i blew the 15A fuse right away, first time turning on, replaced them with a spare 20A fuse from my panel, is it safe to use a fuse rated higher than initially needed...?

 

Not gonna hurt if it is that close only 5 off I wouldn't use a 30 on a 5 though

 

The fuse is there for a reason and its capacity was not randomly chosen. It has been sized for the wire gauge and wire runs that it protects. If the original fuse blows with the increased load, do not upsize the fuse. If I had this problem, I would use a relay to bring in power from another fused source instead.

 

HIGHLY recommend listening to Bob on this one....well and most other Q&A posts that he replies to.
