The Draka boxes are crap we did away with them a while ago. Same issue, nuisance trips that had to be reset after hours and weekends of course. Good for the Duty Mechanic but bad for the customer. We have been using the white boxes that CED sells. I think the company is "LT" something. I'll find out the name and post it here. We have had no problem with these and they're easy to test for the inspector.
