How do you calculate cable size?

Divide the voltage running through the cable by your target current. If, for instance, 120 volts will act on the cable, and you want 30 amps to run through it: 120 / 30 = 4. This is your target resistance, measured in ohms. 30,000 x 1.724 x 10^-8 = 0.0005172 ohm sq.

How do you measure 2.5 mm cable?

Cable Selection And cables for sockets on a ring or radial main are normally a 2.5mm cable. This measurement is the cross-sectional area of the individual wires within the cable – the actual area of the exposed face of the wire. The size of the cable should be printed on the sheath.
