Roof Pump - Please tell me what I have wrong

I cut some off my light bar lol

One last question just to make sure im right.

one side says bat and the other says aux. So i hook up my red positive wire comicoming from battery to the “bat” bolt and then hook up another red positive wire to “aux” going to pump and that fuse is done? Its fine to use on my 17 amp North star or should i hook up the 25 amp inline fuse to it?

Yes, I believe so. Then just run your negative straight back to the battery.

Thats what i figured just wanted to make sure so i know if i should run separate fuses to each pump.

It comes down to wire size. The size of the wire depends on how many amps your equipment is. The fuse/breaker is dependent on the size of wire.

:sweat_smile: well thanks i learn something new everyday on here

I think I follow what you’re trying to say, but it’s coming across a little backwards. Your first consideration is the power draw of the appliance you’re running. That determines what size wire to run, and then what size fuse/breaker to use.

Also, the size wire == size breaker is more relevant in a residential setting, where you may be running several appliances on the same circuit with varying loads, and you don’t want the cumulative load to surpass the safe limits of the gauge wire on that circuit.

When you’re dealing with a single appliance circuit, the relationship between appliance power requirements and breaker selection is more direct.

I thought that’s what I was saying but you definitely cleared up any confusion. It might’ve helped if I started a second paragraph after the first sentence. The “It comes down to wire size” was commenting on his question to whether he should hook up his North Star pump to the same breaker.

Thanks Alex

Ok, gotcha. I misunderstood.

@Grizz, it should go without saying, but if you’re putting two pumps on the same fuse/breaker, don’t try to run them at the same time :wink:

Its working good! Haven’t tried to north star but im sure it will run great. Trying to grill steak and fill up sh. I did realize im going to need a on off switch. Im going to mount these on the side like racer. This isnt the same one at lowes but you get the idea.

I’m glad you questioned it because you explain things much better than I’ll ever be able too. When it comes to electrical you don’t want any confusion at all. You definitely made it easier to understand. It might’ve helped if I went into more detail when I said “it depends on the wire size”. When I typed that I was just thinking that it’s fine to go with larger gauge wire then needed but you have to also go with a larger fuse/breaker. I guess that’s good to point out too. It’s fine to go with larger gauge wire than needed but not smaller. For fuses and breakers it’s fine to go smaller but not larger.
