Proving Your Neutral Electrical Connections

[telectrix]

only let me do one option!
to see who has voted just left click on any of the scores at the right hand side and all is revealed (did say a public vote)

tried that. takes me to photobucket asnd a load of spam.

Thats because you did it on my image thats hosted on photobucket try it on the actual poll results on page 1

M,

Do you?

Yes!!!

A good few years ago I read a post on here from a wise old spark who said that, as the last person in the consumer unit, it's you responsibility to make sure EVERY connection is left secure. Since then that's what I've done, admittedly using the self-calibrating wrist method.

Thermographic surveys help with this problem, but only if the equipment under test is running/energised.

One of the options should be:

"when you have to open a CU do you check all the connections for tightness?"

Thanks for keeping that wisdom alive ...

M, I just wanted your confirmation that this is what you do ... I did not doubt it for 1 ns!

I have nothing against the self-calibrated wrist of a time-served spark, or a the 17 Day or Electrical Trainee who competently discharges their responsibilities in a professional manner! I have no time for anyone who does not act in a professional manner.

Torque screwdrivers ha ha invested in a set not with my Money lol but even so a good buy been nipping breakers up at work to 2 NM

Dave tight is good enough trust me.

Yeah I think option 2 and 3 should be linked together TBH.
Either way rawk that biatch down!

I think the first and last options should be grouped together also.

If I'm measuring a Zs, I'll usually do the Z(line) at the same time; it's an easy check that there's a decent neutral connection. It's just another button to push on the MFT if you've got three test leads connected already.

(BTW, what's the proper symbol for line impedance?)

Nowt in BS 7671 on the subject of the Line-Neutral impedance ... another sign in my book, that the regulations focus so much on the safety function of an installation so as to leave a gaping hole in the safety of the functional purpose of an installation, to distribute power!

flex_m ... really, you let the side down there, what do they teach on these courses ...

I wrote something then edited it a few mins later then it come up I wasn't logged in so I just deleted it as couldn't be bothered to write it out again lol.

LMSO! I get pretty frustrated ... I have lost a number of well penned 'thoughts for the day'. I now copy the text to an iPad note if I get the ominous 'you do not have permission ... ' message!

Does this mean your MFT will allow you to do a Zs without a N connction? My Metrel won't

Never having owned a metrel I ask because it is surprising
3 lead test,neutral and earth leads are shorted what is the outcome ?

Lol yes It's very frustrating when it happens, I normally copy and then paste it when I log back in but It didn't seem to work that time.

Cannot comment on the Metrel

My Megger requires the N for the No-trip test (three lead test) on the Hi-current test the N and E leads are connected together (effectively a two lead test), for testing ZP-N the Hi-current test would suffice because this would not trip any RCD.
