in what i do, you size transformers and cable sizes for peak, if not more (aka. oversizing). say you have a 480v to 240/120v single phase 50kVA transformer. is that good enough? well you have to look at your loads to find out. yeah, i started out assbackwards on purpose because i've had clients say that's what they want without knowing their power consumption for that feed. same here. you have the power.....only how much power gets used is up to all the components and with all the components consumption added up wattwise is the ps then big enough?

unless of course you're LJ. then the component is big enough. the only person i know that can trump the dos XX most interesting man in the world is him.
