Correction for operating temperature

lyledunn

Is the correction factor for thermal insulation deliberately omitted? Page 429 BS7671

    Interesting question ... I'll have to have a ponder. (Although my initial suspicion is that the formula might pre-date the introduction of Ci. As for why the correction factors are in there at all, maybe it's down to comparing Ib with It - the correction factors having being originally applied to Ib before selecting It and somehow having to undo that)
