That is the big advantage of staged motors but I would hate for you to have a fire because you were over the max amperage of the lines in the system.
I used 8 115923 motors recently in a bench and used 20 amp 220 type breakers (one motor on each leg). The specs say each of the motors will pull over 10 amps but without a load they seem to be fine. I will post more info once we get out latest fixturing set up and we are moving air. I will be doing some 4 cylinder air distribution work and we are fabricating the air connectings into the intake manifold. The test will be in the "blow mode" and the engine has orifice plates in each bore to read the given distribution per cylinder.
