I have a step-up transformer (115V->230V) rated for 100VA that I use for
powering various low wattage European appliances. I've had a visitor from
Europe use it and overload it. It heated-up quite nicely, but fortunately
seems to be undamaged. I'd like to put an inline fuse on the input (i.e.
115V) side to prevent inadvertant overloads by people who don't understand
what "you can use it for your hair curler but not for your hairdrier" means.
Does anyone know of a modular unit that has a standard US plug on one side,
socket on the other and a modular fuse? Hmm, sounds like I'm trying to
build a UK-style plug!
Since you want to protect the transformer, I suggest putting in a box
ahead of the transformer and put in an appropriate breaker in place.
Of course I have to ask; why don't you just use the standard 220V
already available rather than use a step-up transformer?
Daniel Woodhead makes a 15 amp,125 volt plug with a fuse holder in it.
Model number 14F47 is yellow and Model number 85125 is hospital grade
transparent. You can see them here:
You will need to go to an electrical supply house to purchase one. It may
not be a stock item for some of the smaller supply houses.
I don't think they are the only ones but it may be due to the use of ring
distribution circuits rather than radial. With no fuse in the plug, the
first fuse outside the equipment would be 30A or some 7.5kW.
