A few questions..........

[heatsinker]

I've tried searching for this to no avail, Maybe one of you guys can assist.

-I have recently begun to finish off the interior of my new garage. I am installing kraft-faced R-13 insulation in the walls, What is the opinion of also installing a plastic barrier over the kraft barrier? Does that pose a problem having two barriers back-to-back........Would that be an invitation for moiture to be trapped between them?

-I have a ridge vent at the peak but my siders didn't use "vented soffits", Is this a problem?

-I also have an electrical question concerning running accessory cables from the house to the detatched garage......I am running a seperate source from the pole to the garage but ran a 1-1/4" PVC conduit between the structures to run my CATV, Cat5, Phone, Alarm, etc...and wondered if that changes the requirements for the neutral/ground busses in the panal?


Thanks in advance,

Keith

A ridge vent should be used in conjuction with some type of soffit venting to allow air to enter the eaves then leave the ridge vent, thus keeping the air circulating.
Plastic over Kraft backing would definitely promote moisture and mold. I tore out some walls in an older house where someone had done that exact same thing and in between the sheets was black and slimy with mold and mildew.

The reason they didn't put in vented soffits is because they didn't put in an insulated celing. If you plan to do that, then you need to get vented soffits. Just like on a house. If you plan to insulate the wall and roof rafters instead of a ceiling then you don't need the vented soffits because you get the circulation from the room anyway.
There is no need for the plastic. Garages don't have the moisture problems houses do because they are not sealed up as tightly and tend to have a real big door opened a lot. They air out pretty well.
As far as the stuff in the pipe is concerned, don't worry about it. All the wires you are pulling are low voltage, signal carrying, wires. The computer, TV's, etc. you hook up to them all have their power and signal isloated from each other inside themselves. They will need a ground, but ground is ground, weather it from the home or garage drop.

Thanks guys....I have been obsessed with trying to figure these questions out.

Do not know much on this but I hear now you need a SEPERATE GROUND for garage, shed, etc that has electrical. I believe it may be code in MA now. I heard of someones lights going out on their shed due to lightning, then it happened to me when lighning hit outside, my shed lights went out. So now I have a ground in every building.

Is this separate ground supposed to keep the lights from going out during a lightning storm?????

If he has a seprate drop from the pole for the shop, then he has a seprate meter for the shop, and a ground soil spike should be part of the meter install.
It sounds to me like the only connection between the house and shop is the TV, computer, etc. And that is only signal, no power.

Sorry if I was a little vague in my post.

I am having a seperate 150amp service panal feeding the garage from the pole. I will have two meters, one for the house and one for the garage.
My concerns were because I plan on running wires through a buried 1 1/4" PVC conduit that I put in during constuction. I planned on running a computer cable (Cat5) to connect to my home network and for internet access in the garage, Also a Coax cable for cable TV and a bunch of alarm system wires (sheathed) to enable the garage to be added on to my existing alarm system as a seperate zone. I want to be able to arm/disarm the alarm independant of the house.
I was reading up on any problems I might encounter and kept seeing statements refering to not having two seperate electrical services tied together (granted the examples were more like a water pipe) and started thinking about those wires I mentioned earlier. It said something about seperating the ground from the neutral busses. I see only three wires at the mast for the garage and I know the electritian drove 2-8' grounding rods next to the garage.

I hope this clears up my question, and any comments are greatly appreciated. Am I still in the clear?
