How much load can a 2.5 mm cable take?

how many watts can a 2.5 mm cable take? 2.5 square BV wire, overhead wiring at 20 degrees, 220 volt power supply can be up to 4.4KW. Therefore, a 2.5 square BV wire can be used with a maximum of 4.4 KW.

How do you determine 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 much power does a static caravan need?
