Will the powerline signals pass through different phases? Would a phase coupler help?
In some cases, the powerline signal will be able to pass through a different phase because of mutual inductance. However, testing has shown that the strength of the signals is very weak and eventually the performance goes down, until the communication is completely lost. A phase coupler is an ideal solution to this problem; installed in the power distribution box by an electrician, the phase coupler joints all phases together allowing signals to be injected directly into the different phases.
