Use of Anderson plug on compressor

G'day Allan,
That's a big claim for them.
Maybe on paper(or screen), looks really good from a sales point.
Obviously they must have tested them but that would have been brand new plugs with perfectly clean mating surfaces and new springs for max contact pressure, laboratory conditions. All down hill from the time they are fitted.
Was that a continious rating or something like a 5 second surge?
I'm betting your like me, being trained before the world of computers, something has to look like it can do the job and not just rely on a spec sheet.

Yair QC, it is a big claim. And I just quoted them without endorsing. Here's their cut-and-paste…….

"Low Resistance Silver or Tin Plated Copper Contacts
Allows UL rated currents up to 120 amps
UL Rated for Hot Plugging up to 50 Amps
Great for battery or other applications where the ability to interrupt circuits is required."

I have seen many references to "UL" over the years but know little about them. It seems to be tossed around rather like "Made in USA".

Just looking at the Anderson SB50's I would think that they may handle maybe 80 amps on a good day but 120A seems a stretch. As you say, spec sheets are useful but so is an experienced eye.
I have had total failure of an Anderson knock-off plug due to plastic housing deformation weakening the contact pressure. I am happier with the real Andersons.

Hi fellas . How many amps would you say the alligator clips supply with this compressor could handle when pumping a tyre up

Depends Nick,
I have some alligator style clamps that are rated at 600 amps for jump starting trucks so just depends on their quality, I'd choose Anderson plugs every time but have an adaptor so you can lend it to people that are too tight to buy their own......or maybe a unique type that nobody else has.

Yes jumper leads to work, but it is probably the cable which can carry 600 amps. The Alligator clamps have toothed jaws and touch in a few spots, and those spots have to be the current transfer points. OK if buried in a lead post to some degree, but clamped on brass terminal it is only point contact. Similar to the fingers in an Anderson plug. ONLY the contact actually happening is able to transfer current/energy.
Ever noticed when the jumper lead clamps are already on and the engine is started the clamp points usually give a little "burn in" to establish more contact. Sort of welding to enable the current. On the terminal there is usually small indented burn marks/craters evident after the use!

No RMD, I'm pretty sure if you read what I actually wrote and not what what you perceived I thought, the clamps were rated at 600 amps and have served me well for 4 decades. Do you think a tradesman doing heavy vehicle breakdown work would use off the shelf repco jumperleads?
Have you gone through your whole life assuming everyone is stupid? Thinking you have to explain how jumper leads work to an auto electrician with 45 plus years of experience. It's time you started thinking about what you say to who you are saying it to.

Once again qldcamper is making a clown of himself...keep it up...you deserve a medal for your rudeness and egotistical comments.

Nick said "How many amps would you say the alligator clips supply with this compressor"

I suggest he means the ones in the picture on the link for the compressor. I would not like to be using them for a sustained 90A current.

My twin chamber starts up at around 90amps then settles to around 40-50 and can alter depending on load. 5 years old and have only ever used it with the grey anderson plugs with no issues.

Some of the specs and sales blurb are scary.
90A is a huge amount of power, much more than required to compress the air. The "extra" will show as heat which is anticipated in the sales info....
................."If the unit reaches an unsafe operating temperature, a protection circuit will activate cutting off all power of the unit to prevent damage. Immediately disconnect the unit from the power source and allow it to cool if the protection circuit activates. The unit should take approximately 15 minutes to cool depending on ambient conditions."
................"+ After 5 minutes of continuous operation allow the unit to cool before restarting. Damage can
occur from continued overuse."

And this limitation....
................."Maximum Voltage: 13.8 Volt"
If you start the engine while using the compressor to run the alternator to maintain the battery capacity, the 13.8V limit at the compressor will be exceeded.

And this...
....................10.Allow the air compressor to cool completely before placing inside the carry bag. "
Which will take 15 minutes, is what they tell us.

It will be a race between overheating the compressor and flattening the battery.
I would not purchase this product.

Better off with a Boss air PX07 31.5amp draw

Malken said: ok if I wanted to use this as a power source for the van tyres, is that correct.?

Yes OK provided that the cable and fuse feeding that Anderson plug are of adequate size.

Malken.
How often would you be inflating the van tyres with no tow vehicle attached? If you use the compressor at the rear of the tow vehicle and with a reasonable length of usable lead/Cable and the hose is able to reach the front wheels, only a small increase in hose length means you have ALL tyres of the van catered for without having to delve into the van electrics. Yes you can do it if you enjoy swapping Anderson plugs!

I use an ARB compressor and an air greasegun and with the hose can grease any required points on a van as well as complete inflation.
