Onan Generator Question

[Aussiecoach]

Hi

I remember from some other posts taht we have a few Onan guys on here, and thought maybe you could help me

I am looking at two different Onan diesel generators. They are 230V 50Hz models being in Australia and both look the same But
One is a 5HDKBB-2862C Spec C with Insulation: Nema Class H and the other is a 5HDKBB-2862B Spec B with Insulation: Nema Class F all other output figures are identical

Just wondering if anyone knows what the difference between these would be and what the Nema class is?
Is the C Spec just a later revision of the B?

Hi

Also wondering if 1000hrs is a lot for the little 2 cyl water cooled Kubota diesel engine in these?

Thanx
