Hi all, my father in law has a rental property that was completely rewired and with new split load CU five years ago. The installation is now due an inspection. Will the fact that the CU is plastic constitute a "fail"?
The 651.2 expects us to look for danger and report, eg primary protection, fire and heat from a defect, ratings of cables CPDs etc, monitoring devices, deterioration, and defects which may give rise to danger. Then the notes.
Generic list for inspection Appedix 6
Previous editions fine unless they are unsafe.
My comment is there has never been any indication from anywhere that a plastic CU is inherently dangerous, it only may become a fire risk if the terminals are not tight leading to excessive heating. Thus my remark above that the terminals should be inspected for heating and tightness and corrected if loose. (I didn't put it in quite as many words).
BS7671 does not say plastic CUs are dangerous, most are not. It does not say they should be replaced. It does not say that existing CUs are non-compliant.
