Whem I asked the electrician about installing my Wattgate receptacle which I use he mentioned something about a special red plug as opposed to anything else for the separation of the neutral line.Find another electrician,.... he is scamming you. Red receptacles are used in the electrical industry to signify the outlet is fed from emergency power. The only difference between say a white recept and a red recept is the color of the face plate. Example, a Hubbell HBL8300H has the same guts and body whether it is red, white, ivory, brown, black or what ever....
Your Wattgate recept is made by Hubbell and is a very good recept.
