Video Transcript for Review of Spectro Wiring - 12 Gauge ATC-ATO Fuse Holder - SWC9539

Jeff: Hello everybody, this is Jeff at Today, we're going to take a look at the Spectro 12-Gauge Inline ATO and ATC Fuse Holder. It is for a quantity of one. Now, this is an inline fuse holder that's used for applications where over current protection is required. This type of fuse is for low voltage protection in motor vehicles.Now the wire gauge on this holder is 12-gauge size, so that'll tell you that this holder will accept either a 20 amp or 25 amp ATO-ATC style fuse. Now to install this holder, you can see it's a single loop design.

So what you'll need to do is cut it where you need to, and then connect the two ends after you cut it to your wiring inline. And then what you'll do is just install your fuse for protection. Now I did happen to pull, here's a 20 amp type fuse that'll fit in there.Here's your two connectors in there, you just line the tabs up with those connectors and then push all the way down and you'd want to push it all the way down and make sure it makes the connection. And then go ahead and put that cap on there to protect that fuse from the elements or from any damage. And then just like that, you're all ready to go.

Now, this does include one inline fuse holder. I do want to mention that this fuse that I just showed you is not included. The fuses would be sold separately.But that should do it for the review on this Spectro 12-Gauge Inline ATO-ATC Fuse Holder..

Just what I needed, sturdy


I did a lot of shopping around, and this unit was the best price I could find for the same load rating. It was easy to install and works like a charm. One small down side is, I wish the drop foot tube was longer with additional holes.
I bought two and installed one on a 18' flatbed trailer and one on a 14' dump box trailer. I'm looking forward to not having to do all that hand cranking!

After a year, Im very happy with both my units. I have not had any problems with them.
JEMS C - 08/27/2016


I hooked up shore power without removing the electric hitch plug this caused the fuse to burn out saving the battery getting a 120v charge.
Good results excellent product


Product works as expected. Staff was helpful with answers to questions. Products arrived in good condition and sooner than expected.


Quality product ( fuse holder ) received sooner than expected


Just what I needed




works great ordering was easy

  • Does The Peterson Accessory Plug and Socket Kit Come With A Fuse
    The Accessory Plug and Socket Kit - 12V # PE53QV does not come with a fuse inside of it and would need to splice in an inline fuse holder like # SWC9539 and use a 15 amp fuse to properly protect your equipment.

  • Recommended Wiring Instructions For The Rampage Radiant Backseat Heater
    The 12v cigarette lighter outlets we carry aren't going to be rated for a 25amp power draw so you would need to wire the Rampage Radiant Backseat Heater - 300 Watt - 12 Volt # RA3501 either directly to the battery with a in-line fuse holder like # SWC9539 or to the DC distribution panel in your RV's power center with a 25 amp fuse. The # RA3501 isn't really designed to be connected to a cigarette lighter style outlet but I'm assuming you're wanting this so that you can unplug and remove...

  • Installing LaSalle Step Heaters On A School/Commercial Bus

  • Parts Needed to Add Second Battery and 12V Outlets to Bed of Chevy Silverado
    To add an additional battery in your 2002 Chevy Silverado I recommend adding the Redarc Smart Start Isolator # 331-SBI12D in-line between the truck's start battery and the auxiliary battery. This will transfer power in either direction to maintain the charge on both batteries. Then to add 12V outlets to the bed you can use the Roadmaster # RM-9332 and run the wiring up to the Silverado's battery using 12 gauge wire # 12-1-1 (sold by the foot), butt connectors # 05732-2, a 12 gauge fuse...

  • How to Hardwire a 12 Volt Accessory Outlet in a Truck Bed
    Only a 7-way trailer connector will have a 12-volt power wire ran to the connector. A 4-way trailer connector will not have a constant 12-volt power wire. As long as the 12-volt power wire running to the 7-way trailer connector is rated for the amperage required for your 12-volt accessory outlet then yes, you can use this wire for powering the circuit. Depending on how the vehicle is set up, your trailer connector may or may not still have power while the vehicle is off. To test this,...

    The kit that you want to use for the Detail K2 snow plow on your 2015 Ram 1500 is part # K281488LB2, when I reached out to Buyers Products about the kit # 3371311110 they said not to use their kit for your Ram pickup.

  • Parts Needed to Flat Tow a 2015 GMC Terrain
    In order to convert the 4-way trailer connector on your 2014 Thor ACE 29.2 to a 6-way trailer connector you would want to use the Mighty Cord Trailer Connector Adapter part # A10-6034VP. The adapter plugs into the 4-way you have on your RV and will require you to hardwire in 3 additional wires. The white wire is for the ground and will need to be attached to a clean bare metal surface. The black wire will then need to be ran to the battery with an in-line fuse holder such as part # SWC9539...
