Detachment of the box cover of the electrical panel is needed when conducting a well performed home inspection. That way, the inspection in the panel interior will be easy but it must be done carefully. It is the responsibility of a New Jersey inspector to check internal connections, breakers, wire size, grounding, wire type, panel and box condition and of course, the main breaker. Rusting in the service panel is a common circumstance or problem that people usually encounter.
Rainwater is always the main reason why there is the presence of moisture in the electrical service panel. Normally, electric meter or service drop can cause main problems inside the panel boxes. Water can move towards the interior of the insulated electrical wire and finally lodge itself inside the panel box by using the electric meter or service drop as a vehicle or conveyance.
Rain water, as the common and main reason moisture is inside the electrical box panel, has its way of getting into the panel and start initial rusting that will eventually develop into a serious corrosion problem. It usually happens when a part of the electric meter or the service drop is disturbed but has not been properly resealed. Water has the tendency to drip along these lines and find its way towards the panel.
Heavy rusting or decaying connections of the service entrance wires, wiring connections on circuit breaker terminals or individual fuse terminals, neutral or ground bus bars or connectors are described as serious corrosion. Peeling on metal panel components or other uncertain conditions are present in such instances.
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 electrical panel box vulnerability lies on its bottom where water is likely to be found. On occasions like this, removal of the panel cover is sound judgment, but it must be done carefully to avoid unsafe eventualities and hazards of electrical shock.
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.
Fortunately, its an amazing coincidence that service panels are usually installed in the corner of a basement, exactly where water may be stored outside from a faulty downspout. On a normal modern house with a single downspout at the front and rear roof edges, a service panel and a downspout will eventually find each other sharing a damp corner.
In general, the electrical panel box vulnerability lies on its bottom where water is likely to be found. On occasions like this, removal of the panel cover is sound judgment, but it must be done carefully to avoid unsafe eventualities and hazards of electrical shock.
