Conductor strands missing!

[the blur]

You consider the cut out on the primary side of the POT feeder protection ??
The POT is probably designed to supply 4 houses.

I am soomewhat surprised by the general response. IMNSHO when you have half the strands missing the current rating of that cable is reduced by half. If your feeder protection is sized for a 4/0 cable then the missing strands would result in inproper protection of the feeder. (I don't know how could you legally size 'reduced' protection since the only size you can take into consdieration is the one that is printed on the conductor jacket, you can't just 'determine' that the missing half strands result in a, say, 2/0 cable.)

Total area of 4/0 is 211600 circular mills. Half of that is just a little more than the area of 1/0.

There is probably an odd number of strands, 19 is typical, so you can not have half of them gone without splitting one strand

I was under the impression the OP knew that it was wrong to cut strands and knew of the risk of overheating and fire, but wanted to know if there were other problems that might have occurred due to the cut strands.

It's a hack install, but I'm with some of the others point of view, the NEC is way overkill as far as residential services are concerned...
