Question:

Do you have to pigtail the grounded conductor before installing devices? In other words if you install a stab type receptacle and a short occurs breaking the device tab the grounded conductor would be lost. Please support with NEC articles. Thank you

Answer:

Hey Jeffrey thanks for your question. Device connections cannot be used for the continuity of grounded conductors of multiwire branch circuits as stated in 30.13(B).  Branch circuit, Multiwire  is defined in Article 100. A "pigtail" or "loop" method could be used.
