Renkara Offices - Electrical

Electricians came out and put in the wiring for data and electricity. The electricians ran two conduits from the house to my office. One conduit is for the electric and one conduit is for the ethernet cabling. Need separate conduits because it is not a good idea to run high voltage together with low voltage. The high voltage conduit includes a 220-volt line for the new air conditioners.

With all of the electrical connections, we decided to put a dedicated fuse box on the back of my office.

For data we are using shielded Cat 6 ethernet cable. I was tempted to go with Cat 6a but that stuff is just too thick and requires a much larger bend radius. Note: if you ever do want to run Cat 6a cabling, be sure to specify that before the conduit is buried - the electricians need to account for the bend radius at all corners.

We ran 5 separate Cat 6 lines from the house. Three of them are dedicated to the security system. That leaves two lines running to the router in the house. For the record, 5 Cat 6 cables is all that would fit in the low voltage conduit. It was fairly entertaining watching them pull those cables through. As mentioned, the ethernet cable is fully shielded so there should be no interference between cables in the conduit despite the dense packing.

I started with 1000' of Cat 6 cable. Not sure how much is left but probably at least a couple of hundred feet.

The two ethernet cables that aren't dedicated to the security system terminate above the windows in my office. There will be a set of floating shelves above the window which will support the office router, office wireless access point, NAS, and other network devices. Technically we only need one cable to run to the house but I wanted to have a backup.

Ethernet cables also run from this location down to a port below my window and across into Ahu's office to a port below her window.

I also ran a 1" plastic conduit - called a "smurf tube" by the electricians - from this shelf area above the window down to a port close to the floor. Why the smurf tube? I don't like to see cables and ethernet cables aren't the only cables I use. In particular, I'm probably going to buy an even bigger NAS for my own use - Promise Pegasus - and that device uses a Thunderbolt cable. With the smurf tube, I can just put that device up on the shelf with everything else - where there is also UPS power - and just run a little Thunderbolt cable through the tube down to the desk. Never have to see the device at all.

Interestingly, none of the high or low voltage cabling is required to be in conduit within the walls or ceiling itself. All electric and data cabling comes in at my office and runs across the breezeway ceiling to Ahu's office. There is no conduit other than that which was buried between the house and the offices.
