Sometimes you need to add an additional circuit for an accessory or to simply add an extra 12v plug inside your trailer.

Here is an easy, and safe, way to add that circuit without interfering with the original circuit...

Adding additional Circuits can be a relatively simple process if you use a  "Fuse Tap". The Fuse Tap is an ingenious device that lets you add a second circuit to an existing fused circuit.

If you have the "Plastic Type" fuses with two protruding prongs coming out of the base you simply pull an existing fuse and install the "Fuse Tap" in it's place, then, you re-install the fuse for the existing circuit and install another fuse (of the appropriate amperage) for the added circuit. This gives you two "Fused" circuits where only one existed before.

There are two common sizes for the "Plastic Type" fuses, ATO and ATM, the ATO is the "Standard" size and the ATM is the Mini version. If you are unsure of the size you need you can pull a fuse and go to the auto parts store and compare your fuse to the ones on display. You can then order the appropriately sized "Fuse Tap" using the links below, by-the-way, these are the best pricing available.

If you take a look at the pictures in the links I've included (below) you can see how easy these are to install (it's almost like Plug-N-Play)

First the ATO:

Next the ATM:

Happy Scamping !!!

Please note, in reality, you will need to verify proper orientation of the Fuse Tap when installing. Install the fuse for the added circuit first, then verify continuity, next install the fuse for the original circuit (if you don't have continuity, simply turn the Fuse Tap around). The description used above was simplified for illustrative purposes.

PS: Fuse Taps are also available for "Glass" type fuses.
