Well, I've noticed that some of those commercial boards aren't getting cleaned regularly, a good wash now and again may be a good thing

 

[DurhamSparky]

so true...

EXTREME db washing!!

Tell us more, like what was the source of the water?? Were all the breakers saturated in or by the water?? If so, you may want to consider changing all of them, residue from the drying water can be conductive, thereby rendering the tripping function(s) inoperative. Or possibly at the very least, will corrode any spring mechanisms...

Most interior DB panels have very low IP values, and will be almost impossible to protect against any further water accidents. So i take it your talking about sealing holes and crevices that are present in the back wall these panels are mounted on??

there is a 2" drain hole in the bottom!!

A few years ago I got called to a GE System4 distribution panel. It was under 2’ of water and still live!

Steam coming from the bus-bars as the water boiled between the bars. But still LIVE! It took a bit of cleaning up but nothing had to be replaced. All the lower switches were fused, not a one blew. It was like entering a sauna when I went in to the room!

PS I was wearing Wellingtons and insulated gloves J a bit silly really as all external metal work is earthed.
