Transfer Switch &Circuit Breakers
An automatic transfer switch is designed for connecting a critical load between 2 dissimilar power sources (that can be up to 180 degrees out of phase) when either source is not acceptable.
A circuit breaker’s designed function is to disconnect the circuit (conductors) and the load from the power source under overcurrent conditions.

Transfer CategoriesTransfer Categories All transfers can be placed in one of two categories
Transfer between two “live” sources
test transfer
re-transfer to normal
Transfer from a “dead” source to a “live” source
occurs as a result of a source failure
how dead is dead?
These categories apply regardless of the type of switching used
Network PowerASCO

Open Transition TransferOpen Transition Transfer “Break Before Make” switching
Load is disconnected for a finite period of time
Open transition -- step by step
transfer initiated
operator energized
TS mechanism begins to move
if transfer is between two live sources, an arc is formed
if transfer is from a dead source, load is disconnected
arc extinguished (if leaving a live source)

Implications of Seismic LoadsImplications of Seismic Loads Keep in mind the IBC
(International Building Code) replaces the UBC (Uniform Building Code)1997 edition
Section 1621.1.6 of the 2003 International Building Code is clear:
Importance Factor (Ip) 1.5, Life – Safety Component is required to function after an earthquake
Network PowerASCO

Who’s Responsible?Who’s Responsible? The IBC clearly states that it is the responsibility of:
Equipment manufactures
Suppliers
Installers
Design Team Managers
To insure that their component remains “on line and functional”, after the emergency has occurred!

Benefits of Connectivity ModuleBenefits of Connectivity Module Total No. of devices per LAN will not be limited to 32.
Therefore the number of dedicated LAN’s will be reduced.
Remote monitoring of transfer switches and other devices.
Ethernet is the “de-facto” standard for local and wide area network
Computers come with Ethernet built-in. Therefore no need for Serial Card setup.
Many different types of Device/Application protocols at different serial baud rates can be brought on one Ethernet wire for example: ASCO I, II and Modbus at different baud rates, 2 wire or 4 wire devices will be connected to a single “Ethernet LAN.”
Potential savings for building owners for huge wiring costs.
Standard commercially available LAN/WAN diagnostics tools will be utilized for troubleshooting.
Ethernet LANs can be extended to miles with commercially available Ethernet repeaters and fiber cables.
