from the OSG accidentally. Easily done. It's not surrounded by insulation, just laying on top

Thanks so much! What's the HP of this motor?

I can see this video has been around for a few years and hope my comment finds you in good health. These instructions may just have saved me a call to the plumber. Time will tell. But looking good so far, .. just a little spin was all it needed. Thanks a bunch!
