I need to supply four 110v/15amp circuits temporarily for a temporary function to the backyard. So I could add four 15 or 20 amp breakers to my panel and run four wires from the panel to the backyard.
But, could I save on wire and just run one or two of those fat wire that supports 220v/40amp circuits instead? I have some of that wire lying around. How would I get two (maybe four?) 110 volts at the other end?
