No, we suggest you not to install at big building. Please refer to the following points for more understandings:
1. The PL-751 must be built in the same power loop if the loop is different that can cause disconnection. Based on experience, the big buildings will have many different loops.
2. The PL-751’s maximum distance is 300M. If it is over than that, it can cause signal failure and disconnection.
3. If the powerline is old or broken, it can cause signal failure and disconnection.
4. The maximum number is 16 PCs for one PL-751 after another PL-751 is in the same power loop.
