@Porschev posted:I am running PH135 bricks. In all cases the PSX-1AC trips first and without a visible spark/arc. I have yet to have a PH135 breaker trip before or with the PSX-1AC. Before I installed the PSX-1AC's it would take quite a short to trip the PH135 breakers and through the years I damaged 2 TIUs. While it's only been a year, there has been NO damage to the TIUs since install of the PSX-1AC's.
What are your PSXs set at? The bricks set point is fixed, the PSXs are adjustable.
