PIP ELSAP20 June 2007
Low-Voltage Automatic Transfer Switch
4.2.4 If closed transition transfer is specified on the purchaser’s PIP ELSAP20D
Data Sheet, the automatic transfer switch shall have the following
characteristics:
a. Interconnection time 100 milliseconds maximum
b. Operate as open transition switch if the primary power source fails
4.2.5 If delayed transition transfer is specified on the purchaser’s PIP ELSAP20D
Data Sheet, the automatic transfer switch shall have the following
characteristics:
a. Adjustable delayed transfer time
b. Delayed transfer in both directions
4.2.6 Transfer switch shall be double throw (i.e., opens one set of contacts while
closing the other set), electrically operated, and mechanically held.
4.2.7 Electrical operator shall be a momentarily energized, single-solenoid
mechanism.
4.2.8 Transfer switch shall be mechanically interlocked to ensure only one of two
switch positions (i.e., normal and alternate).
4.2.9 Switch contacts shall always be closed on a minimum of one of the sources.
In-between positions shall not be permitted.
4.2.10 Switch shall be positively locked and unaffected by momentary power
outages.
4.2.11 Main contacts shall be silver plated.
4.2.12 Inspection of all contacts shall be possible from the front of the switch
without disassembling operating linkages and/or disconnecting power
conductors.
4.2.13 Stationary and moveable contacts shall be replaceable without removing
power conductors and/or bus bars.
4.2.14 If switched neutral conductor is specified on the purchaser’s PIP ELSAP20D
Data Sheet, the automatic transfer switch shall be provided with fully rated
overlapping neutral transfer contacts with the following characteristics:
a. Neutrals connected together only during the transfer and retransfer
operations
b. Contacts overlap 100 milliseconds maximum
4.2.15 If solidly connected neutral conductor is specified on the purchaser’s
PIP ELSAP20D Data Sheet, a neutral conductor plate with fully rated
AL-CU (aluminum-copper) pressure connectors shall be provided.
4.3 Bypass-Isolation Switch
4.3.1 A two-way bypass-isolation switch shall provide manual bypass of the load
to either source and permit isolation of the automatic transfer switch from all
source and load power conductors.
4.3.2 Bypass to load carrying source shall be accomplished with make before
break contacts so that power is not interrupted to the load.
