Yes it can. Basically the "D' stood for dual, meaning plug-on and bolt-on on the same bussing.Does anyone know if this panel can take bolt in as well as regular QO breakers, has bolt in now but looks like it would accept plug in QO.
You aren't getting one at HD that will accept bolt on breakers. Straight QO is a loadcenter that is a panelboard already installed in a cabinet. NQ - is the commercial/industrial line that you can custom order various features/options, once you build the panel then you need to select a cabinet it will fit in. As Jim mentioned used to be NQO, NQOB and NQOD, but now is only just the NQ line that accepts both plug on and bolt on breakers.I've never seen a panel that could accept both. Buy a QO at HD and try it.
