Common Uses for 1.5 mm² Wire

Metric vs AWG

The IEC 60228 metric system specifies wire by cross-sectional area in mm², while AWG uses a gauge number system. The closest AWG equivalent to 1.5 mm² is 15 AWG, 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.
