Hey all,
We have a 150A breaker feeding 2 sub panels at our plant. Those 2 sub panels are full and have a certain rating on them for capacity in amps and lug rating(which I don't have on hand right now, but is irrelevant to my question). What I would like to know, is how do you go about determining the size of those sub panels (calculations)? How would you know, if you wanted to add other sub panel on a specific service breaker, whether or not that panel is the right size or not when compared to the breaker feeding that panel? Maybe its me not being familiar enough with the terminology, but there is a bit of confusion as to how one goes about determining all the appropriate information to size a panel from the service amperage, to the breaker size and so on. Any technical information on that subject would really be appreciated. Thanks.
