Calculations & Checks / Re: Calculating SWA cpc using the armour and separate conductor
« Last post by admin on November 26, 2021, 11:03:00 AM »
Further to the above, we will include the option to consider the magnetic effect of the SWA when a separate CPC is involved based on the PD CLC/TR 50480:2011 UK NA.

Also, we will include the other checks about the separate cpc withstand and also the SWA cpc withstand, based on the portion of the Ief in each case as mentioned in the UK NA.

I hope that helps and many thanks again for the feedback.

Hello,

The GN6 notes have been considered for the SWA resistance calculation.

The PD CLC/TR 50480:2011 NA correction has not been considered though. This is something we will look at and most probably include as an option.

Thank you for the feedback!

Hi

I can you tell me if the software uses the calculations layed out in GN6 amd GN8 that adopts PD CLC/TR 50480:2011 which adopts annexe NA (for the Uk) methods of working out the  size of cpc for a 90 degree SWA thermosetting cable in excess of 100A per phase. Separate cpc and armouring alone. 

Within it contains calculations that the UK now uses (since 2015) to determine the magnetic effect the armour has upon a a separate parallel cpc run with the armour for a thermosetting  SWA cable taking into account the DC resistance of armour

It was adopted into BS7671 2008 (2015) Amd 3. You might remember it being the document that changed the Maximum earth fault loop impedances given in Tables 41.2, 41.3, 41.4 and 41.6. Back then.
GN6 references it (Page  81-83) along with GN8 (page 140) And app 4 BS7671 2018 SECTION 2.5

Thank you

Hi,

When coping in cad you can move your mouse to point to a direction and then type a distance that will denote the length to copy the figure. The action submits by pressing enter and ends with mouse right-click or by pressing escape.

Similarly, when drawing a line you can set the start point and then move the mouse right, for example, and type the length you want the endpoint to be located from the starting point.  Again the action submits by pressing enter and ends with mouse right-click or by pressing escape.

You can always review the action progress at the command area.

Also, the ortho mode helps be on a straight line.

See the video here that will help:  https://nextcloud.com.gr/modecsoft/index.php/s/Frd79fZPGywqgs9

Hi I have never used normal CAD. Where do I type the required distance? Equally when I draw a line how do I know the distance of that line?

its like normal cad. copy the symbol move the mouse to the direction, type the distance in metres and press enter. Or draw a line as a guide and the osnap to the end of the line

Hello,

Is there a way of measuring a known distance? So say if I wanted to place two lights 1.2 m apart on an already scaled drawing, how would I do that, I know I can measure using the measuring tool between two fixed points but not sure about the former. 

Thank you

CAD Plan Design / Re: Wiring - High Level/Low Level Wiring

From the properties on the right hand side, you can edit the elevation of each cable section, if you are working on the same floor/electrical layer.

If you have multiple floor layers, again from the properties on the right hand side you can add extra cable length, see the image attached.

CAD Plan Design / Wiring - High Level/Low Level Wiring
« Last post by mbd-uk on October 21, 2021, 02:39:38 PM »
I have an installation where the Submain Cable running between 2 DB's, installed at high level and then drops to underground.

Any advice on how to enter these 2 installation levels in CAD plan as a single cable?

Thanks
