Use side, electrical location are well spaced, allowing to really use all taken even when you have transformers.
The site dedicated to the CPL is also a good idea since otherwise the CPL does not pass through a surge protector socket.
But this location is not protected from the sudden, it goes without saying.
Side RJ11 (Phone), nothing special. Too bad we did not RJ45.
Who can do more can do less but there was the least.
However, for the protection of TV, what idea to have put a hold different size between the input and the output of the circuit.
It has two plugs, but one wider than the other. So, conventional TV cables do not fit. I had to buy an adapter male / male for plugging the TV on.
This may correspond to a standard, but in any case, it is not practical at all.
Ultimately, even if I do not have undergoes lightning attack on my home since I have these strips, I am satisfied, but their implementation could be greatly simpler.
