[RFI] Large ferrite chokes on power cables

[nlsa at nlsa.com]

Dear friends,

If I suspect that RFI is coupling to the 200A service entrance that feeds my
solar panel inverters.  Is it feasible to install a ferrite choke on this
big cable?  Besides the obvious need to be large enough to fit around the
cable, what other factors need to be taken into consideration?  I suppose
that the 60Hz AC current through the cable imposes come requirements on the
ferrite core. what are they?

Thanks,

Michael
