Say what you see…..
And a few more words

I wish there was a facepalm emoji

I know, right?

 

[Mike Johnson]

How to fit a light bulb and the different type of fittings next, Oh hang on that could be useful.

Can't see them in my end, they're all blank. Like dels mind

Del just removing the main earth from a live TP board.

Poor isn't it... Notice his lack of replies to the comments pointing it out.
The thing is, we all probably make occasional mistakes at work, and realise. He's filmed it, edited and uploaded to YouTube and not realised.

Dangerous would be the word i'd use!

That's because he's incompetent. It's embarrassing for NIC that he's an approved contractor.

I have worked with Approved contractors Way Way worse than Del , in fact they make Del look like a Pro

Why would you remove the Earth when testing a TP board?

 

[mainline]

Why would you remove the Earth when testing a TP board?

Ze comes to mind.

 

[Mike Johnson]

Then immediately re-connect?

 

[oscar21]

I don't get it, if you disconnect the earth to get a true Ze the you test on the incoming earth cable, not the dis board where he clipped his crock clip.

also do those newer meggers do P-P IPF nowadays, I was waiting for the bang. Day one of the 2391 course and our tutor said never ever test phase to phase whilst doing IPF with a single phase tester if you still want eyebrows. I've always doubled the highest single phase reading.

I didn't look at the video, i just replied to the “why would anyone disconnect the main earth”.

Its Dels attempt to do PSCC.
He's not interested in PEFC.

I looked at the vid a few times, the main TP switch was in off position thats good should of locked it off, now this is the confusing bit Del disconnected the main earth (to the DB) lead away from the MET block because multiple bonds on the block, but still had his clips on it in the DB with all earths still connected picking up other paths. IMO this was not a true Ze. He should of taken the main earth lead out of the MET block coming from the cutout and put his clip on that.

As far as I know all of the megger, and most other name brand, testers have done loop tests at 415V for a long time.

I've certainly always tested phase to phase with both my megger MFT and megger high resolution loop tester.

If anyone is manufacturing a tester which would fail catastrophically if connected phase to phase then it is not fit to be on the market. Even if it can't test at that voltage it should be able to handle being connected to it and at worst be able to safely contain any failure which occurs due to it.

Meggers from 15xx onwards will in all cases handle phase to phase on high-current. The 15xx gets very upset if you accidentally select no-trip and connect phase to phase. The manual says it isn't 'supported' but doesn't talk about the undocumented internal fuse! The 17xx onwards just beeps.

It can be the case (not wishing to cast general aspersions) that college tutors have been out of the day-to-day game for a while and not been exposed to more recent equipment. He is right that you could once easily break a tester doing this:

By the time Robin became Kewtech (in simple terms), the KT63 doesn't blow up but also doesn't handle phase to phase.

So in general, if you have a Megger, crack on!

It was in 1999 I did my 2391 so he was probably correct at the time. I've never had one of the more posey meters (fluke/megger etc) and just had something cheap and functional, I currently have a KT63 and before that I had a Unitest one which I've still got in the van as a backup, 20 years old and still works perfect.

Unless there was a bit of editing in the video he seemed to be testing the socket under the sink with no fuse in the spur... in fact the client actually says at the start.. "I took out the fuse"!!

That'll be £500 an hour sir.
