Hi.
Been asked to run a remote router with wifi to an attic. Would like to use cat5, 2 pairs for network and the remaining 2 pairs to power the router remotely. 12 volt dc. Wanting to do this because running separate power may be difficult. Very old house, existing wiring is extremely fragile.
Wanting to know an very approx expected maximum amperage that can be pulled through a strand of cat5 over say, 1m 10m and 50m lengths. What kind of volt drop can I expect for those loads?
Or should I just run a beefy figure 8 up there?
