For a system that is being built to IEC-60947, what color should wire be that is carrying foreign voltage that will not be turned off by the enclosure's main disconnect?
I found a chart with the other IEC color codes but it doesn't list "foreign voltage."
In the USA, it's orange when complying...
This is not really an AutoCAD question but one on updating drawings.
We do mainly electrical control drawings and I'm used to putting revision # in the title block with a brief description and date of the change. Then somewhere on the drawing a numbered revision triangle would be shown near...
My settings crashed in AutoCAD Electrical 2014 yesterday and I got everything back except for when I have a project open it used to display a "tab" for each drawing that I have open just underneath the ribbon bar.
It made it real easy to switch between drawings, etc.
Does anyone know how to get...
How do I add another wire layer in an AutoCAD 2013 Electrical Project?
I need the new wire layer to become part of the PROJECT and not just part of a single drawing. If the wire layer is properly added to the Project shouldn't it show up as a choice in the other drawings within that same...
Would someone be able to tell me what this means on a specification for relay contacts: "......10 amp make, 1.5 amp break."
Is this the same thing as saying the contacts need to be rated for a 10 amp continuous load?
The rest of the relay spec seems clear, coils may be either 120VAC or 24VDC...
I'm running AutoCAD2008 on Windows XP and have loaded the latest
service packs, etc.
AutoCAD had been running fine until just a minute ago and now the "Open" command & icon do not work properly. When I click on either the "Open" icon or do "File\Open" the window does not pop up showing all of...
Here is an AutoCAD for dummie question:
Why are some drawings created in under the "Model" tab and others in the "Layout1" tab?
I edit a lot of drawings but am by no means an expert. I am having a difficult time editing or manipulating drawings done in the "Layout1" tab.
I am using AutoCAD...
What does the the term "proceed at risk" generally mean in a construction project?
Yesterday in a meeting there was a discussion about a proposed change (adding some operator stations). The end user has not approved this yet but GC said it we should proceed at risk.
At who's risk (mine, GC...
Today when I called up AutoCAD the Windows Menu/Toolbar was not there. The one with File/Edit/Insert/Format/etc. across the very top of the screen.
How do I get it back?
My regular AutoCAD toolbars are still present.
It was there yesterday & I didn't change any settings.
Thanks in advance.
I've been using AutoCAD 2008 for awhile and seem to have "lost" a setting somehow. Don't remember changing anything but I used to be able to select several items one at at time just by clicking the left mouse button.
Now if I want to select more than one item I have to press and hold the Shift...
How do you get rows in Excel to automatically resize themselves to display all of the text?
Even if I select a row and then pick Format/Row/Autofit it does not always work. "Always" is the key word. Sometimes it works, sometimes not.
Problem seems to exist even with a brand new file.
I'm...
Why do many motor circuits have circuit breakers in series with fuses? I'm referring to the main 480VAC fuses & CB ahead of the starter or drive.
I understand the different characteristics of fuses and CB's but it seems like having them in the same circuit would cause more problems than it...
I have trouble proof-reading a document when it is displayed on a computer monitor. It seems that no matter how hard I look it over on the screen I will find errors when I print it out.
Need to know if this problem is just with me or if others experience the same thing? Is it an age thing...
What is the constant used to convert inH2O to SCFM?
I have a 4-20mA Diff Pressure transmitter calibrated to 0-100inH2O going into a PLC (scaled 0-4095). The PLC needs to convert it to SCFM.
I'm told the formula is Constant*(Square root of the Diff Press)
But what is the constant? Is this...
How can I change Excel files that are all CAPITAL letter to all lowercase letters. Most of these are then put into tables in MS-Word. Word has the option of changing everything to upper case, but not the other way.
I use EXCEL to keep track of punchlist items or certain tasks.
How can I get EXCEL to automatically generate in an ID# or item number in a column "A" and keep it with the task in column "B"(without changing if items are added or deleted, etc.)
Any ideas on why the "HATCH" command will not work on my computer?
I'm using AutoCAD-LT2005 and when I click on the "HATCH" icon an error message appears saying it cannot find the file "aclt.pat". I've searched my hard drive and that file is not on it.
I selected the "FULL INSTALL" option...
Can someone explain what's happening here?
I'm using AutoCAD LT-2005 and am moving drawings from one companies title block to another companies.
When I copy a drawing to the new title block the line type layers on the drawing being copied do not show up correctly. Specifically what is...
We are going after a project where instead of a bid opening the customer is going to have a reverse auction. Is this exactly what the name implies....you start at a certain price and then the contractors keep lowering their bids until everyone else gives up? What else should be expected...
