Hey everybody! I'm looking to set up my power distribution block but I'm not sure where to put it. Also, I'm not sure what gauge wire to run for power to the block from the battery and which gauge ground to run. Any thoughts or ideas?

 

Take the total Watts divide by Volts = Amps then choose a wire with the amp rating you need, or go a size bigger for some insurance. The power and ground wire will need to be the same gauge.

 

Thanks, I'm running the kc 130watt long range, kc 100watt fogs and throwing a cb in soon. I don't know the wattage though.

 

So it came up to 19.16 amps and this chart I found says use 12 gauge wire. Then another site said to use 8 gauge on their chart. 12 seems small. Would it be ok to run an 8 gauge and put a separate fuse on everything? I plan on adding more accessories in the future

 

12 awg is good for 20 amps. So that would cover your 19-16 amp calculated load. However, that would not apply to future expansion. Another thing that must be considered is the rated load capacity of the distribution block. You can simply wire the distribution block for it's max rateing. Then make sure that you do not go over that rateing when attaching the loads.

What are the specs on the distribution block?

What all do you plan on running? Are you running through relays?
