GFCI protection of equipment

Does 240.13, if the exceptions are not met, exclude the use of a fusible disconnect on a 480/277 volt service more than 1000 amps? If not, how would you apply it?

You would have to get a fusible switch with shunt trip ability and GFP protection to trip it.

Many of our customers have that set up.
