FRITZ!Powerline 530E – Service - Knowledge Base
Extending FRITZ!Powerline connection over an electricity meter, fuse box or ground fault circuit interrupter (GFCI)
As a rule, a FRITZ!Powerline network functions even over an intermediate electricity meter, fuse box or ground fault circuit interrupter (GFCI). You only have to take the additional conduction paths to and from these devices into account so that you do not exceed the maximum range of 500 meters over your power mains. The connection between the FRITZ!Powerline adapters is encrypted with a unique network password (AES 128-bit), thus protecting it from unauthorized users.
