**Calculating kVA Sizes UST**

Can anyone help me by telling how to calculate the Wire Drawing Charges, For example i need a copper wire which has 36 strands, each strand has dia of .285 mm, now i am able to calculate copper rate on LME Basis but after that i need to calculate Wire Drawing Charges for wire size 0.285 mm, as i am outsourcing the Bunched Form Copper, i need to how my supplier is adding up those conversion... I want formula to calculate cable size as per load given in kw & amp.I searched many sites but didn't right answer.Plz reply me asap. My question is whether bellow formula is correct to find bus size for 46kA for 0.5 second & what is RT in bellow formula. formula to calculate the size of busbar to withstand the thermal stresses due to currents with duration of 0.2 sec to 5 sec. Sp = RT( I

Southwire's voltage drop calculator will help determine proper wire size for an electrical circuit based on voltage drop and current carrying capacity Voltage Drop Calculator... 20/07/2008 · At the risk of getting flamed; a good ballpark figure for sizing the wire is 5amps per square mm, so 6mm cable is good for about 30 amps and 2.5mm cable is good for about 12.5 amps. You may need to increase wire size for long runs as voltage drop will come into it. Voltage drop in a cable will increase as the current through the cable increases, if you're running 5 amps through a cable and the

### Online electrical calculator which helps you to calculate the size of copper, aluminium wires in an electrical circuit. Code to add this calci to your website Just copy and paste the below code to your webpage where you want to display this calculator.

- How do you calculate the size of a dynamic braking resistor? To specify the resistor we need to know three things: the energy per stop, the duty cycle and the ohmic value. The first two are usually combined into one variable, the power of the resistor. Power. In an ideal world you calculate the mechanical energy involved in each stop, using one or more of the above formulae. This will be the
- * To calculate wire size, use 12.9 as your K for copper and 21.2 as your K for aluminum. * "L" is the one-way wire length in ft. * "R" is the resistance per 1,000 ft. Use NEC Table 9 for AC wiring. If you have non-linear loads, use the column that helps account for power factor.
- Because its cross-sectional area is machined to such precision, calculating a wire's weight is as simple as multiplying the cross section by the length by the density of the material. Determine the cross-sectional area of the wire's gauge.
