Jumpin' Jazz

THIS ARTICLE DESCRIBES THE OPERATE and maintenance of a low-voltage power s tern used to power a jazz café. This is not necessarily an important factor in the natio economy, but problems encountered and described herein may be representative of many small commercial operations, such as restaurants, grocery stores, drug stores, and similar sized shops. When engineers consider the design for commercial operations, the thought is generally on high-rise type office buildings or some similar facility [1]. What is important to remember is that, while there are probably more small installations than large capacity systems, the small shops do not normally have a maintenance crew for support. After reading this article, one should be left with the thought that we have a gap to fill. For this article, the term “café” will be used, even though it is not purely descriptive.
