Are there any regulations, rules of thumb, etc. against using 5kv or even 15kv single insulated copper conductors such as transformer jumper lead for 480V circuits in temporary protected installations? I haven't been able to locate anything in the code that inhibits its use.
NEC Table 310.60(C)(69) indicates an ampacity of 695A at 90deg C for a 5KV, 500MCM cable. On a 2000A circuit, one could install 3 conductors per phase instead of 6 if terminated effectively at 90 deg C and installed properly.
