When generating distribution schedules with MICC cabling, utilising the sheath.

The DB schedule does not detail the sheath as being used as the CPC.

Can this be amended to detail that the sheath is being utilised.

Hello,

The current release has an option for an additional core for lighting circuits that only cover the emergency lighting case. We modified this and in the new beta version, we will cover any case with the option "EC" - Extra core/conductor as shown below:

Is there an option to advise the installer that a Three Core and Earth wil be required for Domestic Fire Alarm Circuit and I can only see Twin and Earth.

This is also an option for cabling between certain luminainre with integral controls.

Hi,

You can try to select the board you want the SPD protect, and navigate to Protective Devices tab of the Circuit Editor. You will see subordinate tabs one of them is Surge protection. You can tick the Use SPD at Incomer box and this will insert an SPD at the incomer side of the selected board.

Calculations & Checks / Re: Conduit Sizing

« Last post by Mert on 11 December 2023, 05:18 »

Hi,

We cannot see all the settings from this screenshot unfortunately. However, with this cable type, circuit type and installation method EOM suggests a conduit size of 16. I tested this, by the way. I would re-check the settings and parameters, and re-check the conduit size dropdown list. If these do not work please contact support.

Regards.

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.

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.

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.
