    Hi cupcake.

    These are a "standard" Combiner Fuse:

    http://www.solar-electric.com/installation-parts-and-equipment/midnite/cipr1/stfubr1/mnatm.html

    They fit the MidNite Combiner Fuse Holder, and, quite possibly others.
    FWIW, Vic

    Would be very surprised if any Big Box retailer would carry them.

    It is possible that some Wholesale Electrical supply house MIGHT stock them.

    AND, if you are ordering them on-line, be careful that you get a Cartridge fuse -- there are some Auto-type Blade fuses under the "ATM" banner. Sometimes the ATM Cartridge fuse is referred as ' ATM1 '.

    N AZ Wind & Sun fills orders rapidly, often with same-day shipping ... they may even be able to do US Mail (if your desert location is in the USA).

    Good Luck, Vic
