Hello to all home builders and possibly also to electrical experts,
Since I haven’t found anything about this online or in forums, I’m posting the question here again.
We have contracted the interior work through the general contractor, which unfortunately includes the electrical planning. Of course, the standard package does not include any LAN cabling, which the electrician charges extra for. Is a price of 300 gross for positioning the CAT7 cable and pulling it through a house with a floor area of 130 sqm (1400 sq ft) reasonable or too expensive? (Only one LAN cable; the price doubles for two.) Terminating the data cables and installing the network outlets is charged separately.
We are getting a prefab house (timber frame) with a ground floor and an upper floor (attic). The plan is to have the phone hub in the utility room, installing a router and a switch there, and from there to connect the rooms with double outlets and double CAT7 cables.
The electrician charges quite a high price for this and, what confused me greatly, wants to run the LAN cables inside conduit (empty pipes), supposedly for protection. However, despite the conduit, you would not be able to replace the cables later! Does this make sense? Is there a relevant DIN standard or is it common practice not to lay the cables openly? Who has experience with this or has already done it this way? So far, we have only arranged for the pulling in of the cables with termination on the outlets. The rest of the work in the utility room has not been included yet!
Would it possibly be feasible for a layperson to do this work themselves? The ceilings are still open, the cables will be laid along the rafters, and horizontally there are installation cables or the walls are not insulated everywhere, so cables can be pulled there.
Thanks in advance for professional feedback.
Best regards,
Charly

cobra19825 May 2017 06:35If you want two LAN connections, do you need to run two Cat 7 cables? Just asking out of curiosity.
Yes, exactly.
For me, one LAN connection costs €68.75 (approximately $68.75). I have about 16 of them.
In addition, 2 patch panels with 8 ports each: €104.38 (approximately $104.38).
Then a flat rate for installation: €280 (approximately $280).
That includes everything.
With tax and discount, I end up at €1,678 (approximately $1,678) for the whole house.
So your €300 (approximately $300) sounds very cheap.

A LAN cable contains 8 wires, so you could connect 2 ports. However, this is usually done only in existing installations and when there is no other option, but not in new builds. Doing so limits the functionality of the ports—for example, Power over Ethernet (PoE) is not possible, and instead of 1000 Mbps, you will only get 100 Mbps throughput.

cobra19825 May 2017 08:35Cat7 cables have 8 cores. To use them fully, if there is only one outlet, it is better to use one cable per outlet; with two outlets, using two cables is correct, right?

Knallkörper5 May 2017 08:39This is a duplex cable, essentially two cables in one, each with 8 conductors. This way, you don’t actually need to pull two separate cables.
