Is the failure electrical equipment these days due to poor or rapid build quality with today's JIT culture, poor installation practice, a lack of periodic maintenance or some or all of the factors listed
Most if not all new consumer units have a note with them telling the installer to check the integrity of the terminations within the unit, how many bother or was that the real reason plastic consumer units had a higher failure rate in London as no one checked the factory made connections
Those who think a torque screwdriver is the be all and end all of making a good termination do they use a torque it once option or do they revisit the terminations after 10 - 15 minutes and retorque so the effects of copper and terminal creep are mitigated
Back in the days of my apprenticeship we had a full easter weekend in a small factory checking the terminations of the switchgear and distribution equipment this was done every 2 years and it was surprising how much was needed to retighten some of the terminations after the previous PPM 2 years prior, ok some only took a fraction of a turn but others needed ½ to ¾ of a turn to bring them back to spec
So is it the actual brand that has a problem or do we as electricians and to some extent the end user contribute to the problem with poor installation practice and the customer for not wanting to pay for periodic checks or ongoing maintenance and by maintenance I mean a full check and not a limited EICR inspection.
From what I have seen on some forums some opinions seem to dismiss the EV point as not being part of an EICR, is this because they don't have / won't buy the appropriate test adaptors to do a complete installation inspection is it fair gain to add a limitation to exclude it from an EICR as more and more installations have them installed. When you look at an EV chargepoint it is the most sustained significant load on a domestic installation so does this add to the problem of equipment design
