A doorbell is only 2 wires -- if you pull Cat5 for future proofing, could you bind 2 or 4 of the 8 available wires to safely pull the current? Obviously, the other end can't be plugged into a network switch till it's properly wired up. I don't have enough electrical know-how to figure out if this works... Edit: Based on a table I found; 24 gauge wire has a resistance of about 25 ohms per foot, where as 16 gauge has a resistance of 4 ohms per foot. So; assuming each wire is a parallel resistor, 2 pairs(4 wires) would be about 6.25 ohms -- so it could heat up a bit more than proper wires. so .... maybe as long as someone doesn't hold the button down for too long? |
