The barn is about 50ft long so that would be fine if I could just get the power right. I looked for some pre made cables since I don't have the right tools to put on the connectors. I can't find any like 14 gauge wire or anything. I looked at a chart online that said for 500mA to go about 700ft I'd need 12 gauge and to go about 480, a 14 gauge. Do u know where I can find those gauges in a premise Siamese?
