We have concrete wideslab flooring to both ground and first floors and as a result have installed maxi trunking beneath the first floor to accommodate all electrical wiring (single cables not twin & earth); all cables were placed in conduit, chased into the walls prior to to plastering.

We have several outlets identified for cat 5 cable - is it possible to place the cat 5 cable in the maxi trunking along with the electrical cables - probably not - if no, would placing the cat 5 cable within another conduit before placing in the trunking be an option? If no again, would placing the cat 5 cable in a conduit and then fixing above the maxi trunking be the solution? This would keep electrical cables and the cat 5 cable about 100mm apart.

Any recommendations/suggestions would be gratefully received.

Thanks folks.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16501&Focus=279584#Comment_279584 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16501&Focus=279584#Comment_279584 Fri, 20 Mar 2020 23:15:40 +0000 Peter_in_Hungary http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16501&Focus=279588#Comment_279588 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16501&Focus=279588#Comment_279588 Sat, 21 Mar 2020 10:58:38 +0000 goodevans
My gut says the 50Hz AC power is too low a frequency to have an effect on the data signals. however spikes and other noise in the power cable may have an effect (again I think low risk). If there were a problem I would look at locating noisy frequently switching items such as USB chargers, florescent & led lighting, anything that says 'inverter technology' All these items should smooth the power draw - but under fault conditions MAY cause problems.

I predict you will have no problems - keep it simple, use regular UTP cabling and all will be well (asaik to get the benefit of shielded cables careful attention needs to be taken to earth the shielding - I think at one end only - but it is complicated I think.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16501&Focus=279594#Comment_279594 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16501&Focus=279594#Comment_279594 Sat, 21 Mar 2020 15:24:09 +0000 MatBlack http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16501&Focus=279600#Comment_279600 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16501&Focus=279600#Comment_279600 Sat, 21 Mar 2020 16:50:10 +0000 djh Posted By: MatBlackFor the relatively little extra, its worth using cat 6 instead for a bit of future proofing. Its a bit less flexible cable though, steady on the bends.
For myself, I took the opposite decision, that the extra complexity of meeting the cat6 bending and connection rules wasn't worth it given my likely usage. I can't see me needing more than a gigabit to any device, and switched fabric means connections don't need to be shared.

It's perhaps worth pointing out that there are flexible cables, which use stranded wire, and less flexible ones, which use solid core. The solid core is intended for permanent installation and the stranded is for patch cables that undergo repeated flexing.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16501&Focus=279623#Comment_279623 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16501&Focus=279623#Comment_279623 Sun, 22 Mar 2020 19:46:31 +0000 XT600 ]]>
