Value in bracket is for the standard IEC motor size. Value outside
bracket is for the motor size according to NEMA standards.
2
Used for pumps where the pump shaft input power exceeds 200
hp (150 kW) and is not regulated under the DOE pump rule.
3
Special cases with power sizes above 200 hp (150 kW) which are
still regulated under the DOE pump rule. For example: Pump has a
P2 value of 198 hp (147.6 kW) in its duty point (in DOE scope) but
customer wants the 215 hp (160 kW) motor instead of the 200 hp
(150 kW). The pump is in scope of the DOE regulation and requires
a PEI value and a motor code.
