No problem, just wanted to clarify! I don't think you mean 'in series', but rather in parallel, but be VERY CAREFUL! Many (perhaps MOST) power supplies can not be connected in parallel without damaging one or both of them. Make sure that the manufacturers directions specifically say that this can be done and follow the instructions carefully! Are you sure you need 100 Amps? and if so, 8 ga wire is probably not big enough.
