Depends on how well the feedline is installed and if it has common 
mode currents.

I run 120 volts out on cables, but I:

1.) Fuse them at low current. 

2.) Isolate them through a isolation transformer.

3.) Have a plug on the feed of the whole setup, so it is not part of 
the house wiring.

I run all my wires through the same pipes or trenches, and have no 
noise problems.
