    To unprotect the excel sheet
    Alt+F11
    view (Alt+v)
    code (F7)
    paste the following in the white space
    Sub PasswordBreaker()
    ‘Breaks worksheet password protection.
    Dim i As Integer, j As Integer, k As Integer
    Dim l As Integer, m As Integer, n As Integer
    Dim i1 As Integer, i2 As Integer, i3 As Integer

    In case of Busbar voltage drop calculation you take Resistance=0.005 ohm and reactance=0.011 ohm . what is the reference of these values. have any international code ? also how can i get a cable resistance and reactance ?

    please advise and calculate, i have 5x1250Amps,.8pf, 220v gensets, synch to a common busbar, and two outgoing CB’s of 2500A, what will be the main busbar rating.

    IN BUSBAR TRUNKING SYSTEM HOW DO YOU CALCULATE THE KA RATING OF THE BUSBAR. FOR EXAMPLE IF CUSTOMER ASKS US TO GIVE 50KA WITH 50x10mm ALLUMINIUM OR COPPER BUSBAR WHAT IS THE FORMULA WE HAVE TO APPLY PLEASE SOME ONE WHO KNOWS ABOUT HIS GUIDE ME

      Customer normally shouldn’t ask you this, but to tell you the ratings of loads, so you can calculate the CBs in incomers and outgoing cubicles, as well as rating of main horizonal busbars. When you have all these information, you can calculate short curcuit withstand current on busbars.

    I entered the results but I didn’t know what is sin(phi) so i put it =0
    and the results below:
    ——————————————-
    Selected BusBar is Correct
    3.92 (Within Limit)
    ———————————————
    What is the size of the bus bar ?
