I looked at a job and in the electrical room there was a large wireway that fed 4 meters that each had a disconnect that fed xfmr then to a lease space.
1 had only the disconnect 480v 400amp, meter to line side of disconnect. Where working in the bldg and ask me to see if I can make use of the spare disconnect. I only glanced at the terminations in the disconnect. After I left I asked myself why was there a grounding bushing on the disconnect side bonded to neutral, must mean its a tap of the service but the boding jumper that bondes the neutral or ground to the enclosure was still in the package. No GES of any kind directly to the meter or disconnect
All holes from wireway to disconnect looked drilled and it was all piped. I know if its a service the grounding bushing is the norm + the volts to ground although the holes were drilled. I realize its all grounded but why no bonding strap. Most AHJ would fail this.
Ill check more when I go back but im not sure if this is service entrance or subpanel.
