Why do you think it's the chiller?
You have to isolate each devices. On one and a time.
Once, I have a problem with my tank.
Whenever I on the lights, the house will tripped.
So think that it's the light and bring all the way to replace.
However, when there, noting happen.
Bring back, on and tripped.
Narrow one at a time and found it is my extension bar giving problem because once the light on, it need more curent and overload the extension bar...
