With the introduction next year of the new electrical code requiring new homes, and all electrical renos to have AFCI’s everywhere, Schneider Electric are introducing to Canada the Plug-on Neutral panels for the Square-D and Homeline panels.
These do not need pigtails for the AFCI’s. They are also going to introduce the person friendly combination AFCI/GFCI that detects ground faults at 5mA.

Don’t get caught calling out these AFCI’s as defects because they have no pigtails.
