So I got this surge test I need to do some research on and need some help as my electrical background minimal.
The test i'm working to setup is as follows: I have to surge test this big switch (just shoot 12V DC, 2000 AMP to the switch terminal for 1 second)
We only have a 500 amp power supply but we got tons of 300 Watt load banks From what I understand, I can connect the 500 amp power supply to one load bank(master) and than chain a bunch of other load banks (slave) in parallel to add up the currents until I get 2000 AMPs.
The final load bank at the end of my parallel chain positive lead will connect to the positive terminal on the switch and the first load bank (master) negative lead will connect to the ground terminal on the switch?
Am I doing this correctly? I believe my math is correct, that I can use my 12VDC/500A power supply to create a 12VDC/2000A output via chaining x amount of load banks in parallel I'm not sure if my wiring is correct thou..also how will the resistance from the wires affect my output? I believe i need a 3/0 AWG wire at the minimum..(probably safer to go with something even bigger)
Any help or suggestions for better methodology would be appreciated! Thank you!
