periodic codes

[sparky0000]

hi all,

im just wanting to know a thew codes that im unsure of


on a ringmain circuit there is no end to end on earth to earth and n-n

poor IR readings on sockets as low as 20-60 M ohm

and no heat sleving on bathroom light


thanks

• Code 1 Requires urgent attention
 
• Code 2 Requires improvement
 
• Code 3 Requires further investigation
 
• Code 4 Does not comply with BS 7671

end to end

continuity?

I'd say a 2 if only 1 break in CPC (so long as measured Zs is OK) or a 1 if more than 1 break
poor IR readings on sockets as low as 20-60 M ohm
20M-60M ohms is perfectly acceptable - no code
and no heat sleving on bathroom light
If it's suffering from heat damage then code 2 otherwise I wouldn't code it

thanks

Mine in bold

Have a look at the ESC guidance, loads of good info in it!

sorry i know the codes just unsure wich one to use


yes continuity

 

[PrenticeBoyofDerry]

I'd go
1
nothing
3

prenticeboy

was that code 1 for the first two and no code the heat sleve?

Code 3 is basically for things outside the scope of the PIR hence I wouldn't use a code 3 for this.
Maybe code 2 if there was signs of heat damage or not installed to manufacturers instruction.

After reconsideration, I agree with you, meant to edit last night after my hot cup of coco.

What are the concequences of the ring final being open circuit on CPC and neutral??

What is wrong with 20 meg insulation resistance reading??

Does the bathroom light need heat sleeving??

higher fault loop impedances

Potential for overloading cables depending on how the ring is loaded and where the break is.

Depending on how the break occoured the break itself could a further hazard such as a damaged cable or wires loose in a socket that could fal out or short at any time.

(so long as measured Zs is OK)

Also need to confirm it can handle fault current.

In reality that shouldn't be a problem as a spur only has a single piece of 1.5mm cpc
