BARRY MAY: THE CUSTOMER COMPLAINED THAT THE BATHROOM LIGHTS WERE FLICKERING WHEN THE EXTRACTOR FAN WAS ON. WE REMOVED THE FAN AND THIS MESS FELL OUT…!
Some things just never seem to change, which is very frustrating. There are so many defects here that it’s tough to know where to start, so I’ll try and group the various issues together where I can:
1. Terminations and single insulation not taken into an enclosure are a problem as there is no adequate mechanical protection. There are a few of those issues in the photo.
2. Terminations not adequately supported may cause strain on them, leading to loose connections and possible arc faults and fires. This would explain the intermittent flickering operation reported by the Client.
3. Cpc is not taken to each accessory and point in a circuit, which means there is no shock protection after the first accessory. We can see where the cpc has been intentionally cut and left out of the way on the 3-core flex.
4. The termination of the cpcs in some of the flat twin and earth cables is not adequate. Twisting cpcs together is neither a reliable method to ensure adequate termination nor will it aid in periodic inspection and maintenance.
5. I can’t see from the photo if there is any access to live parts where the terminal connectors are used. A couple of them seem to have multiple conductors in them, which may or may not give rise to access to live parts.
The shameful thing here is that the work seems to have been a recent install, which means the low level of skills shown is likely to be found in other installations by the same installer. This type of workmanship is only ever going to receive an unsatisfactory result on an EICR.
