What Size Fuse?

[Okiehunter]

I am mounting two 55 watt halogen work lights on my Ranger using 14 ga wire. Both lights are running to one switch.

What size fuse should I put inline?

Thanks

15 amp

Remember the fuse is to protect the wire, not the lights!

My vote is for 10A

nailed it on the head. if you want to know how much you are pulling take your watts and divide by your voltage 110 watts (55W X 2) divided by 12v gives you 9 amps so you are way good.

Well since it is a vehicle, then divide by 12 volts!

You are on the right track!

A 10 amp fuse will work but the 14 ga. wire is good up to 15 amps, roughly!

A 10 amp fuse will be fairly touchy and may pop fairly often.

If you start popping 15 amp fuses then there is some other problem.

Make sure you get a good ground connection to either the battery or the frame of the buggy!

Would that be 110/12v = 9.17 amps? Or am I missing the math somewhere?

We posted at the same time!

yea i caught that after i posted so i went back and corrected it.

[Okiehunter]

Got it, thanks. I grounded direct to a buss comming off the battery. I ran out of wire connectors and did not get a fuse cause I was not sure what size. I will wrap up tommorow and see what happens. It is a major pain pushing wire through roll-bar but I got it done.

How did you get wires through roll bar? Did you have to drill hole somewhere and fish it through? I have been wanting to do this but am not wanting drill hole.

[Okiehunter]

Yes I drilled one hole in the top and one at the bottom. The cross wire did not require holes. The top hole will be covered by the top. I used rubber grammets to fill the hole along with silcone (sp) and covered the wires with elec tape.

Just to follow up, these things are BRIGHT and they work like a charm. Thanks for the input. I may not can see where I am going but I can see where I been.
