Branch Circuit Protection
The ArmorStart LT is Underwriters Laboratory (UL) Group Motor listed. Refer
to the product Specifications
, Chapter 6 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.

ArmorStart LT is UL Listed for use with 14 AWG wire or preassemble power
cable. Refer to your local electrical code(s) when applying 16 AWG wire or cable
in a motor circuit.
ATTENTION: Select the motor branch circuit protection that complies with the
NFPA79/ or NFPA70 (NEC) and any other governing regional or local codes.
WARNING: Do not install the ArmorStart LT where the maximum available
fault current exceeds the product rating.
