Adding a CE1015E 15A 1 pole breaker to an existing CDP panel
The CE1015E breaker is obsolete.
Alternative breaker is an FFGP16015 with FFCMH mounting kit. Both breakers are rated at 18KAIC at 600V. Up to 6 FFGP breakers can mount on this hardware kit. Only FF type breakers can mount on this hardware and it takes both sides of the panel.
