(E) Phase Arrangement. The phase arrangement on
3-phase buses shall be A, B, C from front to back, top to
bottom, or left to right, as viewed from the front of the
switchboard or panelboard. The B phase shall be that phase
having the higher voltage to ground on 3-phase, 4-wire,
delta-connected systems. Other busbar arrangements shall
be permitted for additions to existing installations and shall
be marked.
Where does this apply to meter enclosures provided by the POCO? That is why it is very important the electrical contractor knows this and when the NEC picks it up, that it lands in the center termination per the NEC.
