[QUOTE="RustySpoons, post: 1073700, member: 412012"] These days they use a SMPS PSU, with quite a high floating voltage across the chassis for EMC/RFI Filtering. Across different phases this can be problematic and nasty. Drop a neutral on the incomer, (most supplies are TN-C-S) And all hell breaks loose. One reason why LNB's shouldn't be shared with a neighbour in a street, not only if they are on a different phase but earth potentials/faults. [/QUOTE]
