1 Square Wire, 1.5 Square Wire, 2.5 Square Wire, 4 Square Wire, 6 Square Wire, Etc., So How Many Watts Can These Wires Carry? That's What People Are Concerned About.

1： 1 square wire can load how many watts

An electrician's common "rule of thumb" : as long as copper conductor wire, per square millimeter cross-sectional area can safely through 4--5A rated current; In 220V single-phase circuit, the current is about 4.5a for every 1KW power; In 380V three-phase balanced circuit, every 1KW power, its current is about 2A. These values above, usable physics computation formula calculates the result that comes down is very close, so electrician is in the job, for not to remember those "trival" computation formula, it is ok to remember these. So according to this algorithm we know: every 1 square millimeter cross-sectional area of copper core wire, if used in 220V single-phase circuit, can safely carry the current through 1KW load; If used in a three-phase balanced load (such as an electric motor) circuit, it can safely carry the current through a 2.5KW load.

2： 1.5 square wire can load how many watts

If the power cable is copper core wire, first, the maximum allowable working current of open line installation is 20A, that is, 4400 watts; The second is the concealed steel pipe, the current is 16A, the power is 3520 watts; Third, PVC pipe is hidden, the current is 14A, so the power is 3000 watts.

3： 2.5 square wire can load how many watts

2.5 square wires by pouring kilowatt power, gb GB4706.1-1992/1998 wire load current value, copper wire 2.5 square millimeters 16A to 25A about 5500 watts, Aluminum core wire 2.5 square mm 13A ~ 20A about 4400 watts 220VAC voltage for a long time not more than 10A the most standard most of the time not more than 15A is safe.

4：  4 square wire can load how many watts

Single-phase power supply of 1KW is about 4.5a, 8KW is about 36A. 4 square wire (single root of plastic copper wire) carrying capacity is about 30A, smaller, change 6 square line (single run power supply). You must change your watch and switch to larger ones. You don't have to do that. 4KW is the minimum. How many kilowatts of electricity can be poured down by 4 square wires depending on whether you use 220v in a home or 380v in a factory. If 4 square wires of 220 can load 6 to 8 kilowatts.

5： 6 square wire can load how many watts

How many kilowatts can six square wires carry? The diameter of the power line is not directly related to the power transmitted, and generally six square wires are more than enough for air conditioning. The maintenance power supply on the construction site generally uses 10x6+1x4 cable. As for the current intensity, according to my construction experience, this kind of cable is generally controlled by 63A air switch. Six square aluminum wires can carry up to 6 kilowatts, and six square copper wires can carry up to 10 kilowatts.
