A lot of variables in this. First you have to determine you load. In this case 30 amps. I do know that 10 gauge will deliver 30 amps for a run of 200 feet. I can't cite charts on here, I just know this from practical application. (My pool pump was installed with these specs) Now 50 amps at 200 feet would require bigger wire. Also 30 amps at 500 feet would likely require bigger wire. Its all in how much voltage loss occurs in the wire. This loss is also determined in type of wire, copper, aluminum, gold, etc. As well as the ambient temperature of the area. I hot factory would require shorter runs when compared to wire underground. I only have a phone app now but you can Google amp capacity charts and you should find a chart with your application. Being residential use the following in your search as it's the most common stuff used. copper wire , 10gauge, 30 amp load should give a max length.
