WHAT IS THE THUMBRULE FOR FINDING OUT THE CURRENT CAPICITY
OF A COPPER WIRE?? 2.5, 4, 6MM SQUARE ETC...
Answer Posted / uttam dutta
cURRENT CARRYING CAPACITY NOT ONLY DEPENDS ON THE CROSS
SECTION OF THE COPPER WIRE, IT ALSO GREATLY DEPENDS UPON
THE TYPE AND THICKNESS OF THE INSULATION, ONE MORE FACTOR
IS CORE OF THE CABLE, IE SINGLE CORE OR MULTICORE.
cONSIDERING ALL THIS FATORS STRICTLY IT CAN BE SAID 1 SQ.
MM COPPER CABLE CAN BEAR MAX.11 AMP SAFELY CONTENIOULY AND
2.R CAN BEAR 19 AMP . 4 SQ MM CAN BEAR 26 AMP. SOME TIME
THIS MAY VARY LITTLE DEPENDING UPON MAKE.

which type of stability limit is higher,steady state or transient? why?
why do we measure VIBRATION in -24vdc and why we adjust gap voltage -9vdc to 10-vdc? i am trying to get this information since 5 years, yet i haven't get reliable answer, i hope i can get from you.
can we use CBCT in neutral of solidly grounded transformer? in place of three phases we can pass only one phase which decreases the size of CBCT?
How to calculate the size of earth cable to earth the neutral of UPS ?
True or false question. 1.The fuse provide phase and neutral 2.power loss in electrical circuit can take place in (resistance or inductance or capacitance). 3.two phase system each phase has separated by a phase difference of (90 or 180 or 270 or 45). 4.3 phase balanced star connected load neutral current shall be (line current or phase current or zero or unity)
