Thread: ARB Compressor wiring connection

Hi,
Not the cig plug, neither the socket or the fuse will be happy.

Use same guage wire (with a fuse) and Anderson plugs for a robust job.

Cheers

I've got the portable version of the ARB single (comes mounted in a box). I lopped the battery clamps off and installed an Anderson plug. This then plugs into the Anderson outlet at the back of the car. No lifting the bonnet and fiddling with the battery cover.
Makes for a quick process, and very neat and tidy. Highly recommended

Most compressors should be run from the cranking battery with the engine running because of their high ampage requirements.
If setting up a rear Anderson plug from the cranking battery to the rear of the truck then you will need some pretty solid wires and fuses to match the maximum draw of the compressor.
The cigarette lighter option isn't a good idea for the modern high volume air compressors.

This model draws ~25A at 29psi, which from what I've read online that seems to be at the lower end of the power draw scale for compressors - there are twin pump models available from online retailers drawing upwards of 90A which would indeed need a small nuclear facility to keep running.

What will you compressor draw when pumping up to 40 PSI ?
I have got one of those Thumper Dual max compressors and it can draw Up to 90A But I am pretty sure it isn't working that hard to air up to 40PSI.
It does pump 300L/min though so I suppose it is running at about 40-50A But I have absolutely No idea how to check haw many amps it is drawing when it is running.
It would be interesting to find out exactly how much amps the compressor is actually drawing when in use, Anyone know how to check this?

ARB spec for these doesn't actually provide more detail.

Just unloaded then loaded...

edit: but in this test 12-volt air compressor comparison | 4X4 Australia they show 26.2A draw at 40psi

The ARB pulls a maximum of 32A at 100psi (SOURCE). Plotting the three points we know (0, 29 and 100psi) we can roughly approximate where it might sit for 40psi - around 26A

Something like THIS should work to measure actuals

Plenty of people on here more expert than me but I would think you would be best with a clamp meter to check that.
