PZZ01 or simular for 300 amp

[zubinell]

I would like to install a blocking filter similar to the PZZ01. The PZZ01 only is suitable for a 200 amp service. I need a device suitable for 300 amps. Are there any suggestions? It is unfortunate that while X-10 offers an inquiry page to submit questions there is no response to questions submitted. Perhaps there are some other ideas available.

Thanks

I am not aware of any blocking filter larger than the PZZ01.

Here we have two panels.  The "Main Disconnect" panel powers all heavy 240V loads.  That also feeds a centrally located 200A "Distribution" panel that has the PZZ01 (actually a Leviton 6284).  All X10 loads are fed by that panel.
