20.Where a 2-prong is encountered, replace the plug with a properly grounded 3-prong receptacle in accordance with the National Electrical Code, local codes and ordi- nances. To ensure a proper ground, the grounding means must be test- ed by a licensed or certified electri- cian.

21.Use only 3-wire extension cords that have a 3-prong, ground type plug,
