A meat department is a "washdown" area. Only because the hired help will hose the walls. What type of cover (even though rated) is actually washdown rated. I've seen W/P Covers even In-Use covers used and the devices don't last 1 year. Now, couple that with a GFI Recpt which will fail in a year, even if it not used and you have your next service call.
Its just not right! Even if it is safer for the employee.
