Visio Electrical Circuit diagram symbols should conform to the NEC codes as published by the NFPA.
Visio 16 Professional: The Electrical Circuit symbols do not conform to the NEC codes as published by the NFPA.
Please change the symbols to conform to those standards. Otherwise, Visio is useless. We have to turn to other software.
