As you are located in the US and just to confirm that you are aware of the difference between British and American fuse ratings. US fuses of a given rating (ie 30 amp) will carry much more current than a British fuse of the same rating.

" The US system rates the fuse based on the continuous load it can handle for a specified period of time w/o blowing, whilst the British system expresses the load at which the fuse will immediately blow."
