DESCRIPTION OF REQUEST:
The motor of DP-1 is not capable of operating with the wye-delta soft
start feature specified in SS 16900 2..03 1411.
A wye-delta motor is required to achieve the performance desired.

RESPONSE:
Provide motor capable of operating with specified Wye -Delta motor starter. This motor does not have
to be explosion proof as specified, a non -explosion proof TEFC motor similar to attached motor in
stock in Anchorage quoted by Hayden Electric Motors will be acceptable. Note this quote is for a US
Motor 250T frame motor as a direct replacement for the 254T frame motor currently installed on the
pump. It is the Contractors responsibility to coordinate new motor application with pump
manufacturer.
Submittal for DP-1 did not contain sufficient detail for determining if motor was suitable for application
of the Wye -Delta motor starter. Submittal only indicted that a 208v/3ph 254T frame motor would be
provided. Submittal approval stipulated it is the "Contractors responsibility for coordination with all
other trades and the satisfactory performance of work". Spec Section 01300 ¶ 1.05 J. requires the
Contractor to review and coordinate each submittal with other submittals, requirements of the work, and
the Contract Documents. Spec Section 00700 ¶ 3.4.1, 6.12, 6.13.2 and 6.21.2 has similar wording for
the Intent of the Contract Documents and Contractors Responsibilities.
We are asking the Contractor to fully investigate the implementations of this recent discovery, in light
of above information, and then the AUTHORITY can enter into negotiation with the Contractor for any
allowable Change.

GLEN:
I have a US Electric Motor 15 Hp 12 lead motor on the shelf (model AE52) for $948.54. This
motor in not explosion proof but it will operate at 208 VAC with a wye-delta starter. I was unable
to locate a 12 lead explosion proof motor. Let me know if this will work for your application.
Thank you,
Roger L. Saunders

FULL VOLTAGE ACROSS THE LINE START AND
RUN ON A CONNECTIONS. ALSO SUITABLE FOR
START ON Y, RUN ON A.
Per NEMA MG1 1998-1.76, "A Wye Start, Delta Run motor is one arranged
for starting by connecting to the supply with the primary winding initially
connected in wye, then reconnected in delta for running condition." This is
accomplished by a special Wye -Delta starter configuration using six leads
from the motor and is intended to limit the inrush current required to start the
motor.
Motors designed by US Motors for Wye start, Delta Run may also be used
for across the line starting using only the Delta connection. Damage will
occur if the motor is operated with load for more than 30 seconds on the Wye
without transition to Delta.
To reverse direction of rotation, interchange leads L1 & L2.
Each lead may have one or more cables comprising that lead. In such case,
each cable will be marked with the appropriate lead number.

Davc on Saturday Bryan called fxorn Unalakleet and advised tliat the fuel distribution.
pump DP-1 only has nine leads.
To properly connect the wye-delta starter to this motor we require twelve leads. We have
to be able to break apart the center connection of 10 — 11 — 12.
