If you are talking about using a generator in the parking lot and running a cord to your pit I would bet that would not be allowed.

I'm just the messenger, I did not participate in deciding what size generator to rent to supply pit power. I can tell you that how running 5 or 6 pits off of 1 20a circuit at the WA Girl's Generation was taken into consideration when deciding the power needs. It did not present a problem there until someone plugged in their Leaf into one of the circuits.

You'd better hope no one plugs a vacuum cleaner in (~12amps).
Something like a vacuum cleaner will not be allowed to be brought in and certainly would not be allowed to be used.

I hope they can find a way to increase it, even if its only to like 6 amps per team instead of 4.
The current plan is to only allow charging 2 batteries per team at a time.

Again I'm just the messenger. If the power proves to be woefully inadequate the size of the rental generators will likely be revisited.
