Generator will run, wont output electricity - Electrical Supplies

You really didn't provide much info to work with - Knowing the make & model & size (as well as its age) would be helpful. Also is it new or have you had it for a while? What test equipment do you have? In other words, what are you using to determine if it is putting out electricity? Has it ever worked? All generators have individual circuit breakers, so try resetting those. If they trip-out immediately then disconnect the generator from the load. reset the circuit breaker(s) again & recheck the output some other way, such as by connecting a table lamp to it. If that works, then consider the possibility that your generator may be too small for the load that you're trying to connect to it. For example, a 2000 watt generator is good for a working load of 1000 watts but is too small for a 2000 watt load. If this is your first experience with a generator, check out the web site www.electricgenerators.com and refer to their sizing charts. Lots of good info there.
