Okay so we are trying to figure out how big (power wise) of a generator we need for an outdoor charity event. The event is about 2 months away, but we need to spec the genny now. Unfortunately, the genny will be powering all of the staging as well as regular power needs for concessions, radios, tvs, ect. We also don't have the final specs for the staging and won't for at least a month. From the specs I have we will have 5-10kW of MLs, a sound system for a large outdoor event, and some video from a projector. The 'other' not technical stuff will probably need 10kW to be safe. How big of a generator do we need? Do we need some kind of seperate (intermediate) breaker between the genny and the 'other' stuff so if they put something bad or overload it we don't lose the power to staging? Note: We will have someone there qualified to do the hookup, so that's not an issue.
