It is metric that is used in the European standard of wire measurement.
2.5 sq mm or 4.Sq mm coil is used for breaker in industries
10 amps
It will taken 8 amps <<>> The conversion of 2.5 sq mm wire to AWG is equal to a #12 wire. The ampacity of a #12 copper wire with an insulation factor of 90 degrees C is 20 amps.
A 35 sq mm copper wire with an insulation factor of 75 or 90 degrees C is rated at 115 and 120 amps respectively.
Lapp is the name of the manufacturer, but this is a 3-wire cable with conductors of 4 sq. mm. in size.
For 3-core twin and earth cables up to 4 sq mm with reasonable air circulation, allow 8 amps per sq mm for copper and 5 amps per sq mm for aluminium. For permanent installations with high usage per day, use 4 amps per sq mm.
Assuming the allowed volt drop is 5% or 5.5 volts, the wire resistance has to be 5.5/15 ohms or less, 0.367 ohms. The total length of wire is 600 metres so the resistance per metre is 0.00061 ohms. 1 sq-mm copper wire has a resistance of 0.0168 ohms/metre so you need wire with a size of 0.0168/0.00061 sq-mm, or 27.5 sq-mm. The next size up is 35 sq-mm in European cable size, or #2 AWG in America.
4amps can pass in 1sqmm of wire max it is universal. In the UK 1 sq. mm wire can take 10 amps max according to tables. Cables that become warm in use should be replaced by a thicker gauge.
20 sq cm = 20*100 sq mm = 2000 sq mm
The wire can be as big as you want to carry 6 amps. As a comparison, the smallest home wiring power circuit uses a #14 size wire and it is rated for 15 amps. In the UK a wire of 0.75 sq. mm is rated at 6 amps for portable appliances with occasional use. For a permanent installation a cable of 1 sq. mm. or more should be used. House wiring uses 2.5 sq. mm cable in a ring circuit to supply power sockets.
It can carry upto 100 Ampere.
The current-carrying capacity of a 6 sq mm wire depends on various factors, including the type of insulation, installation conditions, and ambient temperature. Generally, a 6 sq mm copper wire can safely carry around 30 to 40 amps for standard applications. However, it's important to consult local electrical codes and guidelines for specific installations to ensure safety and compliance.
