Power Line Filter 3Phase 36Amp Neutral Lines
I recall seeing a formula for derating a 3-phase filter for single-phase
use; divide the current rating by the square root of three. I have a
200 A 3-phase Y that's UL rated for 480, and I'm tempted to filter the
whole house -- after the main fuses. Heh.
I'll probably just use a smaller one on the branch circuit that runs the
shack; the Big Guys are labelled at 2A of leakage current -- and the new
Smart Meter might bill for reactive VA.
