Wire / Circuit issues

[Anonymous]

Hi Everyone,

I am having problems when circuiting a set of luminaires which although some are emergency are all fed from the same circuit. My luminaire family has only 1 x 230v connector and one data connector for connection to TCP/IP monitoring of emergency . I have circuited the fittings so they are all from the same DB and circuit. However when I try to tag them the tag shows 3 circuits as if it was a 3 phase luminaire?

When I investigate the fittings are on the same circuit, and only have a single phase power connection. For some reason the wire serving the circuit keeps changing from 6242B B (2) 2 conductors (1 Hot, 1 Neutral plus CPC) to some strange 6242B B (2) with 2 Hot conductors, 56 Neutral conductors and 2 Ground?

How can it be possible to specify a 6242B B (2) cable where the material specified states "copper table 4D2A Ref Method B two core cable with or without CPC" with 2 Hot conductors, 56 Neutral and 2 Ground? Such a cable does not exist so why is it possible?

It sounds like you're circuiting your line voltage circuit to the low voltage TCP/IP connector.

My recommendation would be to delete that data connector and not bother modeling that system - as far as I know they don't provide any real value anyway.

You might also want to edit your family and make sure that your voltage/phase/number of poles/load classification parameters are mapped to the connector properties.

Thank you very much for your response.

Although it highlights another weakness in Revit at least its a simple answer.

Have you tried giving your connectors names so that it connects to the correct one?

Revit will probably not work correctly with wires for a 230v system in one view and a different set of wires in another view for the 24v DALI system although I haven't tried to model this setup.

Even on a bus wired system there is no facility to include a DALI A/B pair of conductors as the only choices are hot/neutral/ground.
