Transformer - 480V 1KA

[Kilowatt76]

Hi,

I have a single phase primary, 480V 1KVA transformer and three phase secondary 240V/120V. My question is, does code require me to fuse the secondary side of the transfomer? I have sized the fuse protection for each device that is connected on the secondary side. I have a 120V cooling fan, 1A - 120V receptacle, 2A and 240V control power for a servo drive, 4A. Do I need additional protection in front of these fuses on the secondary side of the transformer?
:?

Thanks,
Kilowatt76

Take a look at the transformer again. If it is a single phase primary, it is a single phase secondary. Perhaps the transformer is two wire 480V primary, and a three wire 120/240 secondary.

I'm glad you noticed that.
I thought I was fixing to learn something new.

Oh thanks! Sorry it is a single phase 120V/240V on the secondary.
