The LH battery is a walmart battery and within its free replacement period. Hartzell Engine Technologies LLC. Dont worry calculating the wire size is made easy with the wire size guides below.
Branch circuits that contain two or more motors must have wire in which the ampacity rating of the wire must be at least 125 of the full-load current of the largest motor plus the sum of full-load currents for the rest of the motors. To select a NEMA starter only horsepower and voltage are needed. The starter which is a rebuilt one from OReillys by its self is pulling 135 Amps.
This is a newly rebuilt motor from AutoZone. Click to see full answer. Bike is bone stock other than cosmetics.
38 rows So if you divide 1500 watts by 110 volts you end up with the maximum current the. Also what causes a starter to draw too many amps. The no-load amp draw will vary depending on the type of starter.
I understand what Ipugh is saying. NEMA starters have interchangeable heater elements and makes NEMA starters attractive in projects where the motor specification is not known until the start-up date. Jet pump style well pumps can vary in size from ½ HP to 1 ½ HP.
It was 141v dc at idle and the stator was pushing 17-20v ac. The same is true if the starter does not achieve the specified rpm. Its a bit complicated but amps increase when voltage drops.
As in most electrical situations it is important that you know the maximum amp draw of the device being installed. Couldnt come close to getting the motor to start. A good general rule-of-thumb figure is one amp starter draw for every cubic inch of motor.
If the amp draw is too high the starter needs to be replaced. If you cannot find what you are looking for or what you are looking for is not where youd expect it we encourage you to contact Hartzell Engine Technologies LLC to find the best starter for your particular application.
