Are there switches for “phase” and “zero”?
In the village there is a “bad” zero, the off-light devices are dimly lit or blink and quickly fail. I can not find on sale a two-key switch for two inputs (all have one input, 2 outputs). Question: are there switches for the “phase" and the "zero", or is there another solution to the problem? (except for a solid ground loop, there is one on OHL 0.36 through 3 poles = 150m, my last pole on the line).
