John Russell asks about whether an armoured cable be laid in a PVC conduit. His question is answered by BASEC (Theme - Cables, Wiring & Wiring Accessories):
Question: Can an armoured cable be laid in a PVC conduit for aesthetic purposes?
Answer: PVC sheathed armoured cable could be placed in PVC conduit. A PVC sheathed armoured cable - such as BS 5467 - could be enclosed in a PVC conduit with few ill-effects.
However, if the cable is a low smoke halogen free type (e.g., BS 6724), or has specific fire performance (e.g., BS 7846), then the use of a PVC conduit could have deleterious effects on the cable in a fire, and guidance should be sought from the cable manufacturer concerned.
Other types of conduit may be more suitable.
