We present measurements of the inclusive semileptonic branching fractions of charged and neutral B mesons using 20.6 fb[sup -1] of data measured at the[Upsilon](4S) with the BABAR detector. Events are tagged with a fully reconstructed hadronic decay of a B meson. The correlation between the flavor of the tag B meson and the electron charge allows the separation of prompt semileptonic B decays and cascade semileptonic charm decays. We obtain the preliminary inclusive semileptonic branching fraction of charged B mesons b[sub+]= 0.103[+-] 0.006[+-] 0.005, neutral B mesons b[sub 0]= 0.104[+-] 0.008[+-] 0.005, their average b= 0.104[+-] 0.005[+-] 0.004, and their ratio b[sub+]/b[sub 0]= 0.99[+-] 0.10[+-] 0.03.
