Changeover mess


 An assembly to be proud of!  The wiring down to the meter is just a bit of HO7RNF with the outer sheath stripped back. The door pulls open with a simple thumb-turn. 
It is an automatic start up which kicks in when the load exceeds some pre-set value. It disconnects the mains to a business venture at the rear of a farm. Of course there is a delay and so tills, computers, cctv etc are all interrupted. 
Installed in the attached garage of the dwelling. Speculating that this was moonlighting by someone who messes with gen sets but has never touch base with 7671!

  • Or buy a padlock.

    The innards look like they might just meet IP2X or IPXXB - if so it would seem to meet the requirements of 412.2.2.3 even if the door can be opened without the use of a key or tool.

    what is that great tangle of shielded twin ?)

    I was wondering that too (I couldn't quite see what it would connect to...) - maybe it's FELV?

    This is a photo from one of our recent periodic inspections for which I was out doing QA.  It will end up as part of a portfolio of images that I will pop up on the screen during my 2391 classes. 
    It will serve to demonstrate that the initial verification process is a tad easier than assessing whether an installation is safe for continued use, which is the key tenet of periodic verification.

    My guy seems to have opened the enclosure, witnessed the evident mess and gone for his code two gun. I am not saying he is wrong, but he failed to point out the reason for his concerns. 

    I think that the client deserves a clear explanation for the observations and associated codes arising from any professional periodic inspections where EAW Regs apply.
    The code two given  for the inner cores of the HO7RNF cable being exposed might be just an obvious one-liner for the inspector but I require it to be explained. It would seem that most guys have difficulty in presenting a clear summary of their findings, but it isn’t good enough to simply tut and say “that’s a code 2 mate!”

    The tangle of shielded conductors are part of a multi-core cable that runs to the generator control panel to instruct a start.

    so, it really is being put in for a 'spot the hazard' competition....

    But I understand the uncertainty - not  to regs, for certain,  but what to code it, as it is poor work, but maybe not an immediate danger, and maybe even borderline for a very stern C3 if the door actually locked,  - mind you what is protecting the white singles - is any of that just on a company fuse?

    And  ideal as an example of something  less "textbook" to make the trainees think about what they may one day encounter.

    I spend a couple of hours towards the end of the course just to engender a bit of debate and discussion on the coding concept. It is interesting to see how different the candidates determinations can be. I have to be careful not to supplant my own views over those promulgated by ESF on the subject. Whilst there is much common ground, I often find myself oceans apart with them on occasions. 
    The on-line City and Guilds exam could have several questions on “what code” given a certain scenario. They seem to stick rigidly to what it says in ESF Best Practice Guide 4. Unlike the written exams of old, that our dear friend David Stone would laud, there is no room for logical expansion of one’s opinions in a multiple choice paper!
