Is GFP required on a 2500A 120/208V service main?

Unless there is another section I am missing, no, but others more knowledgeable then me will soon chime in.
All I have to copy and paste from is the 2008 NEC but here is 230.95.

Ground-Fault Protection of Equipment.


230.95 Groundfault protection of equipment shall be provided for solidly

grounded wye electric services of more than 150 volts to

ground but not exceeding 600 volts phase-to-phase for each

service disconnect rated 1000 amperes or more. The

grounded conductor for the solidly grounded wye system

shall be connected directly to ground through a grounding

electrode system, as specified in 250.50, without inserting

any resistor or impedance device.

The rating of the service disconnect shall be considered

to be the rating of the largest fuse that can be installed or

the highest continuous current trip setting for which the

actual overcurrent device installed in a circuit breaker is

rated or can be adjusted.


Bold type by me.
