Hello everyone,
I will be installing about 2000 ft of power track system in 4 rows of 500 ft long (manufactured by Vahle Mobile Electrification a German Company) 80 ft above floor powering sliding doors for the Aircraft hanger.
This track is rated at 100A, 600V, 3 phase, 3 wire w/GRD. Cat. No. KBHS 4/100-4. last number 4 means 4 meter long track section.
There will be (2) Two collectors per door installed in the power track sliding with the door, which second one used for redundancy and collector s1 and 2 cables connected to gather as one circuit.
Each collector is rated at 40A, 600V with 10 gauge or equal metric SO style cord (5 meter long), which within 8 to 10 ft goes into J box then conduit down to bottom of doors where motors/VFDs / controls are located.
Each door has two 5 HP, 480V, 3 ph motors, one on each end of sliding doors ( Total 8 doors. 4 on West side and 4 on the East side of bldg.).
There will be 16 total VFD's and controls.
Here is my questions that I like to get feed back from you guys.
1) Since track is rated 100A and collectors rated 40A each;
a) Is there a need for conductor over load protection means 75 to 80 ft up near top of doors? If the answer is yes then that will not be readily accessible.
b) Does 10 ft / 25 ft tap rule pretends to power track and collector? 100A bus is changing to 40A cable.
c) Is there any issue regarding parallel conductors since we use (2) collectors per circuit?
2) Building is a Aircraft Hanger. Does low voltage wiring (24V) needs to be in the raceway? All wiring will be above 18-to-24 inches AFF.
Thank you in advance for your reply.
