BYPASS ISOLATION SWITCH
.1
As shown on the drawings, specified transfer switches shall be included in a factory assembly
with bypass-isolation switch equipment. The bypass-isolation switch shall provide a safe
means for manually bypassing the transfer switch from either source (Normal or Emergency)
to the load, while under load if necessary, and isolating the transfer switch from both sources
for maintenance or repair. Two source bypass is a requirement of NFPA 110. Designs which
bypass to only one source are not acceptable under this specification.
.2
By-pass isolation switch equipment shall be UL listed per Standard 1008 CSA Certified with
continuous current rating, voltage and frequency ratings, and withstand and closing ratings
equal to the transfer switch ratings at the specified conditions of ambient temperature,
humidity and altitude.
.3
Bypass switch shall be a fully rated, manually operated switch, rated for the same loads as
the automatic transfer switch.
.4
Positive mechanical interlocks shall prevent all possible source to source connections.
Designs depending on electrical interlocks to prevent source to source connections, or which
intentionally interconnect the sources are not acceptable.
.5
Isolating contacts in the draw out isolation mechanism shall allow the automatic transfer
switch to be separated electrically and mechanically. The isolation mechanism shall be
interlocked so that either the transfer switch must be bypassed or the transfer switch must be
open before the mechanism shall permit transfer switch isolation.
The draw out mechanism shall provide for three-position operation; CONNECTED, TEST and
ISOLATED. These positions shall be shown on the draw out position indicator. In the CONNECTED
position isolation contacts shall be fully engaged and closed with the automatic transfer switch control
cable connected.
In the TEST position isolation contacts shall be open, with the transfer switch control cable connected.
The TEST position shall allow operational testing of the automatic transfer switch and the controls
without power disruption to the load.
In the ISOLATED position the automatic transfer switch and the control shall be completely isolated
from all power sources. In this position safety shutters shall close to cover bypass power terminals for
operator safety.
Once isolated, the automatic transfer switch shall be capable of being completely withdrawn from the
cabinet for inspection or service without disconnection of power cables.
When re-installing the transfer switch from the isolated position, the isolation mechanism shall not
permit connection of the transfer switch unless it is in the open position, and shall automatically open
the transfer switch if necessary regardless of the availability of electrical power. When the transfer
switch is fully connected and locked in place, the mechanism shall move the transfer switch from the
open position to the closed position on the same source as the bypass switch.
