Product FAQs
8 answersCan I install the Eaton NGS308035EC in older Cutler-Hammer panels?
Yes, this Series G NG-frame breaker is backward compatible with legacy Cutler-Hammer switchboards, motor control centers, and Series G panelboards that accept NG-frame breakers.
What does the C suffix indicate in the NGS308035EC catalog number?
The C suffix designates that this is a 100 percent rated circuit breaker. It is approved to carry its full 800A continuous current rating, unlike standard breakers which are typically limited to 80 percent of their rating for continuous loads.
What type of trip unit is installed in the NGS308035EC?
It is equipped with a 310+ electronic trip unit featuring adjustable LSG (Long-Time, Short-Time, and Ground-Fault) protection settings to allow for precise selective coordination in your electrical system.
Are lugs included with the NGS308035EC circuit breaker?
No, NG-frame breakers typically feature stud or tapped pad connections out of the box. Mechanical or compression lugs must be sourced separately based on your specific wire size and conductor material.
What is the difference between the NGS308035EC and the NGS308033EC?
The NGS308035EC includes ground-fault protection (LSG trip functions), whereas the NGS308033EC only provides long-time and short-time (LS) protection. Both are 800A, 100 percent rated NG-frame breakers.
Is the Eaton NGS308035EC suitable for reverse feed applications?
Yes, Eaton Series G NG-frame circuit breakers are suitable for reverse feed use, allowing line and load connections to be wired in either direction without compromising safety or protection.
What does the NGS prefix mean in this Eaton catalog number?
The NGS prefix indicates that this is an NG-frame circuit breaker with a standard interrupting capacity, which provides 85kAIC at 240VAC and 50kAIC at 480VAC.
Is the NGS308035EC HACR rated?
Yes, all Eaton NG-frame circuit breakers are HACR rated for use with heating, air conditioning, and refrigeration equipment.
