Does it matter which way you wire a plug?
Many devices only care about the relative potential (i.e. voltage) between the two wires, in that case the polarity (i.e. direction it’s plugged in) doesn’t matter, since flipping the polarity has only one effect of the relative voltage: it flips the sign, but AC has a type of symmetry that means that flipping the sign …
