You Ask. We Help. Your FAQs on the 45 kVA GPU

What plug comes on these units for the input cable?
We do not install AC input plugs on the input cable. Every hangar is wired differently with multiple plug choices and options that could have been installed in your hangar when it was built. You will need to consult your electrician to determine the plug needed for your unit and install it on the input cable. This is standard practice on all ground power units. The AC output cable to your aircraft includes the standard aircraft connector.

What is the warranty?
All units come standard with a 1 year warranty. You may consult your invoice or quote for upgraded warranty options and lengths. JBT has technicians based at almost every major airport throughout the United States. If you should ever have a problem with your unit and need a technician, there is a chance there could be a technician close by to your home airport.

I am going to move to a new hangar with a different input voltage, will it work in my new hangar?
These units are designed and engineered with a multi-tap transformer for your input voltage. You can easily re-wire the inside of your unit if you ever to need to change voltages from 208V up to 480V 3 phase 60 HZ or 50 HZ. You can review your manual for detail instructions on how to easily change your input voltage. If you have any questions, we would be glad to help or put you in contact with a JBT engineer.

What is the recommended circuit breakers to install for the units?
On 480V 3 Phase 60 HZ, the typical circuit breaker would be a 70 amp.
For 240V input, the unit is rated for 100 amp with a recommended breaker of 125 amps.
For 208V input, the unit is rated for 115 amp with a circuit breaker of 150 amps.

What kind of wheels do these units have?
These units now come standard with solid rubber tires.

Does this unit have a cable rack and handle to move the unit? 
The engineers at JBT designed the unit to have a cable rack on one side of the unit. The cable rack can also be used as a handle to easily move the unit in your hangar.

Can I have PDF manual for my records?
After you purchase a unit, we will send you a PDF manual along with support contacts at JBT if you should ever need them. You will also receive a manual inside of the unit when it is delivered.

Can I get a combo AC/DC unit?
You sure can! You can view our 45 kVA and 28V DC dual output aircraft ground power units.
