Chuck, I would not advocate using one side of the 240 volt feed and neutral for a 120 volt feed. If the need is to run 240 volts to the shack as well as 120 volts, pull two lines, and put a breaker on each of them. Yes, your "solution" will work with a 3 wire with ground wiring run, but if split out to two 120 volt sources, the current on the neutral may exceed expectations for the wire size used.
A 240 volt AC run can be made with 2 conductors and safety ground. A 120 volt AC run can be made using 2 conductors and safety ground. If you want 240 volts, start with a 240 volt run from the service panel, if you want 120 volt service, start with a 120 volt run from the service panel. Do not mix the two (even though it "works"). Your safety is at stake - stick to the NEC requirements and guidelines. 73, Don W3FPR On 2/15/2011 7:25 PM, K4SC wrote: > If I were going to the trouble to pull the wire, I'd run 220V.
