Abstract: A surge arrestor cap can be manufactured with a cavity that is designed to mate with gas tubes directly, without use of a separate holder or spring clip. One end of the gas tube fits inside the surge arrestor cap cavity, and is held in place inside the surge arrestor cap cavity. Thus, access to the gas tube is provided by removing the surge arrestor cap, for example, by unscrewing the surge arrestor cap from the remainder of the surge arrestor assembly.

Abstract: An integrated transient voltage surge suppression system and automatic power transfer switch which includes a framework, an automatic transfer switch mounted to the framework, the automatic transfer switch being configured for electrical connection to a primary source of electrical power, a secondary source of electrical power, and a recipient electrical power load, the automatic transfer switch being configured to normally route primary electrical power from the primary source of electrical power to the recipient electrical power load, the automatic transfer switch being further configured to switch upon the occurrence of a predetermined switch condition such that the automatic power switch alternately routes secondary electrical power from the secondary source of electrical power to the recipient power load; and a transient voltage surge suppression device mounted to the framework and electrically positioned between the automatic transfer switch and the recipient electrical power load.
