Automatic transfer switches (ATS)
1. Transfer switches are required to be operated monthly [see NFPA 110(10), Sec. 8.4.6; see also: MSFC(15), Sec. 604.3.3].
2. This monthly test must consist of electrically operating the transfer switch from the normal/standard position to the alternate position and then a return to the normal/standard position [see MSFC(15), Sec. 604.4.1; NFPA 110(10), Sec. 8.4.6.1].
o In many cases, a “Transfer Test” switch or button is provided and can be used to perform this test.
