Power can be measured in watts which can be determined by Amps X Volts. We indicate the full load amps (FLA) in our catalog for power calculations. I suggest you call Grainger's Technical Product Support team and we can answer any more power questions that you may have. 800 472 4643

Answer: 
You just need the 115 volt wire & neutral. The split phase motor will have brown leads for a capacitor. The mfd rating of the capacitor will be on the motor. Also, be sure to get a motor with roughly the same rpm. Good luck.

Answer: 
We would require more information in order to find a functional replacement motor for you. Is your motor belt or direct drive? How does the motor mount to the blower housing? How many speeds does the motor have? A model number from the motor could also be helpful. You may want to consider speaking to one of our HVAC tech support agents at 800-472-4643.

Answer: 
Grainger has contacted the product supplier and has been advised by them of the following.

That blower and parts are no longer available. We can offer a replacement blower. 1TDR7 may be the best option. I would recommend calling our HVAC tech team to confirm blower dimensions and specs. 800-472-4643.
