LA302 - For 120-250 V, Single Phase,
3 Wire ServiceRated voltage 125-250 Volt, three wire service. Used when two hot wires of a single-phase system are to be protected.
INSTALLATION:
Fasten arrestor in place. Use a Delta mounting bracket, part # MB, a pipe strap, or a knockout hole. Connect the black wires to the hot line at any convenient point load-side of an existing fuse or circuit breaker. Connect the white wire to an existing ground system and the grounded metal framework of the equipment to be protected or make a ground source per NEC Article 250.
