  • Experience with powering show with Generator

    We have been asked to play an outside show that will be powered by a generator. Does anyone have experience with this? What size generator would I need to power all amps, sound system, and lights? They say that they have 6000watt generator, but I think that that may be way to low in wattage needed?

    All this depends on what gear you own. You'll have to do a load calculation in order to know. I will say this, small to Medium setup, should be OK, so long as you don't go crazy with lights. Use LED's.

      I ran a 7000w FOH with monitors and led lighting on a 6500w generator. It worked but if I had a choice I would rather have had a real genset around 20kw to handle spikes and sag's. The 6500w generator we were using was a really nice. The backline was running off it's own generator of the same model. The client probably paid more renting the 2 small generators than it would have cost for the right one to begin with.

      Here is a shameless plug for my local guy so you will know what your looking for.

        Are there any safety issues with running multiple Gennies, other than tying the grounds into a ground rod?

          Neutrals must be bonded to grounds, earthed, and the ground system must be bonded together.

            Make sure to ask how loud that generator is. Some are quiet, many are loud and better suited to a construction site.

              Hmmm.....I thought that most Neutrals were not attached to ground in a Genny System; Honda has a non attached Neutral..

              From the Hondas EU3000i Manual:

              "System Ground
              Honda portable generators have a system ground that connects the
              generator frame components to the ground terminals in the AC output
              receptacles. The system ground is not connected to the AC neutral
              wire. If the generator is tested with a receptacle tester, it will not show
              the same ground circuit condition as for a home receptacle. "

              Ok, so under that parameter, how does one bond the neutrals? Where is the neutral going in this scenario? Is it floating? Hmmm...

                Ive ran 800w sound system, a 450 watt bass and a 120 watt guitar amp off one of those 1000w tiny Honda generators with no problems whatsoever.

                Also as an added bonus they are so quiet that standing over the top of it you can talk in a normal tone of voice.

                  I'd check to see if the genset provides 6000 continuous watts or only under a peak (surge) load. If it is peak, a continuous rating might be less than 5000 watts. Add the loss from the long extension cords needed to keep the generator noise away from the, well, the generated noises, and you may not have enough capacity.

                      There should be some Honda application notes regarding required grounding/bonding of portable electrical systems. They fall under the "seperately derived" systems of the National Eloectrical Code as well.

                          Ive done it for several times when we had to provide our own power for an event called Bloomsday. The generator was running for 5 to 6 hours at a time, none of the amps were dimed or anything(we're asked not to be over poweringly loud) but the generator didnt stumble, or bog down.

                            I've done stupid things several times and it turned out ok... I just didn't know how stupid they were or how lucky I was at the time. I do now.

                              Yeah, But It's all a Pipe dream. How does one Properly bond a ground in the Playa? Which is dry, slight alkaline, slightly conductive, and almost impossible to drill into? I do bring a monster drill bit and I can drive a Rod 5-6' down. I plan to bring copper this year, in years past I used Rebar. But I realize I have a lot to learn....
