I am doing work at a building with two 480v services fed from a padmount xfmr.
One set of conductors runs from the xfmr to an end box with a ct cabinet on either side.
The electrician ran 1000 kcmil wire from the padmount to the box to bug to the service conductors. First service is protected by a 600a main breaker. The electrician ran parallel 500 mcm (which he bugged to the 1000 kcmil) into the first ct cabinet which odly enough has 200a ct's.
The second service is protected by a 400a main breaker which also has a ct cabinet with 200a ct's and one set of 500's.
Now this to me is 1000 amps total which is capable (not probable) of being pulled threw those 1000 kcmil conductors! 1000 kcmil is good according to code for a little over 600a. How did this pass inspection and why would the power co energize this?
