Adding a CE1020N 15A 1 pole breaker to an existing CDP panel
The CE1020N breaker is obsolete.
Alternative breaker is an FFJP16020 with FFCMH mounting kit. Both breakers are rated at 25KAIC 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.
