Comparing Testers

[timhoward]

While I have more testers of various ages that I know what to do with, I don't have anything that does a 2 wire no-trip loop test.
Normally this doesn't bother me as in the past I've observed such tests are unreliable and rarely repeatable.

The other day I had a commercial testing job with lots of grid light switches where it would have been rather handy. (Or at least quicker)
I'm vaguely toying with getting a newer tester that has this test.

I'm aware that the following have this feature:
Megger 17x1
Kewtech KT66DL
Later Megger LTW testers.

Are there other testers out there that do a 2 wire no trip loop? e.g. do any Fluke testers?
Don't worry, I'll very rarely use it!

Can you just get a spare set of leads and cut and rejoin the NandE together ?

I'm fairly sure that would trip RCD instantly, as part of the 3 wire no-trip test is a higher current L-N test, at least that is true on the 15xx series.

I have an old Robin EFLI tester and Im sure you can EFLI test at switches by putting the earth lead and N to the back of the box without it banging out an RCD. It has the old D lock which pulses / blinds the RCD iirc

I like my Kewtech, it's cycles quite intuitively through from dead to live tests on the mode dial. Only gripe is the backlight doesn't stay on for long
