what would the amperage rating be for the following installations 600v 3p3w service entrance
senerio A: 3 - 750 mcm aluminum corflex buried 36 inches below grade in sand spaced 8 " apart.
senerio B: 3 - 750 mcm run overhead spaced a cable diameter apart (FREE AIR RATING)
in both cases sheath currents have been eliminated.
Cables terminate in a 600 amp 80% duty rated fused disconnect switch.
what is the maximum continuous load rating for
these installations.
what is the maximum non continuous load rating
for these installations.
Thanks Nic
