Electrical Testing

Former Community Member

When coding any consumer unit or switchgear with a combustible (plastic) enclosure only when it is located under a wooden staircase or within a sole route of escape, a C3 is recommended. 


Does this recommendation signify that the overall rating of the install be satisfactory or unsatisfactory? 


I have been ticking Unsatisfactory for the general condition of the installation (in terms of electrical safety) AND the overall assessment of the installation in terms of its continued use! 


Is wrong wrong of me? Even though everything is perfect with results and the installation?

    Here is the note referred to above;

    "9. Where an observation requires further investigation (FI) because the inspection has revealed an apparent deficiency which could not, owing to the extent or limitations of the inspection, be fully identified and further investigation may reveal a code C1 or C2 item, this should be recorded within Section K, given the code FI and marked as unsatisfactory in Section E."


    So only if it may reveal a C1 or C2 code. If we know that the FI can only reveal a C3 code then it should be marked "satisfactory" along with the FI. Only example i can think of would be an FI for seeing if cables in trunking were adequately supported to prevent premature collapse. 

    In searching for a suitable C3 for the above i found this best practice guide bpg4-1.pdf (electricalsafetyfirst.org.uk) which says C3 for plastic CU under stairs or in escape route and no coding if not under stairs or in escape route.
