A:No, we suggest not install at big building. Please refer to the following points for more understandings:
1. PL-510W must build in the same power loop, if the loop is different that can cause disconnect. Based on experience, the big buildings will have many different loops.
2. PL-510W maximum distance is 300M, if it is over that can cause signal failure and disconnect.
3. IF the powerline is old or broke and cause signal failure and disconnect.
4. The maximum number is 8 PCS at the same power loop.
