My son has a Hiwatt DR103. It has startedblowing the mains fuse periodically. He is running a 3A fuse there. We got the unit from England where it used 240v. When I look at the schematic it says 3A and then in parenthisis it shows 6A. Based on P=IxE, it would take twice the amps in the USA to give the same wattage.
Am I safe to assume I could go up to the higher amp fuse? Would it still give the same level of protection the 3A did in England?
Forgot to mention.
It should be a slow blow fuse.
Here is a link to the owner's manual.
It actually specifies a 6.3A fuse but I believe that you will do just fine with a 6A slow blow fuse which will probably be easier to find.
Note that the HT fuse valuse stays the same for 120V or 240 V operation. See the manual for more info.
