Why cannot we put Chiller and Fire electric pumps on same ACB? 2

Hello!!

My senior engineer asked me that, Why cannot we put Chiller and Fire electric pumps in same ACB?

Can we connect both on the same ACB or not. If No, then why cannot we. Please advise on this.

What if your chiller motor catches on fire and trips the ACB?

I find it a little funny that this question is for a project in Dubai with its reputation for building fires.

hahaa!! first of all @hamburgerhelper, it is not a project. It was just a question asked by senior. And I agree with @jraef but there must be some other reason as well, which would relate this to the "Art695" fire system electrical wiring codes...
Or may be something else!

Sounds like a code-specific question for Dubai, but fire pumps are generally provided with minimal protection to give the pump the greatest chance of operating under fire conditions.

This is what I was expecting and being confused between.. thank you @ScottyUK

In addition to that "run to destruction" aspect, you also use a dedicated circuit for the fire pump so that nothing else takes it off line. That's what my comment was referring to.
