and just to add to your comment, although not all of it...but some of the walls along which the wire will run are facing the east..so sunlight maybe a problem! <br><br> <div class="gmail_quote">2009/10/20 javadayaz <span dir="ltr"><<a href="mailto:javadayaz@gmail.com">javadayaz@gmail.com</a>></span><br> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">exterior grade means a pipe bascially through which the wire will run?<br><br> <div class="gmail_quote">2009/10/20 Philip Stubbs <span dir="ltr"><<a href="mailto:philip@stuphi.co.uk" target="_blank">philip@stuphi.co.uk</a>></span> <div> <div></div> <div class="h5"><br> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> <div>2009/10/20 javadayaz <<a href="mailto:javadayaz@gmail.com" target="_blank">javadayaz@gmail.com</a>>:<br></div> <div>> just the general elements...water and snow primarily!!!<br><br></div>The cable will be fine in snow and water as long as the outer sheath<br>remains intact. After installation, the biggest threat is likely to be<br> UV. This will break down the polymer chains in the sheath causing it<br>to become brittle and crack. If you are on a north wall, it will<br>probably last for years. On a south wall, one good summer could do<br>significant damage.<br> <br>It is hard to say what would be sufficient for you without seeing<br>exactly where and how the cable is to be fitted. If changing the cable<br>in the future is not going to be easy, then invest in exterior grade<br>now and be done with it :-)<br> <br>--<br>Philip Stubbs<br><font color="#888888"><br>--<br></font> <div> <div></div> <div><a href="mailto:ubuntu-uk@lists.ubuntu.com" target="_blank">ubuntu-uk@lists.ubuntu.com</a><br><a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk</a><br> <a href="https://wiki.ubuntu.com/UKTeam/" target="_blank">https://wiki.ubuntu.com/UKTeam/</a><br></div></div></blockquote></div></div></div><font color="#888888"><br><br clear="all"> <div></div><br>-- <br>Regards<br><br>Javad<br></font></blockquote></div><br><br clear="all"> <div></div><br>-- <br>Regards<br><br>Javad<br>
