I would like to know if there is a chart that lists the maximum surge current of AWG wires. I am close to finishing my 4000 Joule 1600V capacitor defibrillator and would be inconvenienced if the wires explode/melt away.
Do you know the estimated discharge time? A joule is one watt second. If you dump it all in one second that the same as a 14.4 mega watt load at 1600 volts or about 9000 amps for one second.
Two 4/0 welding cables can take that kind of burst. they can hold a continuous duty 1000 amp submerged arc welder without trouble. Even with 20 KA peaks I doubt you would bother them one bit.

16 gauge copper wire: Tmelt = 1083, Area = 2581 circ mil, Time = 5 sec, Tamb = 25
E= Area in CM
B = Tmelt - Tamb in deg. C
D = 234-Tambient in deg. C
T= time in seconds.
So, E = 2581, B= 1058, D=209, T=5
Then
Ifuse = E* SQRT {<LOG[(B/D)+1]>/(T*33)}
Ifuse = 2581* SQRT {<LOG[(1058/210)+1]>/165}
Ifuse = 2581* SQRT {<LOG(6.04)>/165}
Ifuse = 2581* SQRT {0.781/165}
Ifuse = 2581* SQRT {.00473}
Ifuse = 2581* 0.0688
Ifuse = 178A
