for maximum branch fuse and circuit

breaker ratings. Select the motor branch circuit protection device that complies
with NFPA70 (NEC) or NFPA79, and any other governing regional or local
codes. The installer shall observe the product nameplate markings and not apply
the ArmorStart LT where the maximum perspective short circuit current is
exceeded. The ArmorStart LT shall be applied to a solidly grounded WYE power
distribution system that does not exceed 480V AC, 60 Hz or 400V AC, 50 Hz.
