Chiller Power Issue

Trane chiller human interface lost power. I show how to trace the power using a voltmeter until I find a blown fuse.

And now we need to find out why there needs to be a box of fuses and what is cousing the fuse to blow. Thats the video i want to see.

Bad practice, if one phase has blown you should always replace other two phases as they will have been put under load. This could explain why fuses keep tripping. 😊

not sure if you noticed... the blown fuse was on a 120v while the other 2 are on 208. it's not part of the phase but post transformer and they used a triple fuse block instead of a double + single
