Electrical Installation Installation and Testing

[SaladFingers]

If I put in the measured results BC would raise an eyebow wouldn't they?

Why?

You don't actually need to do any testing for the BC. If the work is done under building regs they do the testing.

For my LA (SLDC) there are different costs depending whether you do testing or not. For minor electrical works it's about £150 if you can provide test results, or about £225 if you can't. So it seems that whilst (I believe) they can't charge for testing, they simply have different charges depending on whether they need to or not.

Cos my Zs is higher than the the calculated (which must be due to the "no trip" function being untrustworthy I believe).

Then enter the Ze+R1+R2 figure.

Is the sum of two measurements a calculation or a measurement?

I consider a calculation to be the result of cable length and resistance per metre.
i.e. that done at design stage.

Yes I am planning to enter the SUM of the measured Ze plus the measured R1+R2 - This would be a calculation, being the sum of two measurements (as opposed to going to a socket and doing a Zs test, which would be a measurement

I was simply answering the OP who was asking why they'd raise an eyebrow - perhaps they wouldn't raise an eyebrow if I entered a Zs which was higher than the measured Ze plus the measured R1+R2.

Someone who has learnt the importance of testing, and is using the correct route to notify/certify, I take my hat off to you sir

Thanks Londonboy, I have enjoyed it immensly, and even to my surprise found myself putting in calls to niceic, napit, elecsa a couple lof weeks ago to find out how much it would be to join and what would be involved, as I'm between jobs at the moment. I think I could get the C&G Level 2, and they all said they could use the recent work as evidence for up to a year, but I don't think I'm the right sort of person to be able to make a business out of it ... and I'm sure it's a pretty tough journey getting to be competent enough to do it for other people.

I normally bypass the RCD for Zs testing now as my no trip Zs readings were not reliable.

Interesting. I have been considering a new multifunction and one of the reasons I kept telling myself it was worth doing was for the ability to do a no trip Zs measurement. Are no trip Zs readings that unstable?
( I usually do Ze +R1+R2 )

Can't say a high impedance tester has ever affected my results.

He should do them for himself though.

They can.

 

[SaladFingers]

They can.

For their prices they can do one.

For their prices they can do one.

What choice would you have? Break the law?

Not at all, notify and show them your test result schedule.

 

[ban-all-sheds]

Explain how you would notify and not pay their prices?
