BRENDAN O’CONNOR: THE CUSTOMER WANTED A SECOND OPINION ON A BOARD CHANGE. “THE WORST DIY JOB EVER” WAS A FAIR OPINON, DON’T YOU THINK?
When electricians are called to site and come across poor standards of installation work carried out by householders this does cause a great deal of frustration (and rightly so).
There is a lack of protection from the sharp metal edges of the consumer unit knockouts for the meter tails and other final circuits, Regulations 522.8.5 and 526.7 have requirements for mechanical protection and support of cables and terminations.
The termination of the meter tails to the main switch has resulted in exposed copper where either the cable did not have sufficient length to re-terminate or just another poor method of installation.
The unused entry hole in the base of the consumer unit and the lack of insulation for the copper busbar allows B access to live parts.
The use of a black conductor for the earthing conductor shows a lack of knowledge of the requirements for BS 7671, and this also appears to be undersized.
Therefore, the classification code would be a C1, Danger present, risk of injury, immediate remedial action required due to the risk of contact with live parts.
