Is there a code or standard that specifies floor clearance in front of a fire pump controller cabinet?
I am installing a fire pump in an existing building which has a controller with a transfer switch. Of course the fire pump room size presents clearance issues.
I have clearances I need for sprinkler pipe, but I do not know the working clearances required in front of the cabinets.
I do have door swing clearance, but was wondering about a working clearance. Thanks in advance.

The clearance distance needs to be compliant with the NEC (NFPA 70).

Clearance issues come up a lot for us. In your case, I'd recommend you look to NFPA 70. The driver will be the voltage in the controller.

Installing new or repairing/replacing an existing module? If its just a repair or preplace what you have it what you have.

You would need to follow NFPA 70E or the NEC Section 110.26(A) for work space. There is also the Condition the cabinet is placed in relation to other utilities in the room based on Voltage.

NEC 110.26(A)(1) Working Spaces indicates a Nominal Voltage to ground chart. Follow the chart to determine which condition you have to determine if you need the minimum of 3 feet up to a maximum of 5 feet. More than likely the 3 feet is sufficient but you need controller information to verify. Supplemental information from NEC is below.
