  A preliminary result on the study of the inclusive electron spectrum in B ->
X_u e nu decays above the kinematic limit for the dominant B -> X_c e nu
transitions is presented. This study is performed at the PEP-II asymmetric B
Factory, where B meson pairs are produced in the decay of the Upsilon(4S)
resonance. For the electron momentum range of 2.3 - 2.6 GeV/c in the
Upsilon(4S) rest frame, the partial branching ratio is measured to be Delta B(B
-> X_u e nu)=(0.152+-0.014+-0.014) 10^{-3}.
