How to tell 100% sure if corroded inline fuse (toyota aftermarket foglamps) is 14- or 16-awg? wirestripper seems imprecise way to measure!

FLowWOOLF NATURALS, It is hard to tell what gauge the wires are, yep, wire strippers are not a good means for sure. I usually have a small piece of different gauge wire handy like these sizes and I just compare my known sizes to the size am working with. 14 gauge is fairly big but good to use if you have incandescent fog lights, these usually pull a lot of amps, if LED's don't worry using 16 gauge., just make sure you have the positive/negative leads correct. Anyway you can't go wrong using a little heavier gauge wire on most everything you're wiring. I've had very good luck using these fuse holders and the caps keep the dampness out. I have them on my lawn mowers, ATV, car, van and on my DC emergency lights in the house and garage 0¿0 AND, you can solder the leads and insulate them with heat shrink !! Better to have a blown fuse than burnt equipment or house 0¿0 So, just cut out the old fuse and wire in one of these new ones.

Does this ship with the fuse as pictured?

I don't recall having to purchase a fuse for it so it must have come with it.

will this holder support a 20 amp fuse ?

Ten gauge wire will support up to 30 amps, so a 20 amp fuse should be fine. In theory, the fuse should be the weakest link in the chain.

What is the size of the wire with the fuse? I need at least a 12 awg wire for it to fit in my circuit.

Wire is pretty thick. I don't have it in front of me but I am an apprentice electrician and it appeared to be, from lasting impression, 10 gauge. Maybe only 12 gauge. But, I remember being happy that it was larger than 14gauge. I didn't test the water tightness, and it comes as one continuous 12"-18" loop so you'll have to cut it with this I mind

No mounting tab on this model, great product for a great price.

IP67 waterproof, pretty solid inline fuse holder. I bought it for a relay/aux led lights set up for a Suzuki Boulevard M50 motorcycle. I ordered quickly without realizing it does not have a mounting tab. My fault for not paying attention. I had to mount it with aftermarket stuff as I don't want it sliding or bumping around under the seat in an already element and vibration high setting. It works great, the 10 pack was very affordable. Around the same price for 10 as a single unit in a parts store. If you require or want a mounting tab order a different model. It fits with room to spare, is rated to safely cover the voltage needed for led lights, and they do manufacture a model with a metal tab for mounting. would recommend.

This is the one!

This inline fuse holder is exactly what I was looking for. The materials feel durable, the connections are solid, and it seals up tightly to keep moisture and dirt out. Installation was quick and straightforward, and it gives me confidence that my wiring is well protected. Sometimes it's the small components that make the biggest difference, and this one definitely delivers. I'd buy it again without hesitation.

Good Fuse Holders

Good little fuse holders. I do lots of DIY electronics projects. And for safety sake, I always put fuses in my circuits. This 10 pack of ATC / ATO fuse holders make it very simple to add a fuse. The wire size is marked as 14AWG. The holder itself is pretty standard. Fuses snap in with no problem and make good contact. The cap locks on nice and tight. All in all, these are very good fuse holders.
