Will this panel take model Q115DFP Arc fault breakers

Example: I have looked at the manual and can't figure out what I did wrong.
Asked by: Jim
The Q115DFP is not an arc fault breaker, but a dual function AFCI/GFCI circuit breaker. Yes. this panel will accept them.

What is the size of this breaker box/

I need the measurements of the breaker box.. I lost the cover and need to buy a whole breaker box just to use the cover on my existing one. So I have to buy the same breaker box I have so the cover can fit on it. Unfortunatelly there is not label sticker with the name of the brand, but it looks like this one.
Asked by: Jackie
Under the specifications for this panel the height is 27", width is 16" and the depth of the bix is 5". I don't believe the dimensions provided because I know this loadcenter is manufactured to fit between 16" on center studs for a flush installation in a typical 2 X 4 wall. Unless your existing panel is just a few years old you'll probably not find a new panel with a cover that will fit your existing panel. Be prepared to change out the entire panel.
