Recommended Upstream Protection

CAUTION
HAZARD OF FIRE Connect only to a circuit with the below specifications. Connect to a circuit provided with a 175 A branch circuit overcurrent protection maximum in accordance with the National Electric Code, ANSI/NFPA70, and the Candadian Electrical Code, Part I, C22.1. Failure to follow these instructions can result in injury or equipment damage.

NOTE: Overcurrent protection is to be provided by others and marked with its function.

NOTE: For IT systems or resistance grounding systems, a 4-pole circuit breaker must be installed.

NOTE: For local directives which require 4-pole circuit breakers: If neutral conductor is expected to carry a high current, due to line-neutral non-linear load, the circuit breaker must be rated according to expected neutral current.
