(it would probably then be labeled as a 12000) AND it has a 50A breaker on the gen, then you might as well go ahead and do a full 50A setup. In the unlikely event that your "9500"w gen is really 9500w contin. But #10 is easier to work with and cheaper and you gain little or nothing from 50A setup with a 7500 running watt gen so you probably have no good reason to not use a 30A setup. Now if your run to the inlet box is only a few feet and your gen has a 50A outlet, it's not gonna hurt to do the setup as 50A/#8. This combination is not unsafe (30A is the safe capacity of the wire and if you try to push more thru for more than a few minutes the breaker will pop and protect you) and you are not really leaving any generator capacity "on the table". So a 30A breaker and a #10 wire will work just fine for you. And that' fine - very few houses actually draw more than 6000w continuous. Probably (I'm guessing) your "9500" generator puts out 7500 rated watts (31A) and really you don't want to truly run it continuously for more than 6,000w (25A) if you want it to have a long life. You can ignore surge - not only does your generator have surge capacity but so does your breakers, your wiring, everything. First of all, the "9500" watt generator is probably not really 9500 running watts. The breaker will be sized for either the supply or the load. It appears that the 15A and 20A circuit breakers for this panel only. The panel where the circuit will originate is a Siemens G2040. Due to length, 4 AWG is called for to hold voltage drop within 3. I need to run a long circuit out to a stock tank heater in a pasture. The breaker plus distance plus whatever code exceptions may apply will tell you what wire needs to be run. 4 awg wire too large for circuit breakers. Lastly the wire doesn't dictate breaker size. Makes sense if your gonna upsize your gen someday otherwise it's a waste of money on the bigger breaker and larger wire size required. I'm not sure why folks are telling you to put a 50 in. Much more than that I would upsize to #8. If your going to be 100ft or less from gen to panel you'll be good with #10 wire. You need to be in the 12000w running amps range to get a true 50A output.Įdit: because it seems everyone wants you to spend money you don't have to. Even most gens with 50A outlets are protected by 34,39, etc. Typically a gen won't output it's total capacity via the main "big" plug. If the output breaker on your gen is 30A then all you need in your panel is 30A.
