ᐅ Cutting channels (positioning during ceiling installation)

Created on: 10 Jun 2020 13:10

Hello, I want to make the channels for the electrical installation myself. I am familiar with the installation zones. Normally, horizontal channels are made near the ceiling, with a minimum distance of 15 cm (6 inches) below the ceiling.

In my case, there are empty pipes installed in the ceiling at close intervals, all leading to the same outlet strip.

Should I first run each empty pipe down by 15 cm (6 inches) and then combine them all into one common horizontal channel running to the left, and then run that channel vertically downwards?

Or, in such a case, can I directly make a horizontal channel about 3-4 cm (1-2 inches) below where the pipes come out, and then run it to the left and down?

What is the best practical approach to this?

Thanks and best regards!

What do you still want to use satellite for today? In any case, satellite and LAN cables should not share the same empty conduit with mains power cables. Trying to pull cables through the tiny protective conduit afterward is practically impossible.

I’m currently wondering about something everyone faces with this topic: running LAN and SAT cables through conduit or directly under plaster. For the first option, I would need to extend all the relevant conduits anyway.

There are M25 connectors for your conduits. They cost around €1. Still, I don’t understand why it’s done so short. It was known what needed to go there. So why not just leave them longer from the start? I mean, they cost about 50 cents per meter. Even with some leftover length, it won’t break the budget.

I actually have to disagree with you here. I assume we’re talking about M25 conduits. That works perfectly fine. Even duplex cables can be installed without much trouble. The main issue is just getting the wire through the conduit. The actual pulling process is less problematic.

I’m just going to mention “bending radii” and “resistance to deformation”—we recently dealt with this regarding a thick drainage pipe hose between the house and the garage. My skepticism about combining protective conduits with blind trust has its reasons.

There are push-fit couplings available for all common conduit pipes. These simply snap on to extend the conduit pipe.
