Rust and Corrosion on Electrical Panels–the Hazards and Causes
Issues that may signify malfunction or hazardous conditions involve inconspicuous tarnish or corrosion on each component ; signs of overheated electric ground and balanced wiring at a corroded panel bus, and too hot electric branch outlet connecting lines which may or may not be due to a corroded circuit breaker that failed to catch, or more breakage at the connections of the service front wires, at wiring connections on outlet breaker fuses or specific fuse terminals, at neutral or ground bus bars or connections; or rust at the origin of electrical panel enclosure itself.
This could result to very hot electric branch circuit wires which may or may not be due to a rusty outlet breaker which failed to trip, or additional breakage at the connections of the service entrance cablings, at wiring connectivity on circuit breaker fuses or separate fuse terminals, at balanced or ground bus bars or connectors; or corrosion at the origin of the electrical panel enclosure itself.
Sources of liquids and dampness entry were: through panel frontal transistors wires which have been outdated and also broken, or which have been inappropriately sealed at indicator containers or structure sidewalls; with liquefaction coming from excessive interior humidity degree; and coming from other building leakages or surface water that passed along the house partitions wherein panel enclosures have been attached.
Origins of fluid and moist entry are: through service frontal conductor cables that were outdated and exfoliated, or which are improperly sealed at indicator buses or house walls; with water buildup coming from high interior moisture levels; as well as coming from other building leaks or external liquids which passed along the building walls wherein panel enclosures are mounted.
This is why you should have your electrical panel boxes checked for any rust or corrosion. You can hire a local technician to check if the wires are damaged, and if necessary, have him change everything. What an experienced electrician normally does is to inspect, check and observe the electrical panel.
After a study on the cause of corrosion and rust, he can evaluate and give you an assessment on what must be done. So far the most common source of water entry in service buses and can be correlated along with the inclusion of an above-ground service entry wirings coming from outside, via the structure sidewalls, towards enclosures that are situated in underground rooms or at a spot at the lower part in comparison with the factor of intrusion of the electrical wires via the house wall.
So far the most common cause of water entry in service enclosures and can be connected together with the inclusion of an overhead electrical entry cable from outdoors, through the house sidewalls, into buses that are positioned in basements or at a location at the lower part than the factor of penetration of the electrical wires by means of the building wall. The most typical mechanism in which wetness entered such panels was coming from roof/surface overflow, causing basement water intrusion and high interior humidity levels that in turn led to condensation.
It is important to have your electrical panel boxes checked once a year. You can check your yellow pages for electricians, or better yet, ask for recommendations from your family or friends. A reputable electrical professional should be able to assess your property for any big leakages, and how the other conditions in your house affects the status of your electrical panels. Always remember that it is best to keep your wirings new and safe, because faulty wiring is one of the most common causes of household fire nowadays.
