Single line diagram Puns

I’m submitting a permit to my local office for a wall charger. I’ve done all the electrical load calculations and drawing schematics but I’m stumped on the single-line diagram. I can’t seem to find an example of one that’s not overly complicated. Most seem to be for larger EVCS stations in public lots. The Tesla wall charger is already installed in my garage for my personal use.

Any help is appreciated.

Probably a dumb question, but trying to figure out how to read this single line diagram and I'm seeing this along a existing path:

2"C-4#1/0

If you could explain how to read this, I'd be very grateful.

I had a licensed electrician install a 14-50 for charging my Leaf.

I need to get it permitted and they are nowhere to be found.

50A breaker 6 gauge wire 14-50 outlet

Does anyone know what a single line diagram of this would look like?

Thanks?

So I came across a mentality that seems to be common in my field (Union Telecomm Technician) regarding construction prints for wiring, and I want to know what people on here think.

How important is the Single Line Diagram in cabling prints? Is it necessary if you have a routing layout/floorplan and a punchlist? My coworkers, foreman, and the IT guys for the data center we are working all refer to it as the "cover page" and say it doesn't include any information that you can't figure out with the punch list.

My thought is that it's probably the most important part of the print because it lets you know what you should be looking for on the routing print and punchlist and is probably the easiest way to preemptively notice discrepancies and mistakes in the print as a whole.

I looking for an efficient means to draw single line ductwork and piping diagrams using revit. Our company currently uses details lines but seems so inefficient. Is there another means?

Is there an actual "proper" way to create an electrical single line diagram in Revit. So far we don't even bother and just do it in AutoCAD.

Hello everyone,

I am trying to find a way to fill in the area in between two line diagrams.Below an example of a what i'd like to show:

The lines represent measured temperature per day, maximum and minimum. The gray area is an average of these temperatures.

I can't find a way to create such an area.

The point of this is creating a cleaner looking average temperature line over the past 5 years. Otherwise the graph would start to look something like this:

In short:

I need to find a way to plot an area in my line diagrams given a lower Y value and upper Y value for X.

UPDATE

So, just a small update.
Below the end result:

So I just started the third year of my apprenticeship, later this year we will be doing control work at trade school. This is something that I am interested in and am going to do an extra course on PLCs next year.

Its not a course requirement that the drawings be done on a computer, but Id like to go the extra mile and learn how to use a CAD like program. Do you guys have any recommendations of reasonably cheap or free programs that I could use? And possible some reading / learning material?

Im in Australia if it matters Thankyou!
