Check for downspouts diverters not discharging water far enough away from the house. Check floor lawn irrigation systems spraying water against the house foundation, and check for gardens or planters that are up against the house. These may be causing wet soil pressure problems for the structure.

A slab-on-grade foundation is a type of foundation consisting of a structural concrete slab poured onto the ground, but usually, there is a layer of gravel and a vapor retarder between the ground and concrete. View illustration of a slab-on-grade installation. No accessible space exists in slab-on-grade construction. Slab-on-grade foundations are popular in areas where there is a high water table. For example, there are very few full basements in Southern Florida. In general terms, a slab-on-grade foundation is poured on the grade or ground. complements of InterNachi @ www.nachi.org

What's an Arc Flash?

An arc flash occurs when a flashover of electric current leaves its intended path and travels through the air from one conductor to another, or to neutral or ground. It often happens unexpectedly and can be explosive but brief, or it can last seconds and be rather visually spectacular. It can cause a little damage or it can disable a system and require the replacement of equipment. An arc flash of any size is quite dangerous because its path is unpredictable; it will be attracted to the nearest item with the greatest conductivity, such as an unsuspecting rodent or house pet, or a person. An arc flash can cause a serious electrical burn or even fatal electrocution.

Many people use the name Romex® when referring to type-NM cable. Romex® is a trademarked name that has come into common usage for referring to plastic-covered wires, but type-NM just means "non-metallic" and also applies to other cable styles.

Moisture

A crucial point to always bear in mind is that water can be a very good conductor of electricity. Any panel that is damp or wet should NOT be touched or opened by an inspector.
