Maybe someone can post an example of a panel schedule.
Okie-dokie!

08:00 - 08:30 .......... Install panel
08:30 - 08:45 .......... Remove KO's, install cable clamps
08:45 - 09:00 .......... Insert cables in clamps
09:00 - 09:30 .......... Make up EGC's
09:30 - 10:00 .......... Make up grounded conductors
10:00 - 10:30 .......... Morning break time
10:30 - 10:45 .......... Install breakers
10:45 - 11:15 .......... Make up ungrounded conductors
11:15 - 11:30 .......... Install panel front cover
11:30 - 12:00 .......... Make up panel label
12:00 - 12:30 .......... Lunch time

How's that? All done by lunch! :)

Still tarp as a shack. :grin:

Please see the attached file.
Nice panel schedule.

However, it appears to have an excessive number of conduits used. 29, 20mm? (3/4") conduits outgoing for 2-wire w/ground circuits (assuming ckt#16 is a typo). Is there a means to combine into lesser number of conduits, or is this how it is spec'd by the USACE? Or does one simply ignore the implication and refer to an electrical floor plan?

oh, good point. But in design we have to show condiut for each branch in interior design. But in implementation

If the two, three or four branch come in the same path. We use NEC chapter 9 number of wire per condiut. The maximum size for interior distribution we can use is 2 inch and it has capacity of 28 or 30 wire or so.

In this way, number of condiut can be reduced.

That being the case, I believe there should be a "footnote" to that effect on the schedule.

yeah,
the right way is to draw 3D shop drawing to show everything practically. But they are very large projects and very short time, so it is not possible for us.

Eventhough, I learned some programs to draw 3D very fast like Sketchup Pro7 and 3D Hope Designing.

But again, due to short time of projects we could not find time to do it.
