wires in cardboard box

In a attempt to find a solution to the multiple cables running wild in my room, I thought of hiding them into a box, but I am concerned about a possible fire hazard.

The power strip has five sockets, with the following use cases:

  1. Most of the time: just the wifi router
  2. Around two consecutive hours a day: wifi router, PC and screen
  3. Sometimes or at night: wifi router and phone charger.

The dimensions of the box (as shown on the picture above) are 50×30×20 cm. If that is of any relevance, I live in France.

Is there a chance this could catch fire if I stick to these use cases? Can I also safely close the lid, which is cardboard too?

  • @HazardousGlitch mostly aesthetic, but I will settle for this kind of solution if the box is a risk.

  • why don't you attach the power bar to the wall and then bundle up the cables?

  • @jsotola I could be wrong but that sounds like a more involved and less flexible option that HazardousGlitch's one.

  • @Alexis, it is a lot easier to manage cables if the power bar is not on the floor .... it could be attached to a desk also using some nylon cable ties ...... the other benefit is that power adapters and power cords are easier to plug and unplug

Its not particularly risky, but its not a fantastic idea either.

The amounts of current you are talking about pulling is not great, so heat dissipation should nor be an issue.

No one will give you a guarantee that it wont catch fire, but it us highly unlikely provided none of the cables have exposed wiring (which might short and spark).

Why not use a plastic container instead? (Assuming a cable management solution as @HazardousGlitch mentioned does not do it for you.)


If you're worried about the fire hazard you can line it with some cheap material like ceramic tile or clay.

  • Ignition temperature of cardboard 260 C.
  • Ignition temperature of wood 365 C.
  • Ignition temperature of clay/ceramics 1000+ C.
