Re: Certification Strictly, if you're going 'by the book' then the EIC will need to be signed by the other sparks as well, as it is supposed to be signed by the installation designers, installers and testers.
Obviously this may not be 100% practical if they didn't even hang around to connect stuff up, but realise that if you sign off on it then it's gonna be your arse on the line if something does go wrong. Obviously the T&I should flag up any issues like continuity, insulation resistance, Zs etc. but that doesn't mean there isn't horrors lurking beneath |
