how do i wire a 3 prong range (red,white, and i can't tell the other color it just has a block where all 3 wires meet and a washer type sticking out to screw to oven) and i want to wire it to a 4 prong 220v outlet right behind it. i got a 220v plug and 6-4 slow cord to use with 4 wires. red,black, white, green. which wire goes where? i have a good idea but double checking with u guys just to be safe. i was told nuetral wire is sometimes not needed?? plz help. any help +++++
red positive .black neg .green earth. not sure about white turn of from mains and check connection wires at back of plate it can be screwed out .that will let you be safe and sure.never seen white on any wiring system.always red black and green i have seen and wired my own oven with those three only/.
