The IEC 60228 metric system specifies wire by cross-sectional area in mm², while AWG uses a gauge number system. The closest North American equivalent to 150 mm² is 300 kcmil, but they are not exactly the same size.
Metric sizes are standard in Europe, Asia, Australia, and most countries outside North America. When replacing or matching wire between systems, always verify the actual cross-sectional area rather than relying on approximate equivalents.
150 mm² metric wire (IEC 60228) is rated 240A (copper, IEC 60364-5-52 method A1, PVC, 2 loaded) and is commonly used for very heavy industrial loads, primary distribution cables, power utility connections. Its diameter is 13.82 mm. The closest AWG equivalent is 300 kcmil.
150 mm² wire is approximately equivalent to 300 kcmil in the American Wire Gauge system. Note that IEC and AWG sizes do not align exactly — when substituting, choose the AWG size with equal or greater cross-sectional area to ensure adequate ampacity.
