Well using the P=IV formula you have I = 200W/12V = 16.6 Amps. I bet it'll pop the 10 amp fuse too. I think my KC day lighters have a 20A fuse, but I'm not sure. According to this, 20A is a good rule of thumb for 16gauge wire Wire Capacity Chart I'd still be cautious with that thin of wire. Is there a reason you ran 16 gauge instead of 14 or 12?
Good call. Wasn't sure where to find reliable numbers for braided wire capacities :wavey: which raises the question, why isn't OP using #10-12 wire? I tend to go over kill on my projects, but that's just me.Do not use that chart on this link for wire capacities. It is misinformation and you will melt your wiring/start a fire.
A good rule is as follows:
#10AWG = 30amps
#12AWG = 20amps
#14AWG = 15 amps
Exactly !!It's the same for house wiring. Amps are amps. Regards.
Still have to be careful and do simple OHMS LAW calculations. Even some of the pre wired relay harnesses coming out of China are over-fused.If they are 100 watt lights, he won't have to worry about any of this by simply buying and installing a pre-wired driving light wiring harness. That makes it easy and provides the right gauge wiring, fuse, switch, and relay... ready to connect, they're made to be installable without any electrical knowledge needed.
Not exactly. Slightly smaller gauges are permissible in 12 volt DC automotive wiring due to the fact that the length of the run makes a significant difference. If in doubt, it is always better to err on the conservative side of course.It's the same for house wiring. Amps are amps. Regards.

You're referring to the skin effect or surface effect which is not in effect with DC power as the OP's lights use. The skin effect is only something that happens with RF (AC), not DC at all, with the higher the frequency the greater the skin effect. Skin effect - Wikipedia, the free encyclopediaSince electron run along the surface of the conductor instead of through it,.
