Inspection of the Electric Meter and Service Entry Cable

Frayed service entry cable at electric meter (C) Daniel FriedmanLet's start the steps of inspecting a building's electrical service at the meter and SEC cable.

What can se see that is important, without touching or testing anything? Quite a lot.

Pay special attention to water entry at the service entry cable, at the top of the electric meter enclosure, and at the wall penetration where the SEC enters the building as these conditions can send water into the electrical panel where corrosion creates unreliable equipment and water is a hazard.

Fatal Shock Hazard Warning: Inspecting electrical components and systems risks death by electrocution as well as serious burns or other injuries to the inspector or to others. Do not attempt these tasks unless you are properly trained and equipped.

See ELECTRIC PANEL RUST for a study of water entry, rust, and corrosion in electrical panels presented at the 1992 IEEE Holm Conference.

SeeSHUT DOWN EQUIPMENT, WHEN TO

In some cases "appropriate people" includes not only the client and building owner, but also building occupants.

Watch out: the very loose electric meter shown in our photo risks fire or death by electrocution simply by touching it. A trained electrician or electric utility worker might pull the meter off of a meter base as a means of cutting electrical power into a building in an emergncy.

But in this case that manuver is dangerous Notice those screws protruding from the back of the meter? Imagine touching it when a screw falls into the meter and causes a dead short between the service entry cable and the metal electrical meter base or box.

To repair this electrical meter safely power should be dropped at the overhead masthead.

These electrical inspection suggestions are not a complete inventory of all electrical safety procedures nor of all electrical components that should be inspected; these notes focus on identification of conditions that may present special electrical hazards for the electrical inspector.
