Classe CA-400 amp trips

Solidly, I'm using all XLR connections - NO RCA's.
I acquired a Monster Power Center HTS5100 and I thought it's causing the problem when my house's A/C or ref. current goes on.
Obviously, that does it for another expenditure.
As far as the DC issue, what can I do now, besides sending my BAT back to the manufacturer?

That slipper might have been worth something.
I'm trying a lot of things at this point - repositioning the units, switching interconnects (b/w VeraStarr, Synergistic Research). At first, I thought there was a loose connection but I disconnected each one and plugged them back a thousand times - didn't work.
This minor type of problem should not be happening in a high end expensive audio world.
My last option would be to waste my time sending the BAT 30SE back and take a blood pressure pill without a tune for a week or so.
