Fault on lighting cct prevents taking Zs

[Nigel]

Perhaps the switch is the furthest point!

Not sure that is even possible.

Not sure that is even possible.

What that it isn't or can't be the furthest point?

Not sure that is even possible.

Maybe in metres, but not in Ohms.

How can a switch be the furthest point?

Hi All

Taking a Zs from a light switch and am reading 160 volts between L & E.
What would you code this. I think it could be a neutral fault but I don't have the time available to investigate. The location is a hotel room.

Out of curiosity why are you quoting the units of zs in volts??
I thought it is measured in ohm

Yes Zs is measured in ohms but most testers give a voltage indication prior to the test.

And some testers won't do a Zs test with readings like that ...

That's lovely, but as far as I know completly irrelevant to your original question and any testing carried out to bs7671.
This suggests you have less than a years experience of working on installations at lv and to bs7671, so approximately the same experience as a first/second year apprentice.

I agree with your 1 year experience wrt the UK. I think you should take into consideration my 40 years experience on projects in the mining industry in southern and East Africa, working to the mining regs
I served my apprenticeship(5 years)in the UK. The bit about 11kV etc was me having a hissy fit. (Western10) thought it funny.Sorted out the fault today. I was looking for coding. In South Africa the mines set their own more stringent regs i.e lack of labelling is a C1. So I just wanted to know what the forum thought

Do enlighten us, what is the joke?
You are carrying out an eicr, what is the joke?
Electrical safety at any voltage is far from a joke, if you have a clue you will realise electricity can, and will, kill without any regard for your opinion of whether it is funny or not.

Personally I don't care, but I'm lead to believe that the death of humans is unacceptable?

However I am curious as to how a liver and bacon casserole would taste with hunan liver? I've made it with all of the commonly available livers but humans are somewhat harder to come by for some reason? Perhaps once a few people have died from your approach to electrical safety you could cut out their livers and send them to me, I'll be happy to invite you to dinner to try this particular delicacy.

I think admin need to change your screen name to Hannibal Lector lol

Ok. Out if inteest, Where did you find the broken / disconnected cpc then?

I take safety very seriously the nature of my previous work dictates that. The joke was me having a hissy fit wrt 11kV not the fault.
I 'm sorry I brought out the Hanibal Lector in you(that is a joke)

On the cu tightened up all terminals on earth & Neutral bars.

Dont get mixed up with mines regs ,they are completely different from BS7671.
Forget about them and get up to speed with 18th Edition

 

[Michael J]

Completed the 18th it's just that coding is a contentious issue. Some say they will code 2 others will say code three.

 

[Michael J]

High level lights would be my guess.

Where possible I like to use my lightmate and wandering lead
