Generator fire pump

[hhsting]

I have fire pump 4 pole ats controller breaker all in one at opposite side of main electrical room fed from normal side utility service and emergency side fed from generator which is separetley derived has ground rods as electrode.

Generator is about 40 feet from the main electrical room where their is building ground electrode system.

The fire pump Ats controller breaker all in one needs to be grounded with common ground electrode and has main bonding jumper.

How would this work with the generator side if 4 pole Ats controller breaker fire pump has ground normal side with main bonding jumper?

Ok no takers. Basicaly would 4 pole be ok or need to switch to 3 poles Ats controller breaker for fire pump?

From normal side you have grounded conductor incoming to bar #1 inside 4 pole ATS. In the ATS their is main bonding jumper normal side.

Now the emergency side would have bar #2 or same bar #1 into which equipment grounding conductor plug into? How does one wire 4 pole ATS emergency side and normal side?

Ok. So for service rated fire pump ats controller normal and emergency side can be wired either as 4 pole or 3 pole and generator can be separately derived or non separately derived depending on poles of ATS either way their should be no problem.
