I think you can use either single 3-phase (usually 4 conductors + PE) LISN or two single-phase (2 conductors + PE) LISNs whichever you like, although I would prefer to use a single 3-phase LISN. BTW, there maybe confusion with the term "single-phase LISNs" here. Is it LISNs commonly used for single-phase AC supply? Or is it LISNs for an single power supplying conductor?
