Bypass Isol ATS
Bypass Isol ATS
Out here in CA a BP isolation type ATS is code required in health care facilities. They are also favorites in large data centers. They facillitate ease of troubleshooting and maintenence. Even though the make -before-break type allow for seamless interruption of power during switching, hospital people are nervous and wouldn't allow servicing during critical hours and we have to work them in the early mornings.
Brian is correct, untrained people can do a lot of damage to the mechanisms during startup or maintenance and we usually have to come in and straighten out the mess.
