Minor works certificate and testing questions

Hi, I saw written somewhere that when carrying out minor work, you take responsibility for the entire circuit not just the new work? 

Are the tests performed on the whole circuit and all points? Say you install an addition socket on a circuit, do you then continuity test all 10 other sockets, check for missing grommets, shoddy work, bad connections, missing sleeving, and repair all that? 

The minor work certificate doesn't come with the schedule of inspections so I'm guessing it isn't used on minor works and it's more of a ‘quick glance - everything looks OK’ inspection? 

Also, the bonding and RCD requirements - if you were installing the additional socket, and they weren't there, you would have to install all main bonding and fit an RCD / RCBO? And if the main earth was less than 16mm (on a domestic) you would have to install that? 

Would you also have to investigate the if the circuits been installed less than 50mm depth and in zones and so on to see if an RCD was required in that respect?

Ta!

  • The example that I was considering, was a 20 amp circuit in 1.5mm twin with earth that supplies only a cold room refrigeration compressor, rated running current 9.5 amps and protected by a thermal overload relay set at 10 amps.  20 amp fuse was only for short circuit protection.

    Safe and still safe safe after I added a 3 amp fused connection unit for a data logger, with a negligible running current, less than 0.1 amp.
