Transfer/Bypass-Isolation Switches

The automatic transfer switch is a key element in

any emergency power system. The importance

of the transfer switch increases as the need for

dependable power grows. Though designed to

give consistent operation, the automatic transfer

switch must be periodically maintained to

ensure proper operation and system reliability.

Maintenance of the entire system is called for in

the National Electrical Code Article 700-4, NEMA

Standard ICS2-447 and in NFPA 99.
