    Outdoor t&e - EICR fault code?

    Hi all The subject says it all - there's a lot of outside exposed clipped t&e out there with all the attendant physical protection and UV issues. Question is - should it have a fault code on a report? I guess it would be a C3 at most, but should it feature at all? Cheers
