Electricians in Los Angeles need to examine the meter and meter base and should take them into account when determining service ampacity. The elements to consider are:
– The size/rating of the service entrance conductors.
– The rating of the panel.
– The rating of the main breaker, if any.
– The rating of the meter base.
– The rating of the meter.
The weakest or smallest of these five items will determine the service ampacity of the system. This inspection will also determine whether or not all parts of the system are compatible with each other and proper for the installation. There are other good reasons to look at the meter base and meter during your inspection. A local electrician in Los Angeles at United Plumbing Heating Air & Electric explains that,”Occasionally one may discover other meter defects or concerns.”
- Moisture or water inside the meter face and/or rust on the meter base, such as leaks at the service entry cable or other meter base components. For example, rust at the bottom corners of the electrical meter box.
- Missing knockouts on the meter base – openings into the electrical meter base.
- Broken or cracked conduit at the electrical meter or meter hubs
- Loose connections of the meter base, including meter pulling away from the building wall and loose mounting screws
- Inadequate fastening of the meter base and/or mast to the building.
- Evidence of tampering at the electrical meter, such as a locking ring seal that has been cut and not replaced by the electrical utility company.
- Evidence of burning or arcing at the electric meter connection mounts. This condition is unlikely to be visible unless the meter is actually removed from its mounting base.
Watch out: this step should be performed by a licensed electrician. It is not within the scope of a visual home inspection.
