Product FAQs
6 answersWhat older Cutler-Hammer breaker does the NGC308033E replace?
The NGC308033E serves as a direct drop-in replacement for the legacy ND308033 molded case circuit breaker. It shares the same physical footprint for mounting in Series G and Pow-R-Line C panelboards.
Does the NGC308033E include mechanical lugs for wire termination?
No. This specific catalog number is configured with imperial tapped line and load conductors, also known as stud or tapped pad terminals. If your installation requires mechanical wire lugs, compatible NG-frame lug kits must be sourced separately.
What protection settings are adjustable on the Digitrip 310+ LS trip unit?
The LS configuration provides adjustable Long-Time (L) and Short-Time (S) pickup and delay settings for precise coordination. It does not include adjustable Instantaneous (I) or Ground Fault (G) protection functions.
Do I need to purchase a separate rating plug for this 800A breaker?
No. The Digitrip RMS 310+ trip unit installed on NG-frame breakers features selectable long-time delay and pickup settings directly on the face of the unit, eliminating the need for interchangeable rating plugs.
Is the NGC308033E rated for 100% continuous operation?
No, this breaker is standard 80% rated. Continuous loads should not exceed 640 amps (80% of its 800A nominal rating) in accordance with standard National Electrical Code (NEC) sizing rules.
What equipment is the NGC308033E designed to be installed in?
This 800A bolt-on breaker is engineered for use in Eaton Series G panelboards, Pow-R-Line C panelboards, switchboards, and motor control centers.
