Yeah i tested it when it when top enclosure panel and top sheet were on and water flowed off around the perimeter of the table to the floor. You will see on later pics with both panels on. This pic was taken during wiring and was posted to show pass through. The main enclosure at back also has a sliding top under the main top. In the unlikely event that liquid gets in the rig rcds should trip, if they dont then the house rcds / saftey switch should.
