mridgeelk Posted December 17, 2008 Report Share Posted December 17, 2008 Some breakers in this panel have a small amount of a white powder on the plastic next to the point of attachment screw, most evident on the fourth wire, the white used as a hot. A similar powder is evident in one of the drain valves in the crawlspace. I told my client that the valve likely dripped causing the buildup. The water is extremely hard which probably explains the buildup at the valve, but I don't have a clue what caused the deposit on the breakers. Any ideas?

hausdok Posted December 17, 2008 Report Share Posted December 17, 2008 Hi, Not sure about the valve. I've seen it before in areas that were dry. I've got a half-baked theory that it's related to certain chemicals being stored in close proximity to the panel. Is there a laundry in that basement with open boxes of detergent nearby? If so, was there a distinct laundry smell like bleach had been used? ONE TEAM - ONE FIGHT!!! Mike Quote Link to comment Share on other sites More sharing options...

When they're manufactured, the black plastic housing has a small open port just next to the wire terminal. This port is filled with a white plaster-like substance -- I don't know what it is or why it's there. Sometimes this substance breaks down and accumulates on the adjacent ledge just as it's doing in your photo. I've seen it a few times but never gave it much consideration before. Sorry I don't have more information for you. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
