US Classification:

361624, 361622, 361631, 361656, 361664, 700286, 200 5032, 200 5033, 307 64, 307126

Abstract:

The present invention relates generally to a load center. More particularly, the invention encompasses a generator ready load center (GRLC). The present invention is also directed to a novel generator ready load center (GRLC) that operates as a standard load center but is ready to accommodate an automatic transfer switch (ATS) for a standby generator, or a manual transfer switch (MTS) for a portable generator. Further the generator ready load center provides an automatic and manual transfer between primary and secondary power sources. The generator ready load center solves the problem of dangerous back-feeding between the primary power source and the secondary power source.

Abstract:

A parallel electric service system including a combination load center is disclosed. More particularly, the parallel electric service system encompasses a combination load center adapted to receive power from a utility power source and a parallel power source such as a solar module, wind turbine, fuel cell, or the like. Power may be supplied to electrical loads of branches of the system by the utility power source, parallel power source, or both. The system also provides electrical usage metering and allows electrical power to flow back to the grid. Methods of connecting parallel power sources in the parallel electric service system are provided, as are other aspects.
