hmmmm   how did I do it ???

first off  I ran # 4 wire from the main box to the shop thru 1.5" grey PVC 
( 2 120 VAC system) to the shop for 240VAC ( opposed phase 120) ( well that 
makes sence;)  ) along with a nuetral and a ground ( 4 wire run)  and I 
placed an extra ground at the entry point at the shop for extra measure.... 
plus I have 2 more ground rods for the T - Coil for RF ground ...  But here 
is the clencher... I  tapped into the main box AT the main input to the 
fuse system of the house... ( in other words... there is a direct feed from 
the mains to the shop) But ...  I do have a 70A breaker in the shop in case 
the system goes to ground or fault ( so I am protected in that sence) 
...  but then again I am pulling 60+ amps for the T coil too ;) if the 
wires between the main box and shop short ....   HOLY MOLY we got a show to 
watch  ;)

I think the resistance of the  #4 is limiting the current to the shop 
tho...  doubt I'll ever get more than 75A to the shop....
