Hi:
I asked Mike this and told me to come here.
Using as reference the 2002 NEC and Vol. 1 of the guide, article 230 indicates structures should have 1 service drop only, with some exceptions accompanied by an info plaque. Neither book explains why and that's what we want to know.
So, why is it that the NEC indicates that structures should have 1 service drop only? A friend says the main reason is safety, but we need a deeper explanation.
Also, the conditions or safety reasons that oblige the 1 service drop only rule, don't apply to multiple EGs in structures/buildings? I think the Special Condition of Emergency Power allow the installations, but we need a deeper explanation.
