TABLE 7-2 SINGLE PHASE INDUCTION MOTOR STARTING REQUIREMENTS.
CODE
Volts = 230 HP = 1/4 using table 8-2; code M = 11.2 KVA / HP
11.2 x 1/4 x 1000
Therefor, starting the motor requires 12.2 Amperes.
EXAM PLE 3:
Calculate the starting amperage required for a 230 V, 1/4 HP motor start code of M
KVA / HP x HP X 1000
VOLTS
= STARTING AMPERAGE.
VOLTS
= 12.2 A.

1.- MOTOR RATING LABEL.
2.- MOTOR START CODE.
Determ ine power required to start motor using
Table 7-2. Determine starting amperage requiered
as shown in Figure 7-4.
3.- RUNNING AMPERAGE REQUIREMENT.
If code is not present, multiply running requirements
by six . Generator amperage output must be at
