Wire size table

Wire size table

This is a table combined of American Wire Gauge AWG (Chassis Wiring, single free hanging wire) table and the European standards for machine wiring at +40 oC, EN 60204-1.

    NZ wiring as per British standard or American standard for domestic wiring please clarified for 50 Hz,OR 60 Hz

  3. Mads Barnkob says:

    Hi Cyril, European standard is for 50 Hz and American standards for 60 Hz.

    Kind regards

    Good idea but a bit crippled implementation…
    Why are so many empty cells in this table for amperage and how is one suppose to know from where to take the value for such an empty cell (ie from the cell above or the one below)?
    For example, 1.45 mm diameter should it be 16.1 A or 22A?

    Hi Lian

    I updated the table with AWG current rating values, but as you can see, the European and American does not scale even, so its up to how conservative you want to design which rating you will use, it is afterall just a matter of how much temperature rise you will allow 🙂

    You can not just pick a value up or downwards from another gauge wire.

    Kind regards
    Mads
