Metering for electric fire water booster pump

[Rajun Cajun]

How have you handled this issue on any of your projects?
I have a building with a 20 HP booster pump and a 3/4 HP jockey pump, both controlled from the FM approved controller cabinet.

Depends on the utility, most common in the south, is the poco has CT’s in the utility transformer cabinet, so the fire pump is on the load side with the building service, up north, a lot of utilities have a CT cabinet remote from the transformer, and fire pump feed is pulled from there. Some older buildings, the utility CT’s are in a pull section in the main gear. The fire pump feed can also originate there, providing it’s a pull section, and does not contain the main.
