Hi!

I saw a 120Vac single phase circuit which supply many drives where the neutral is fused. This neutral is grounded at the transformer end.

I think this is not ok, I'm I right?

Thanks.

 

Responding to Anonymous' 19-Jul-09 (09:36) query... if an Authority Having Jurisdiction (AJH) requires that the installation comply with the USA National Electric Code (NEC or NFPA-70). then, yes, you are right, and the fuse in the grounded conductor is not correct!
