I rely on the following to prove my electrical connections:

  • Having a Torque Screwdriver for show and occasionally use it as the fancy takes me

There appears to be anecdotal evidence from recent threads and the interminable debate regarding BS 7671 Amd 3 and the non-combustible CU thing that Neutral connections are the source of many overheating incidents that in some cases lead to fires. There is nothing currently in BS 7671 or other Codes of Practice that require the integrity of the Line-Neutral circuit to be proven

- What is your experience?

- Do you carry out any tests to ensure that the joints that you produce are always 'sound'?

- Does your experience and 'Mk 1, Self-Calibrating' right or left wrist do the right job every time?

- Will you share your photos of the results of dry joint resistive heating and its aftermath if any?

Discuss!

The neutral bars that seem to be generic on some boards seem to have very tight threaded screws , so much that I have had to use a large flat driver to get them to tighten , if you use a torque driver it would be useless in this situation , you have to really pull them to check that the screw has properly held the wire , doing an e/loop or Rcd test would not always show the loose neutral, I am in favour of re checking all connections after the board has been in use and like to re check the following day when re wiring etc ...
 
Just put a high load on end of circuit and use your thermal camera to check all joints. Job done no need for torque screw drivers or metal consumer units then
