so i'm underway on some of the testing of the circuits again i've just write things out on a
scrap piece of paper before i do it on the actual um on the official paperwork so just run through
on some insulation resistance testing done some earth fault impedance testing not got
the results for for the lighting circuits just yet i've got a problem with the lighting circuit
so i haven't done that just yet um as you can see here on circuit number nine
i've got the cables all out here this is one of the ring final circuits
now initially i went round and i did a Zs test on those on them on them circuits
to work out just just to make sure everything was okay so i've got
one two three four five six seven eight nine ten sockets on that ring circuit
now i have already tested this as you can see i've also done my uh little r1 r2 and
rn end to end results and as you can see we've got 999 for r1 r2 is 15.6 and rn is 999 again
so we'll just go through them again just to check so i've got the end to end there
and again it's reading 999
on the cert on the board so on the machine again it's still reading 999 so we go on to the CPC
and i can hear it clicking and this time it's 15 or 16.4 i think i recorded 15.6
so straight away that's showing that this isn't a um a ring circuit okay or somewhere along the line
the ring circuit has been broken so one of the checks i have done then
is because maybe this ring circuit and here which is only controlling two two sockets in the kitchen
maybe that is somehow connected so again i'm just going to link
the line to there it's saying it's not so that's sometimes a problem where
they've just had two ring circuits and they've linked them to and they've got
them around the wrong way so again that's not not the case and do the same on the neutral
now if you look on the insulation resistance for this circuit i haven't got a very good insulation
resistance now all everything is unplugged i think there's 10 sockets so everything's been unplugged
and i've also just done a line to earth test on circuit nine
on both legs because the insulation resistance i was getting when i tested that circuit as a
whole was very poor so we're going to do an insulation resistance test now
between one of the legs of the line we'll turn this to 500 volts and the earth bar so again
okay and that's reading very low there 0.09 and if you see there i've made a recording there
on that one that was .06 this time or that time we'll go on to the other leg
and the other leg looks absolutely fine about 341 and before i measured 334
so again would go through all of the circuit through that so this is
now sort of what you'd probably call further investigation
what am i going to do to this um i'm not really sure at the moment i'm not going to actually do
anything just yet but if you think about it we've got a 32 amp circuit breaker controlling in effect
two radial circuits not a ring circuit so these are only two and a half mil cable so really we
need to downgrade this 32 amp to a 20 amp and i have got a spare 20 amp wirelex circuit breaker
so that's one of the things i will be doing on this eicr is i'll just take this 32 amp out
and i'll stick the 20 amp in there at least then i know that the cable is better protected because
it's a 20 amp rather than a 32 amp i think 22 and a half mils only rated at about 25 amps or
something like that so sticking a 20 amp in there it will be okay apart from that
perhaps i might have to come back and do some further investigation to work out exactly what's
what i probably will i could probably come back and split these two circuits into two radial
circuits i have two 20 amp circuit breakers that would be also a good thing because at the moment
this circuit breaker here is just controlling two sockets in the kitchen and then this one is
controlling everything else so if we added another 20 amp circuit onto it we're then
splitting the these sockets up to give us a bit more um or a little bit better for the customer
again if you look up in here in this junction box one of these cables is connected this cable here
is connected to one leg of the ring so maybe my fault is up in this junction box but i'm
not going to start taking that apart on an EICR that's that could um lead into no end of work and
take a lot longer so that would be something i'd come back to just noticing there as well
i don't know if i said before but there's a broken cable sticking through the ceiling
there anything like that could be the cause of why that ring circuit isn't isn't um reading as a ring
anyway i'll crack on and get on with the world
