I can understand, been there. I think what gets me the most is electrical cords and water. At first, I left all the wiring and power strips to my husband, let the pro handle it (15+ yrs. experience) that should count for something, thank goodness for GFIs'. But always test for water leaks before anything, bulkheads usually come with a rubber washer to make a good seal and that's to prevent leakage. Sometimes taking slow is better.
