Yes Bruce exactly, a MEIWC is an alternative to issuing an EIC.

So If assessor says otherwise after making him read it i will make him eat it lol

cheers to all I was going to ring him again in the morning to re question him on it but cant be bothered if i am honest with you
at this rate i may as well give him one of each for good measure lol

EIC sufficient, just making more complications. Note work done.
Give him some lobby to wash it down. lol.

The EIC should describe the extent of the work covered by the Certificate.
You should only record the results of inspecting and testing the work covered by the EIC.
If you inspect and test any of the existing installation, then you are effectivly conducting a Periodic Inspection, something that the BS7671 prohibits an EIC being used for.

Hi mate
so for the new shed supply and the CCU change am I supposed to carry out a full inspection & test of the installation including existing circuits or just the shed supply and any circuits that are new or added altered that i have carried out work on as surely when you change the overcurrent protective devices by providing a new CCU this would require a full set of tests

Technically when changing a CU, you are not required to test any existing circuits.
This is because before changing the CU, you will already have checked the installation to ascertain that it is suitable to make the alteration.
When checking the installation, you are not required to record any measurements, but many like to conduct an EICR.
It's up to you whether you then after changing the CU, re-test all the circuits and record the results on the EIC.
Some won't bother, some will just transfer the results from tests conducted before the change, some will re-test and others will not have tested before the change, so feel they have to after.

Personally, I always do a full spread of tests after a CU change (as I often find issues which are not picked up with basic tests prior to the change), but as spin says, that's up to you.

I did a A PIR at end of last year and this turned up mutiple issues with the existing CCUs and circuits loads of loose connections
CPC end to end High
step 2 and 3 all sockets gave different readings
It was originally stranded imperials probably al readils and someone has made a ring with multiple sockets spurred of other sockets and possible hidden joints under the floor
but on the lighting I only carried out a IR test with L-N Joined to earth
there were mutiple circuits still connnected going nowhere LOW IR etc etc loads of observations and recommendations

Then I have run a NEW sHed supply in SWA buried in ducting and final circuits for sockets in the shed and lights as well as a further SWA in ducting to a dcecking area to a double socket which supplies 2x sets of 10 LED decking lights
In the house i changed the wylex fuseboard and a existing volex single RCD split load for
a 13 way BG split high integrity
I have also carried out full set of tests and inspected as much of the instalation as i could to rectify as many issues as i could
I had to alter position of water bond as it was after branchwork (pvc fittings and water filter)
A NEW lighting circuit for light under stairs in meter cupboard
removed loads of obsolete circuits whic i had disconnected at time of PIR
Shower was feeding a 230v wall fan in zone 1 direct from the 30A DP pull switch supply side
connector blocks hidden in loft under a ton of insulation no tape loose connections
rodent damage to strappers in loft
the list is endless it would have been a whole lot easier to rewire
If only he hadnt had so much work done which would be affected by a rewire
there were lights in old half of kitchen fed from house lighting and seperate circuit for 4 downlights and flourescent in utility, 3 downlights in soffit

The house lighting highest continuity reading i have had was almost 6 ohms gradually with all loose connections and hidden connectors got it down to 1.71 which is at landing light due to the resistance of the strappers so this is R1 +R2
there is a lighting circuit that did a the house including 5 GU10s in old part of kitchen and attic fluorescent
When carrying out the full set of tests as i was connecting the existing circuits found a LOW IR of 0.14Meg on house lights between L-N
traced to above old part of kitchen
couldnt remove flooorboards due to wooden flooring in all rooms above and newly fitted carpet on landing until speaking to customer
so I Isolated and locked off and informed the customer

I Issued a EIC
for CU change and sub main to shed with final circuits and also the new lighting circuit and I&T of existing circuits some of these i have altered also and ticked the boxes marked additions and alterations for it all
and recorded the details of the fault on lighting that needed urgent remedial action
recorded a full EIC with schedule of inspections and a schedule of test results for all circuits inc continuation sheet for the shed and final circuits

I spoke to customer and arranged to go back but would need to remove bathroom wooden flooring and carpet on landing to find the suspected faulty connection

I found a base of a 3 plate rose no lid nothing jsut a 1.5mm flex connected no earths connected the neutral flex was hanging on By 3 strands and visibly heat damged and so was terminal also the lop terminals had neary burned through to the neutral the flex then went to a connector block and 2.5mm was looped in and out to the 5 gu10s and further connector blocks with 1mm out to individual fittings termianted incorrectly

They had also asked me to sort out the faulty fan i had disconnected in bathroom and the outside lights
I provided a new supply for outside lights and 2 x fcus one to feed a timer for soffit lights and 1 to feed outside switch for PIR flood

I removed al the dodgy wiring for the 5 x GU10s rewired and then added to the newer part of kitchen lights
to create one circuit for kitchen and utility and remove some of the load of the house lighting
so was going to issue a EIC for the 3 circuits affected by my works until elecsa guy reckoned i shoud issue a EIC for new supply and MEIWCs for the additions and alterations
Talk about confusion

anyway cheers guys for all our help and advice

Sounds like you did a thorough and professional job mate. As already said, as long as all test results are good, and you've listed what you did, then everyone should be happy

 

[brucelee]

yeah mate
tried me best still would like to do more but cant for the damge it would cause to all his decoration and fixtures
It would have cost him a fortune for this work done of someone else would have taken it on but think they would have jsut recommended a rewire as it would have been a whole lot easier and quicker

Will be rewiring house lights and sockets in future when he is willing to have the work done
as the house lighting IR is now over 100M its adequate for now and reduced the continuity from almost 6ohms to 1.71ohms
the sockets arent wired conventionally but for now at least they are RCD protected and found mutiple lose connections twisted Ns not in terminal twisted CPCs not in terminal high resistance
the old wylex had about 4 circuits in each of the 4 ways and some of these circuits such as shower was feeding shower , wall fan in zone 1 and old FCU which used to supply his central heating all removed as he has new combi in utility and
cables were coming at the board from all over the shop some damaged some with low Ir
heat damged 6mm earthing and bonding to wylex
mate the list was very long
It was good to do
but i wouldnt like to get to many like that lol

I have also rang elecsa again and as i originaqlly thought and others have stated a EIC is acceptable for the new supply and the additions and alterations so happy days can notify this finally lol

cheers to all for taking the time to reply

Sometimes it is hard to explain fully over the phone, and the tech guys obviously have to interpret what you are telling them. Always worth another phone call if something isn't clear the first time.
