Working with a customer that is inquiring about an inverter duty explosion proof motor that wants the temp rise to be T5 instead of its given T3C rise.
First of all, this motor is 10hp, 400/50/3, 4:1 CT, Class F insl, Div I D,E,F,G, XP/XT.
It's not a problem setting the T'Stats to trip power when the windings are approaching T5(100c). My question is that, Can you put a T5 code on the nameplate that would ordinary be T3C? My understanding of this is that this is the highest the surface temp of the motor will reach before kicking off power and being under the lowest MIT of a Class I, Class II Groups that are selected.
