Ring continuity

[Weaver83]

what circumstance??? Hmmmmmm, let me think??? If it is a RADIAL CIRCUIT??? :tongue3::tongue3::tongue3: sorry could not resist, allways test as you not know if there has been any previous work been done, just be safe.

I would have thought that during an inspection and test this would be required even with previous circuit details etc, but it was a question on a 2391 test worth 3 marks, any other suggestions.

No. IEE Guidance Note 3 specifically states that it is not required.

What is EICR?

What is EICR?

Electrical Installation Condition Report - replaced PIR on the 1st Jan 2012

If your visual is unsatisfactory, signs of overheating with possible crumbled insulation giving wrong readings, etc

and there's me thinking it was ERIC, the white horse that went into a pub, and the landlord said to him " we have a whisky named after you" . and the horse said "fancy naming a whisky eric."

During periodic inspection and testing where there are records of ring final circuit continuity tests and where there is no evidence of any alterations to the ring final circuit then it is not necessary.

That kind of beats the point of doin a EICR. Might as well copy all the results from the last Periodic

If this is an exam question, then to my mind the answer should be: During a PIR/EICR and the circuit cannot be de-energized due to limitations.
In real life, I would conduct a Zs test and PSSC test at each outlet, if the readings are all essentially the same (assuming no spurs) then this would indicate the conductors are continuous.
If there is a break in either the line or earth, the Zs readings should increase as you progress around the ring working from the DB, until the break, when the readings should start to decrease as you get closer to the DB.
If there is a break in either the line or neutral, PSSC readings should decrease, then increase after the break.
If both readings indicate a break, then it is a break in the line conductor or perhaps all three conductors, if only one set of readings indicates a break, then it would be in either the CPC (Zs) or neutral (PSSC), depending on which set indicates a break.
