The list of wires to be disconnected fit on four sheets. The new wiring schedule fit on four tabloid-sized sheets. Wire checkout took about one day. At the end of the day, we had a list of two pages of deficiencies, mostly these were that a wire went to a new device, but the last jumper to the new electronics was missing. We noted a number of spots where new wires on a terminal block were all out of position by one terminal. We even found a wire that had been misconnected for 30 years.
In a couple of spots we had to hunt for wires disconnected early in the upgrade. Each of these wires took about an hour to find and put back.
Some of these deficiencies were due to the vendor, the consulting engineer and the electrician. Some deficiencies were missed items, and some were surprises. No show stoppers.
Keep in mind the drive is still not making any profit for anyone.
I will let you know how the commissioning goes in a future blog post.
