  Baryon Chiral Perturbation Theory (BChPT) combined with the 1/Nc expansion is
applied to the SU(3) vector currents. In terms of the xi power counting linking
the low energy and 1/Nc expansions according to O(xi) = O(p) = O(1/Nc), the
study is carried out to next-to-next-to-leading order, and it includes SU(3)
breaking corrections to the |Delta S|= 1 vector charges, charge radii, and
magnetic moments and radii. The results are obtained for generic Nc, allowing
for investigating the various scalings in Nc.
