    NEC and IEC 60346 equivalent

    Good evening folks !

    Im currently reviewing a Project made by Spanish contractors in Mexico (funny isn't it ?),

    These guys used the IEC 60346-5 for their wiring calculations instead of the Mexican nom (The mexican nom is a copy of NEC 2011 so ill just refer as NEC now),
    We are trying to see if they do match,
    As far as I can see temperature derrating is the same on both normatives, yet when you get to 60346 table B52.20 for grouping it gets interesting, link to that table below
    https://www.ti-soft.com/en/support/h.../table-b_52_20

    Correct me if im wrong but what we use for grouping is 310.15 (b)(3)(a), and its totally different for the table used in this project per IEC, and I do not recall something similar in the NEC.

    Have any of you guys come across projects like these where IEC is used instead of NEC?
    Any recommendations

Working...
