Quick Cable Question

Im ordering my supplies to do my lights.

Is 25' of 4 ga welding cable sufficient to run as a powerline?? (Im mimicking FitchVA's setup by running power to the back and setting up my relays and such there.)

thanks

Jesse

Ive decided to run 6 gauge so that I can run a fuse, if anyone is lurking

any thoughts?? im running it to run 10 lights

Hell yea you will be fine...a bit overkill to me but hey good to be on the safe side.

Thanks bretto, I just needed some confirmation.

You'll have to add up all your lights amperage usage and then see what gage wire you are allowed to use safely.

Personally, I have 250W bulbs that I want to install. 10 of those would melt the wire rated for 10 55W bulbs.

How about some details on those 250 watt lights?!?!

They are Boeing 747 aircraft lights. Used to illuminate the wing at night for ice formation inspections at 30,000+ feet, at 500+ mph.

They go by part number Q4631 and are made by GE and Phillips. The GEs cost $70, the Phillips only $40. I've mounted mine in a $16 1/4" thick rubber housing from Nappa. ( Google the part number and see what shows up ).

The bulbs are about 4.5" in diameter and are really the same size as the $30 spot/flood lights used on fork lifts or tractor trailers. See http://cgi.ebay.com/ebaymotors/Jeep...33709QQitemZ8009449599QQrdZ1QQsspagenameZWDVW

The only draw backs is that you need a good charging system or else you can't leave them on for a long time. Also, best for when driving since they do get hot ( can't stay still for more than 10 minutes, even thou I've yet to see one blow due to overheating itself ).

As for brightness, everyone who's seen one has to pick up their jaw. My friend used to have $250 PIAAs and he says that these are still brighter.

Thanks for the wire-gauge link.

I should have known there was a formula on crutchfield. Thanks again
