Hi guys I would just like to seek some clarification on running multiple circuits in conduit.
This is for a domestic installation, installing 2 new circuits, one of which is 6a lighting circuit and the other a 32 a ring main. Both circuits will be run in round pvc conduit which will be surface mounted.
Am i right that due to it being a domestic installation, and both circuits not running constantly at full capacity then there is no need to derate the cables, and that spacing factors are not really required? essentially as long the cables/conductors can all fit inside the conduit then there is no problems?
With regards to running the conduit i have a couple of questions about best working practices.
1. Do you suggest running both circuits in the same conduit system and then dropping down to the relevant sockets or light switches?
2. Is it better practice to run each circuit in there own independent conduit system?
3. What size conduit would i need to run a ring main and lighting circuit in the same conduit? will 20mm or 25mm do the job?
4. Is it ok to run T&E in conduit?
