    Something I did for fun many years ago.

    Looks like that took some time to draw up. Thanks very much for sharing it! Now, just to modify it for the split (half-size) breakers and my layout. I will use this as the basis for a modified single line diagram, submit the plan package and then let them tell me what they want changed or added.

  2. Thanks Renerabbit for the good advice! Due to the Wuhan Virus the Permit Office is closed; not even answering the phones, so I'll have to wait to talk with them - electronic submitals only. This is my second owner-builder major remodel project. I've done lots of work for other contractors, including electrical, but getting the permits is way harder than just doing the remodel!

  3. City of Tucson. From


    Electrical Requirements:

     Electrical Plans Fully dimensioned floor plan showing location and assigned circuit numbers of all outlets, luminaires, switches, appliances, panels, motors, disconnects, electrical and HVAC equipment. All outlets should indicate panel name or number

     One Line Diagram Include panel and feeder breaker ratings

     Panel Schedule Include panel numbers, voltage, phasing, location, bus size, circuit number, breaker sizing, and wire sizing.

     Lighting and Outdoor Lighting Code Compliance with the PC/COT Outdoor lightning code to include light budget calculations and considerations



  4. My building permit department requires a lot more info than what C.A. currently provides, such as electrical panel schedule(s), load calculations and single line electrical drawings. They do not provide any samples, and I have not yet found any examples in the C.A. sample plans.


    I would appreciate learning about any templates or other resources people use to supplement C.A. and provide this kind of info on the permit layout sheets.


    I assume you just create it in Excel and import it? I've found some templates:



    Also, there is very little info on the web about residential single line electrical drawings and, not being an EE, I only need main panel and sub-panel(s) - not all the upstream transformers, etc.


    i know there are many very experienced designers here that probably have solved this problem long ago, and I would really appreciate it If I didn't have to "re-invent the wheel" so pretty please will you share your experience and/or links to to good resources? 


    Perhaps this is something that might be added to a future version of C.A.?

  5. I'm trying to create the roof / cathedral ceilings for an as-built of a rectangular house where the north and south exterior walls are 8' tall and 28' apart, and there is a parallel load bearing interior wall that is off-set from the mid line by 3.5' and is 9'-5" tall. There is no ridge beam, the rafters simply sit on this interior load bearing wall (and opposite pairs of rafters are off-set so they sit next to each other and are nailed together). The ceiling drywall is simply screwed to the underside of the rafters (which are 2x8s). I don't know the roof pitch, only the heights of the walls and the distance between them. Is there a way to get the roof planes (with the two different unknown pitches) to sit on both the exterior and the interior walls?


    I thought maybe if I lock the ridge height I could pivot the roof plane down so that it set on the exterior walls, but I don't see a way to do that? Trying to lock to the baseline height results in a mismatched roof elevation at the ridge given the off-set. Is there a way to pivot the roof planes?
