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 xaim tuaj yeem thauj khoom ntau npaum li cas 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 xaim tuaj yeem thauj tau pes tsawg watts

Yog hais tias lub hwj chim cable yog tooj liab tub ntxhais hlau, ua ntej, qhov siab tshaj plaws tso cai ua hauj lwm tam sim no ntawm qhib kab installation yog 20A, uas yog, 4400 watts; Qhov thib ob yog cov yeeb nkab steel zais, tam sim no yog 16A, lub zog yog 3520 watts; Thib peb, PVC yeeb nkab yog muab zais, tam sim no yog 14A, yog li lub zog yog 3000 watts.

3: 2.5 square xaim tuaj yeem thauj tau pes tsawg watts

2.5 square xov hlau los ntawm pouring kilowatt zog, gb GB4706.1-1992/1998 xaim load tam sim no tus nqi, tooj liab hlau 2.5 square millimeters 16A txog 25A txog 5500 watts, Aluminium tub ntxhais hlau 2.5 square mm 13A 20A txog 4200 awatt voltage ntev tsis ntau tshaj 10A feem ntau tus qauv feem ntau tsis ntau tshaj 15A yog kev nyab xeeb.

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 hlau tuaj yeem thauj khoom ntau npaum li cas watts

Muaj pes tsawg kilowatts tuaj yeem nqa mus rau square xaim? Txoj kab uas hla ntawm lub hwj chim kab tsis ncaj qha cuam tshuam rau lub zog xa hluav taws xob, thiab feem ntau yog rau lub square xov hlau yog ntau tshaj li qhov txaus rau cua txias. Kev saib xyuas lub zog ntawm qhov chaw tsim kho feem ntau siv 10x6 ntxiv rau 1x4 cable. Raws li qhov kev siv tam sim no, raws li kuv qhov kev tsim kho, hom kab no feem ntau tswj los ntawm 63A cua hloov. Rau square txhuas hlau tuaj yeem nqa mus txog 6 kilowatts, thiab rau square tooj liab xaim tuaj yeem nqa mus txog 10 kilowatts.
