I have 50 feet of 10/3 SJTW wire. I'm thinking of making a 30 to 40 foot extension cord and possibly using some of the wire to connect an inverter to the house batteries. The inverter will be no more than 1,000 watts. We only have two 12V batteries and will only use the inverter to power a computer and the television. Depending on where I put the inverter, it will take maybe 10 - 15 feet of wire. Is the 10/3 wire adequate for an inverter or should I go with heavier wire.
