Not sure. Quite often the alternator actually makes the battery output about 14v. That would lower the current in the wires. HOWEVER.. When you turn on lots of lights and draw lots of power off the battery you can drop it lower. I've seen it to almost 8v with a ton running from it(guy probably needed a bigger alternator/battery combo) but that would make it at 7A and would blow your fuse. I'd almost put an 8A(do they exist?) or a 10A fuse in. 16ga can hold 21A correct? So that would be an ok fuse to put in

jkjeeper06 I'm not sure of the amp capacity of each wire(normally I just look it up) but provided you have 4 outputs out of the relay, your wires will carry 4-5.5 amps each depending on battery voltage(14-10v respectively). If you put another inline fuse on each, you could guarantee too much doesn't go thru the wiring

4 x 55W bulbs for rock lights - Wiring questing

I have 2 sets of wally world platinum burners (55W per bulb) and was going to connect them to a single relay and single switch

55W x 4/12V = 18.3A

Therefore, I am using a 12G with a 30A fuse 6 inches from the battery

This connects to a relay (Relay clip 30)

Questions : can the rest of the wires be all 16G?

From the relay clip 87, 1 set of 16G wires comes out, then the other set of 16G will be spliced into this?

Not quite sure, I did something similar 10 years ago with some neon lights and my toyota and my wires fried, thank goodness for the fuse
