Danger of Water in Electrical Service Panels

By Lloyd Ramirez


In moving to a new house, inspection of the electric service has to be considered and conducted by a high quality residential maintenance inspector, whose assessments are often made at the time of sale of a second handed house to ensure its safety. Generally, these observations can supply a database of field performance of domestic electrical system parts that may be helpful for the progress of amendments in both the parts and their associated qualification requirements.

Actually, expert home inspectors offer a unique perspective on field setbacks: in performing a comprehensive review of a building's structures and parts, an assessor may realize familiar exterior or interactive causes of damage or deterioration. The surface rust on panel enclosure parts and other steel components in the panel is notified as light corrosion. Invisible evidence of malfunction, wet parts, arcing, burning, history of repairs, that safety components such as fuses or circuit breakers appear at likely risk of break down.

Corrosion and rust is mainly caused by leaks through the base of basement walls wherein the panel box is located. As an instance, everyone must be aware of the danger once the service panel may get wet and malfunction.

This way, the service wire works like a sealed tube that serves as a conveyance that helps moisture to get into the electrical box panel. Rain water driven by wind can also infiltrate deteriorated or damaged main service cable. The problem even escalates as water attacks the insufficiently sealed where the service drop and electric meter entered.

Water seeping and infiltration through foundation walls of the basement where the attachment of panel box is located have a lesser ability to cause corrosion. Potential damage can still be caused by these and hazards are likely to come up. Stone, concrete or masonry walls are not ideal places to attach the panel boxes directly. Condensation, as a result high levels of moisture at home can cause corrosion to the panel box.

Causes of corrosion which are common but have a lesser magnitude in terms of damage water penetration or seeping on and through foundation walls where the attachment of the panel box is usually connected.

House inspection aims to inspect and check water infiltration such as this and other damage on the electrical panel. The terminals and circuit breakers rust and corrode as a result of moisture in the panel box.

The very common procedure by which moisture entered these panels was from surface runoff, causing basement water entry and high indoor humidity levels which in turn lead to condensation. In several other cases there were indications of water entering the rear of the service enclosure at points of contact with the basement wall, even when the enclosure was actually attached to a wood which themselves were fixed firmly directly to the base.
