Need Help, I am not a electrician but am capable of wiring. I need help I have 2 problems one , a dog in the back ( anyone needs a lab) and he chewed up what seems to be the remote line from the house to the A/C . I have a gsc 130481 ac , the AC works but the fan outside doesn't work due to dog chewing the lines the remote line is out.
There are 2 lines One seems to be the major the heavy duty line but the 2nd is out, there are wires coming from the house Red, black, yellow, blue, white, and orange that connects to the a/c. So my question is can some one help me wire the A/C , note there is a yellow and a blue coming from the a/c from the outside , please help...

857-1450 to explain better if any one can help

Thanks

The AC typically requires only two wires and they go to a contacter. I would reccomment getting a length of tstat wire from a hardware store or an AC contractor. If you only need about 3' it might even be free.

For splicing, I'd advise soldering with heat shrink tubing on the wires. I don't trust anything else. For the outer cover of the splices I''d silicone self-fusing electrical tape 3M Scotch Sefl-Fusing Silicone Rubber Electrical Tape 70 (http://www.mpsupplies.com/3mtape70.html). Keep the colors the same.

I would arrange the wires such that a drip leg is used.

If your really having problems with "a dog" then mount a water resistant junction box on the wall and splice with a european terminal strip with a wire protector (Radio shack's version doesn't have it) or wirenuts.

Then use flexible conduit to the air-conditioner.

You can always fill the conduit with tabasco sauce. Just kidding.

Maybe you should call an electrician
It is their job, and it is much safer.
A lot of people get electrocuted doing these jobs for themselves instead of calling an electrician
Well, good luck with it either way, just stay safe :)

An outside A/C unit has 5 wires not 2. You have a pair of light duty control wires from furnace often blue and yellow, often the only 2 out of a 4-5 wire cable used at the A/C. You have 2 heavy, power feed wires plus a ground coming from a disconnect. They are hot all the time, so you want to be very careful about keeping the dog's teeth away from them. As for doing the work yourself, there is no way you will get hurt if you throw the breaker inside before touching the wire. Cutting power to the furnace will keep you from blowing its control wire fuse while working on the control wires. For them, I would run new wire from the A/C to inside. Any old thing #18 or larger will work. Inside, you can wire nut them to the old wires.

I had covered the wiring and foam insulated tubing with expanded metal, but my one puppy managed to pull it off, destroyed the foam and control wires, and chewed holes in the flex. I didn't want to take any chances with valuable dogs. I replaced the plastic disconnect box with a metal one. I ran rigid conduit from the disconnect to the A/C unit. I managed to pull out enough cable to make the old control wires reach. I put pipe insulation over the vapor tube, and then covered it and the control wires with a length of stove pipe. Ideal, it comes opened up and I wrapped it around and snapped the seam together. I had to patch some gaps with furnace tin. That was in the spring of 03, and 4 Lab puppies and many visitors later, I haven't had any problems.

Using the rigid conduit worked much better for having a neighbor I could borrow a conduit bender from. ''Dan, can I borrow a hickey?'' We have knowledgeable people here that may be able to suggest something with adequate mechanical properties and easier to work with than the rigid conduit. You can buy elbows, but then you have to cut and thread the pipe. I must confess cutting pipe thread on the one end, rather than a proper conduit thread.

If you are having other chewing problems, drop in at the dog forum.
