Does PLC work with surge protection?
If all the equipment is downstream from the same surge protector, then there is no problem. On the other hand, the surge protector contains a filter which will block the frequencies being used. In this case, it will not be possible to communicate between the terminals which are plugged in on either side of the surge protector. We would always recommend that you test the equipment to see how it behaves, as this can vary from one model to another. However, there are surge protectors which have a special PLC plug (Merlin Gerin).
