How to use existing channels when replacing wiring in a panel building
Do you live in an apartment in a panel building? Are you renovating or planning to do so? Thinking about replacing the wiring? This video shows how to use existing ducts.
Using existing ducts when replacing wiring is recommended when:
the apartment will not have suspended or stretch ceilings;
wiring needs to be hidden in structures that cannot be cut (beams, floor slabs, etc.).
When replacing electrical wiring through existing ducts in a panel building, it is important to:
know how the wiring is routed inside the rooms and on the stairwell;
determine whether the ducts are pass-through or not. That is, whether it will be possible to pull the cables into the duct.
