Adding a CE1015N 15A 1 pole breaker to an existing NHDP panel
The CE1015N breaker is obsolete.
Alternative breaker is an FFJP16015 with FF22NHDP mounting kit and MHMHDP mounting screws. Both breakers are rated at 25KAIC at 600V. Up to 6 FFGP breakers can mount on this hardware kit.
This will mount in 22 inch wide NHDP panels only. They will not mount in the older 20 inch wide NHDP panels.
