Sq mm stands for square millimeter, a unit of area measurement.

• Sq mm is a unit of measurement used to quantify the area of a two-dimensional space.

• It is equal to the area of a square with sides measuring 1 millimeter each.

• Commonly used in engineering and construction for measuring small areas.

• Example: A sheet of paper may have dimensions of 210 mm x 297 mm, which is equivalent to 62370 sq mm.

The number of leads in sqmm wire depends on the wire gauge and its application.

• The number of leads in a sqmm wire can range from 1 to over 1000 depending on the wire gauge and its application.

• For example, a 1 sqmm wire may have a single lead, while a 1000 sqmm wire may have over 1000 leads.

• The number of leads in a wire can also depend on whether it is a single-core or multi-core wire.

• In general, the larger the wire gau...read more

Sizes of cables and db box are determined by the electrical load and distance of the circuit.

• The size of the cable is determined by the electrical load and the distance of the circuit.

• The size of the distribution board (db) box is determined by the number of circuits and the size of the cables.

• The cable size is usually specified in square millimeters (mm²) or American Wire Gauge (AWG).
