We can all do it. I accidentally switched on the power to my DCC system last Friday which was on the desk attached to a test track, sitting on the test track at the time was a pcb circuit board for a DCC booster complete and in working order, The DCC tripped but that wasn't quick enough to avoid any damage considering it takes 1.5amps to operate the trip
Nothing let the smoke out but a few Ic's no longer work, parcel force bringing the chips tomorrow
