A Richard Gray’s Power Company will have its full effect when plugged into the other receptacle.
Let me describe an unusual application of a Power Company: I was living in an old house that had several 120 volt window air conditioning units. The compressor was going bad on one unit, such that it would trip the circuit breaker every time it tried to cycle on. I didn’t feel like buying a new air conditioner at the time, as we were moving soon, so I plugged a Model 400 unit into the other receptacle. The compressor tripping was ELIMINATED, but returned soon as I unplugged the Power Company. So it remained in place until we moved,
I’m not an expert on everything that’s available in the world of power conditioners, but I bet there aren’t many that could do THAT.
