We just use the inexpensive 18/2 sprinkler wire found just about anywhere for runs up to 2000' -- over that, go with the shielded.
Another way to go about super long runs might be to use a radio transmitted float switch. Have yet to try it, but they look nice and as I recall only a couple hundred bucks or so. http://remotecontroltech.com/Applications/pumpcontrol.aspx Best regards, Mark Dickson, NABCEP Certified Solar PV Installer T Oasis Montana Inc. _____ From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Bob-O Schultze Sent: Monday, August 23, 2010 6:45 PM To: RE-wrenches Subject: Re: [RE-wrenches] Grundfos SQ Flex Float Switch Hiya Kirpal, They are just signal wires from the CU200.

The float switch has 3 #14AWG wires.......I need to add about 700 feet of wire from the CU 200 controller to the storage tank.....I want to use #18AWG......is this okay? most float switches I have used do not carry current they are simply signal wires and can use very small gauge for long distance..... Anyone know off the top of their head?
