Calculations & Checks / Conduit Sizing

« Last post by mbd-uk on 10 December 2023, 18:08 »

Can anyone assist with understanding and resolving the 63mm conduit for 2 x 2.5mm Twin and Earth?
While the cable length in 80m only final drops will be installed in conduit.

ElectricalOM for Advanced Users / Surge Protection Kit

Where the supplier provides surge protection as a kit, is it possible to install the SPD as a direct connection, without using a way number.
This application is a single phsase consumer unit

ElectricalOM for Advanced Users / Re: RCD Protection

Hi AndyZ,

If that box is not checked EOM will consider the overcurrent protection device as the main device for the earth fault calculations and checks. If it is checked, the RCD data will be used for earth fault calculations instead. This is only relevant to TN systems.

Hope that helps.

ElectricalOM for Advanced Users / RCD Protection

Hi, recently, during my design, I noticed when selecting protection devices, there is a tick box for the 'additional RCD/Earth fault protection'; and another tick box for 'RCD Devices are only used for additional protection'. I wonder in what condition those box should be ticked? Thanks.

Calculations & Checks / Re: Parallel conductor It(A) critical message

Spacing the cables, if possible, can help as the grouping factor will not be considered

Calculations & Checks / Re: Parallel conductor It(A) critical message

EOM calculates and displays the result for one conductor of a parallel bunch, so, what you see is the current would pass through via one conductor of the whole bunch. To remove this you need to reconsider your cross-sections.

Calculations & Checks / Parallel conductor It(A) critical message

« Last post by mattwilson83 on 08 November 2023, 09:44 »

I always get a critical message when using parallel conductors, the It(A) is only calculating the single conductor and not the parallel conductor. Is there a way to clear the critical warning.

Hello,

We made some changes and the Excel-based report will work as expected with extension boards. This will be available in the upcoming update. Please see the image below:

Hi Mert

Thanks for the reply. I think the excel templates will be very useful.

I've just been trying out the ones already in ElecOM and I have a number of boards with an 'extension board' but they are not recognised as split boards for the excel templates. They are recognised as a DB but don't display the extension board part. Am I doing something wrong?
