Widths of magnetic islands induced by finite plasma pressure are computed for the Heliotron-E configuration (Phys. Rev. Lett. {bold 53}, 2242 (1984); Nucl. Fusion {bold 27}, 895 (1987)). Equilibrium beta limits are obtained from the criterion of island overlap. Earlier experimental observations on internal disruptions in Heliotron-E are revisited.
