Basic AC feed

JPLefebvreJPLefebvreOGR Forum Member

I am very aware of all the DCS wiring precision Barry lists in Part III of the DCS companion to obtain the best DCS signal possible from TIUs to tracks. However, I cannot find (except for wire caliber) specifc precisions on the length of wire between transformers and TIU.

 

1-Would a 16 gauge stranded twisted pair wire be OK for 100 to 200 feet between transformers and TIUs. If not, what type of decay the AC signal would suffer and how would it affect the DCS signal at the TIU output?

 

2-Any place on this forum where this subject was discussed that I could refer to?

 

Thank you very much.

JP,

I have used this voltage drop calculator. You need to know the current or use the maximum of the transformer and the voltage. Note that the length is doubled (single set of conductors, hot & neutral).

 

Short answer, use 12AWG stranded and don't worry about it.

 

There are many threads discussing this. Mix up your search terms. But, I believe the critical portion is the number of power divisions (blocks) from the TIU to the track and your only concern is minimizing voltage drop both to and from the TIU.

 

Hopefully, others will chime in with their experience.
