Honeywell 14/4 Connecting Cable (per foot)

This stuff says on the jacket that it is rated for sun exposure.

I highly recommend this cable as it's not only sun rated, but it's also rated for outdoor use meaning that it's waterproof compared to water resistant. I recommend that you always buy 10' more cable than you think you need. The price offered by eComfort.com is very competitive.

If you order the kit they short you on the wire. I ordered the kit with two 25' line sets, wire, tubing, and some misc stuff. Well if you use the full lengths of your line sets like I did then you need a couple of feet extra of wire on both ends. So you tape wire and line sets together and leave 2' extra on each end and you can only do one line set with the wire provided and the remainder is too short for the other line set. So a trip to Home Depot is in order to buy 30' of 14/4 about 35 bucks.

Check your installation manual, and local codes. But for most smaller units, ie 6k, 9k, 12k indoor units, this cable is more than you will need.

It is fine to oversize your control cable on a single zone installation, but if you have multiple zones, the wire gauge becomes an issue.

Otherwise, this is a top of the line cable. great to work with, easy to strip and crimp, and more than fits national code in mini split application.
