Board change

SScho:

but in the case of just a board replacement, it will not be for the purposes of initial verification.

I don't think you've quite understood... Where are you getting this information? You need to go over the process of initial verification when you change a board, exactly as you would when you have a brand new installation.


The Regs state that you shouldn't use a minor works certificate for a board change, and that you should use the Installation Certificate (with the schedule of inspections and schedule of test results.)


 

 

If a DB change, then on the first section of EIC [ where you have 3 tick box options] you do not tick "new"

You need to go over the process of initial verification when you change a board, exactly as you would when you have a brand new installation.

No. Initial verification has been and gone. The fixed wiring [ the final circuits, the existing ones ] were installed and certified before you were there....at initial verification of the , then , new installation.


Yes, you have to do some verification when re-energising the circuits by virtue of DB replacement. But enough to demonstrate that things are no less safe than when you started.  That can be done in many ways..e.g..you may have an EICR as a point of reference....compare before and after and/or sample live tests before change...then a sample wander R2 dead before energising new DB]. The circuit schedules and inspection schedules [ model forms] are one size fits all. You do not have to fill them all in if some are N/A to what you have installed.


The EIC is not really a good fit for a DB change, but that is all there is.


There should be care that you do not take on any responsibility for stuff you did not actually put in [ the cables]. A statement in the extents along the lines of "no new wiring or circuits" will certainly help.

Yes BS7671 makes a presumption that all is perfect in wiring land and that everything was initially new installed to standard and maintained as such throughout its life. But that never really happens, except in more monitored situations, like your Hospital for instance. Even then, some stuff will always be missed and there will always be errors that may or may not be picked up later. You can only do what is practicable under the circumstances.
