Video Transcript for Review of Spectro Wiring - 14 Gauge ATO-ATC Fuse Holder - SWC9538

Jeff: Hello everybody, this is Jeff at Today, we're going to take a look at the Spectro 14-Gauge In-Line ATO-ATC Fuse Holder, for a quantity of one. Now this is an in-line fuse holder that's used for applications where over current protection is required. This type of fuse is normally used in low voltage in motor vehicles. Now the wire gauge on this holder is 14 gauge size wire. So it is designed to accept either a 10 amp or 15 amp ATO or ATC style fuse.

Now to go to install this holder, what you'll want to do, you can see it's a single loop design. You just cut it where you need to, and then you connect the two ends after you cut it to the wiring in line. And then you'll install your fuse for protection. So basically when you go to install your fuse, if you notice there's your two holes there, I happen to pull .. Here's that type of fuse and it has ...

This as a 10 amp one.So you just take the two tabs, line it up with the two spots in there, and then just push it in all the way. Make sure it goes down all the way to give you the protection. Put the cap over there, and then that will protect the fuse from any damage or from the elements. Now this is for a quantity of one fuse holder. Now the fuse that I just demonstrated with that is not included.

You would have to purchase the fuse separately. But that should do it for the review on this Spectro 14-Gauge In-Line ATO-ATC Fuse Holder..

  • What is Wattage Rating for Spectro 14-Gauge ATO-ATC Fuse Holder
    Since the Spectro # SWC9538 is rated for up to a 15 amp fuse that means it can handle up to a 180 watts since wattage is volts (12) multiplied by amps.

  • Can I Hard Wire the Jensen JTV19DC Diretly to the Power Source
    The Jensen LED RV TV with DVD Player part # JTV1917DVDC can be hard wired if you choose not to use the plug end. When doing this however you will be eliminating the fuse holder in the plug. With that said you need to add an in line fuse like the Spectro 14-Gauge ATO-ATC Fuse Holder part # SWC9538. With out this in place we can't recommend hard wiring.

  • Where to Find Fuse for Power Steps on Motorhome
    The fuse for power steps on a motorhome, like part # LC3658373, will be found on the 12V power wire that runs to your battery bank as opposed to a fuse in the power center like what you find on a vehicle. What you're looking for is a fuse holder similar to the part # SWC9538 where you can remove a cap to get at the fuse. Attached is a sample wiring diagram for you to check out. Please note that different steps have different wiring configurations so the location of this fuse can vary...

  • What Size Fuse to Use With the Vision X H4 Halogen Headlight Bulbs with Relay Harness # VX-HH4-R
    The Vision X H4 Halogen Headlight Bulbs with Relay Harness # VX-HH4-R has a max draw of 8.3 amps. Because of this I recommend going with a 10 amp fuse. You can use the Spectro 14-Gauge ATO-ATC Fuse Holder # SWC9538 to install the fuse that you can purchase at your local hardware store.

  • Troubleshooting Power Connection to Jensen RV Stereo JMW60A
    The Jensen RV stereo # JWM60A that you referenced has a multi-pin connector for the various power and speaker connections. In the instructions, which I linked for you, the wiring diagram shows +12V power should connect to the RED wire for pin 15; the ground should connect to the BLACK wire for pin 16. The BLUE remote trigger wire connects to pin 14. This requires a 100mA signal from another device to turn the unit on. I attached a shot from the manual showing all of these pin assignments...

  • How to Wire Solera Smart Arm 12V Power RV Awning
    To get power to the controller of your Solera Smart Arm 12V Power RV Awning part # LC759404, you need to tap into an existing circuit, or run a power wire from the battery with an inline fuse holder, and a 15 amp fuse, like part # SWC9538, and part # C58450-1. The red "POWER" wire on the motor or awning head, attaches to the red power wire on the controller. The black wire is ground. The "EXT IN" and "RET IN" wires will route to inside where you have the switch mounted. The controller...

  • Adapter Needed for External Battery to Trailer Side 4-Way
    We do not have a direct adapter, but you could very make your own. Using alligator clips and the Hopkins Wiring Harness # HM48035 would allow you to do this. I do recommend installing at least a 15 amp fuse # C58450-1 and Fuse Holder # SWC9538 between the 4-Way and the battery to keep your setup safe in case of a short.

  • Is it Possible to Need a Larger Gauge Wire with the Solera 12V Electric RV Awning Conversion Kit
    When installing the Solera 12V Electric RV Awning Conversion Kit # LC434724 you will need to use 14 AWG or larger as necessary to provide 12V minimum at all times at the connection to the LCI-supplied power cable. Since you are running a longer distance, you will want to use the larger 12 gauge wiring like the 12 Gauge # 12-1-1.

  • Troubleshooting An Ultra-Fab Electric Trailer Jack That Just Keeps Blinking
    Typically if an Ultra-Fab electric trailer jack is just blinking it indicates that the power source isn't enough to fully operate. Have you checked the voltage running to the to jack with a multimeter # PT89ZR to ensure it's getting a full 12 volts? A fuse is going to blow to protect the jack's circuit board but doesn't always come included. You could use an inline fuse holder # SWC9538 to properly protect your jack. You will need to look at the amperage pull to determine the correct...

  • Can MaxxFan Deluxe Roof Vent # MA00-07500K be Wired Directly to Battery
    There is no reason why you cannot power your MaxxFan Deluxe Roof Vent # MA00-07500K from your battery using a 12-Volt DC Outlet # HM55115. You will then just need a plug for the socket, rated properly for your power application. You may want to install a 10 amp fuse with a Fuse Holder # SWC9538 as well to help protect the circuit.

  • How To Wire In Three Thermat Heat RV Tank And Pipe Heater Pads
    The ThermaHeat RV Dump Valve Pipe and Elbow Heating Pad # 277-000162 pulls 0.3 amps and the ThermaHeat RV Holding Tank or Step Heater Pad # 277-000164 pulls 4.8 amps. Assuming that you're having them all run off the same switch and wiring you would be fine using a 10amp fuse # SWC9538 and some 14 gauge wire. You can run the power wire from the battery to a switch, like part # DG52452VP, and then either splice three separate wires from the switch to the pads or one wire from the switch...

  • How to Connect Fuse to ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat
    The ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164 has a 4.8 amp rating. If you can find a fuse rated for 5 amps that would be ideal but aside from that we have the fuse holder # SWC9538 which is compatible with 10 amp or 15 amp # C58450-1 fuses and you will simply splice one end of this holder to the power wire of the heater pad and then the other to your power source. If you'd like the ability to control power to the heater pad then I also recommend installing...

  • Powering Interior Trailer Lights With Generator
    You may splice your generator into the main 12V power and ground from the trailer's 7 pin connector to power the interior lights if you use an inline fuse like part # SWC9538 and fuse part # C58450-1 between the 7-pin 12V wiring and the generator 12V outlet. I recommend to wire in the power and ground to the Optronics 12V DC power plug part # A-200 to plug into the generator. The Optronics plug is rated for 12 amps. You want to use an inline fuse because if the wiring shorts out it can...

  • Troubleshooting Trailer Lights That Are Getting Too Hot And Failing
    It sounds like your lights are drawing too much power and it is an issue inside the light. You can use a multi-meter like # PT89ZR to see what voltage and amperage are being drawn. One way to solve this is to put an inline fuse like # SWC9538 and Curt 15-Amp Blade Fuse - Quantity 1 # C58450-1. Another option is to use an In-Line Circuit Breaker - 20 Amp - Perpendicular Mount Bracket # 9506P.

  • Wiring the Rocker Switch on the Solera Smart Arm
    According to the wiring diagram, the optional manual awning rocker switch on your Soldra # LC759404 Smart Arm has a red wire that runs to a 15A fuse and then to the positive post on your battery. The Smart Arm Control also has a red wire that runs to a 15A fulse and then to the battery. An inline fuse would work in this case. Use the Spectro # SWC9538 inline fuse holder along with a Curt # 58450-1 fuse rated for 15A. You could potentially run wires to your power panel if you have...

  • What Is Needed To Swap From A 120v Fridge To A 12v Fridge In An RV
    You won't be able to use the 120v outlet that you already have for your Dometic refrigerator and will have to run new lines to your DC distribution panel or directly to the battery. The Furrion Arctic RV Refrigerator with Freezer # FR42SR has easy hook ups on the back of the unit where you can push the wires into the corresponding terminals and tighten down the screws to secure them. I recommend running some # 10-2-1 from the unit to your DC panel to the unit for the positive and negative...

  • Replacement 15A inline fuse for Tekonsha trailer wiring harness
    The ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT comes with the inline fuse that you are referring to. If you don't have it, then you can go with Spectro 14-Gauge ATO-ATC Fuse Holder # SWC9538 along with the compatible Curt 15-Amp Blade Fuse # C58450-1. For the butt connector, # DW05714 would work well; this is sold in a quantity of 1. If you want shrink wrap butt connectors, then you will need to purchase a pack of 10 #...

  • Troubleshooting A MaxxAir MaxxFan Deluxe That Isn't Responding To Temperature Settings
    If your MaxxFan Deluxe Roof Vent w/ 12V Fan and Thermostat # MA00-06200K isn't properly responding to commands then the first thing to check is your power and ground. Make sure that you have a secure ground connection and check the voltage with a multimeter # PT89ZR to ensure the unit is getting a full 12 volts to properly operate. If the power and ground are both fine then it's most likely the circuit board malfunctioning and would need to be replaced with part # MA10A21276K. I would also...
