Cable and telephone in the same conduit?

[Motown 454]

Hi I'm getting ready to run the conduit for my electric, cable and Phone. The run is about 35 ft long from the main panel in the garage to the panel in the house. I'm going to put in 2" conduit for the power from the garage to the house which is going to be 100 amp. it will run under the garage floor. Do I need two seperate conduits for the phone and cable or just one?? What size cable for the 100 amp power? I've looked at past posts and I know you can't run aluminum inside the building so I guess I will need to run copper. Any help is appreciated.
Thanks Wayne

All low-voltage cables can be run in one conduit. Phone, Ethernet, Cable, etc. are all low voltage, you can run as many as you can fit into that conduit.

Just as long as the high voltage line is in a seperate conduit & the two conduits are spaced as far apart as possible to avoid electrical field interference. Minimum of 6" apart.

I ran 95' of 2" conduit from my home power to the detached garage. I used ONLY 90 degree sweeps and that's a must. The wire pull for the power (4 wires) was a breeze and went without a hitch.

Run just one 1 1/2" conduit for the data/phone cables. There's more than enough room. Also, don't forget that when you pull your wires through, also pull a 2nd pull-rope in as well. Someday, you may be glad you did.

you can run aluminum in the building (unless you have a local code that prohibits it) you just cant run URD type cables, has to be a NEC wire type such as THHN, RHW, XHHW

Just a FYI, 480 volts is considered LOW voltage, it would be better to refer to the feeds as low voltage & line voltage, since "high voltage" is mostly the realm of power company linemen...

My Dad's place has all that run in 1 conduit. One building we did in 1990 and the other in 2008. No cable though, don't even that have in the house!

FYI....Ethernet Cat5 or Cat6 makes very good phone cable....and is typically cheaper than phone specific cable.

Guys when do you need to step up to schedule 80 pipe ? I know you can't speak for my area but will I get introuble if I run the conduit without a permit? or is that ok if I have an electrician run the wire later?
John which is better to use Cat5 or cat6 ? Right now all I have is the cable bundle of TV Phone and internet ,but I want to run a wire for the telephone in case I go back to Verizon in the future.

Schedule 40 was ok in my area. Some areas require schedule 80 where the conduit comes out of the ground. Yes, it should be inspected. If you don't inspect it, they can make you expose it before they will sign off the installation.

Here is mine .... one for the low voltage stuff and the other for 240 volt shop power....

X2 on running the low voltage in a separate conduit. Cable should never be run parrallel to electrical wire to reduce interference. Based on research they even suggest to cross them at 90 degrees if the must intersect. I have seen it done several ways, but if you are already making a long run, you want the least amount of interference.

I ran a 50' run of cable/phone/CAT-5 to my garage from my house. I have a separate meter for the garage so I ran the wires in on the opposite side. Because of the 50' run, I used RG-11 cable for the main run through the conduit. It is a lot larger and carries more current. Cost a little more (especially with connectors and crimping tools) but I do not want to ever have problems underground.

I would use the CAT 5 or CAT 6, CAT 5 is cheaper and will be fine for your application. 5 or 6 is good to 300’. They come in 1000’ rolls (box) so pull a spare.

for telephone there is no distance limitation. The 300ft (100 meter actually) only applies when the wire is used for ethernet

Holy **** dude, I don't think I have ever seen a trench right that straight/square before!

The inspector said the same thing?

I hand dug it..... about 50 feet. Took about a day. I thought about renting a mini excavator but thought buy the time I got it delivered and then back it would be all day anyway...... not to mention that the work out and few extra bills in my pocket couldn't hurt.....

The big assed rock on the left side of the ditch was kind of a *****......

Wherever u read this, its incorrect! Aluminum is commonly used as feeders to subpanels and large branch circuits!

Yes i saw that but had to correct a misnomer i saw in the OP!

I don't care if this is an old thread ! Where do you find Cat6 cable less than phone wire (Cat3) ?

 

[wyliesdiesels]

Good point! I missed that one!

At my work for free.............just kidding....

When you buy the 1000' roll to use for Ethernet.....chances are your going to have some left over....cheaper than going down to buy just phone specific wire.

When you compare the cost/ft....a small roll of phone is more than the cost/ft off that 1000' box of cat 6

You're not going to take the opportunity to suggest he buy a Honda Civic CNG?

He is waiting to find out what country he lives in.......

Came here for the pictures of the super-straight trench, was disappoint.
