lights on rack

Hey everyone, I need some help please. I have 4-100 watt lights to
put on my rack. I need to know what size wire to use what size relays
and how many to keep my x from melting? thanks allot!

Try a search here. I posted a table with wattage vs wire gauge about a year ago.

thanks for the reply but I checked and couldn't find the comparison chart

Methinks, you need to learn to use a search engine better. ;)

I typed "wire" into the search window found at the bottom of /xterra/ and it came up. A search using the "main" engine at www.automotiveforums for "wire" and user name "Schludwiller" would have gotten a more narrow result.

Regardless here it is:

DjHornsby,

I have 4 100 watt aircraft landing lights on my xterra and I used 12 gauge wire. I have had them on the xterra for quite a while and have had no problems. FYI...the equation for figuring out total amps from your lights is watts/volts. (IE: Amps = watts / volts) Just make sure you don't exceed your alternators output because then you will have problems. My 4 lights run at 33.3 amps total when they are all on. I have a relay with 2 fuses that are 20 amps a piece and have never blown the fuses. I have more lights than just the 4 100 watt lights. They all work great and no problems at all with any of them. Good luck!
