Clearence Between Cable Ducts

08/02/2011 4:29 AM

Dear friends,

I want to make some cable ducts in our boilier area for the construction of the new boiler. We have one MV cable , some LV cables and some control cables. So i want to know that these cable ducts can we make near by or any distance between these cable ducts. Suppose we want to make the distances what is the clearence between these ducts as per IEEE. Expecting your valuable commands.

Thou shalt make sufficient clearances between these cable categories. Consult NEC, BS, IEC, IS, etc., according to whatever your local code is.

300mm would be ideal as per IS 1255.

300mm would be ideal as per IS 1255 (now that I've heard it twice.)

Maybe 300km would be even better?

If you are making separate ducts then all that is required is base on convenience of maintenace.In the same ducts also with sufficient clearance cables of Different voltages can be laid
