I am involved with providing temp power for an outdoor event. Figured some here would find it interesting. Plus I am board hanging out.
We have two gensets on site.
This is the smaller one, in Pic 1 you can see the generator output, L1, L2, L3, N on left, EGC and GEC on right.
From there a set of 2/0 feeders run to this tap, here we tapped into the 200 amp feeder with cam lock 'T's into a 100 amp stage type plug
That 100 amp single phase tap feeds this distribution box, this one takes the 120 volt 100 amp feeder and runs it through 20 amp fuses to 5 single outlets
In other areas we used this nicer box that does pretty much the same thing but has breakers instead of fuses
The 2/0 feeder keeps going, makes a road crossing
From there we tap at 200 amps to another kind of distro box, this is also single phase but 208/120. There are breakers in it and from there we run MWBCs out to outlets. Leaving this box are 10/4 SO cords that run out to boxes that break out the twist lock MWBC into standard 120 volt duplex outlets at the tables.
