Two CoCs will be needed; one for the establishment of the emergency supply; and another when the normal supply rom the grid is restored.

Setting up the emergency supply

Before certifying this work; make sure you’ve done a FULL set of tests of your work. DON’T allow urgency to lead you unto skipping this essential part of the work. And preferably keep a copy of the test results.

Disconnection of mains, disconnection of MEN link, and (where required) moving the MEC connection from N-bar to E-bar are all “mains work”; and would normally be classified as “high risk” PEW requiring inspection. However the TB has declared “ the prescribed electrical work carried out to install an emergency generated power supply”  to be “general” PEW. So no inspection required. And this should also apply to installing a N-bar so that the installation has separate N & E bars.

 The CoC and ESC (either separate or combined) for this work must include a statement that the TB has been followed.

  • as always, give a detailed description of the work done
  • cross out the bit on the CoC that states that either Part 1 or Part 2 was complied with
  • write in that the work was done in compliance with the technical Bulletin
  • In the declaration that the work was done ‘lawfully and safely”; consider crossing out the word “lawfully”.

Note:  The TB does NOT suspend the requirement set by the Act to comply with ESRs; nor does it suspend the ESRs requirement to comply with AS/NZS 3000. The TB is official guidance; but it’s not “law” in any way. So declaring that you’ve followed the law, when you’ve actually done something different, is making a false declaration.
