Which is Neutral / Hot Wire? (SPT-2)
I want to add a (single pole cord) switch to an electric blanket cord...
(because when plugged in, the power light is always on and the control unit is always too warm, even when blanket is off.)
...Directions say strip only hot wire. But wire is white flat flexible cord (SPT-2) no ribbing. How do I tell which wire is hot from the outside?
There is "printing" only on one of the 2 wires. Would that be the hot wire?
