Re: Current carrying capacity of CAT5?

[ian.bird@xxxxxxxxxxxxxxxxxxxxxxx]

I have a memory from a while back when this came up and it was about 300ma
per pair (one plus, the other minus) depending on distance. I use CAT5 for
my watering valves which draw 230ma at 12v and I have set it up so only one
can come on at any time. Keith Doxey was the guru answering the questions
then.

500 mA should be fine.
