Help r2 problems

[brightspark08]

Hi all just after a little help here,
Took on a job which another spark started and didnt finish in a kitchen,
Tested ring r1 r2 rn only as I had to shoot off, gonna carry on testing tomorrow
r1 0.28
r2 0.03
rn 0.28
im trying to determine why the earth is so low any help would be great as i have never come across this b4 ring is 2.5 with 1.5 earth
Thanks in advance

Parallel earth paths somewhere.

CPCs twisted in back of CCU or as marc says parallel earth paths

ok Thanks,
what would i put on the cert with regards to such a low reading,

You might want to investigate it first, just to be sure that earth is a proper ring to the circuit.

Testing at the db normally removes the paralell paths. However if you have flush pattresses joined with those box joiner thingys then probably not.

Agreed, Find out whats happening...

CPC's aren't in one piece of sleeving in the CU are they? Or touching each other in the DB. Could be as simple as that...

Test R1+R2 at each socket should have continuous/same readings apart from spurs......

As long as the Zs is low enough just Make a note on the cert that CPC has parallel path

 

[somersetsparks]

Is it even worth noting provided the readings are good and continuity can be proved, paralell paths are good!

this is a job that needs sorting. he needs to get to the bottom of this, as the bishop said to the actress, bending her over the table.

Heating off the Kitchen ring?

 

[markc123]

You took on a job another spark walked away from...was he a spark?

What im saying is : Does everything look in good nick? If theres been a DIY monstrosity let loose then the parallel path could literally be anywhere.

Could be loose connections aswell at several back boxes, make sure everything is nice and tight. Hope you get to the bottom of it, but as said - it definitley needs investigating/sorting out.

Has a bond been taken off a socket , to any pipes. Just a thought.

 

[MarkieSparkie]

It might have a large CSA high integrity CPC.

boiler connected to kitchen ring getting parallel path through gas and water bonds
