Johnathon,

Just stick a 15A fuse on the whole assembly. If you put a 6 1/4 or 7A fuse
on an NST It will blow instantly. This is because with most transformers,
motors, variacs, etc. There is a power on surge or perhaps up to 40A which
will blow your fuse. Im not sure what fuses you have in the stated, but try
to get one between 12 and 15A.

Regards,
Jason
