Hi,
Bought a new prado, and found this at the back. anyone know what type this is? The guy said something about 'comms related anderson plug' it wont fit the common grey anderson socket.

If i know what it is, i can probably get a adapter to convert that to a normal grey socket.
thanks

You need to know exactly what they are for. As you said the different colours do not mate. The grey one is usually used for 12v power. If you connect the wrong circuits together you may end up with embarrassing smoke. They must be different colours for a reason. For instance I use grey for 12v and yellow for my solar panels unregulated power.
If you determine they are 12v you don't need an adapter, you can change the outer shell to grey.

Anderson plugs come in black, blue, yellow, red, green and grey. They will only connect to another of the same colour.
My experience is that grey is used for 12 volt and red for 24 volt although I've not seen any standard.
I use grey for 12 volt and yellow for unregulated solar connection.

'new' as in new to you or brand new?
brand new, take it to the dealer.
2nd hand, first put a multimeter on them to establish if they are live and which is +ve or -ve.
probably need to find out where the cable goes and if it's fused etc.
no adapter needed, re-terminate the cables onto an anderson plug if required.

First step would have to be to trace the cables back to see where they go and what they're used for. Are they 12v ?
From there you can decide the next step.

They look to be the Anderson PowerPole fitting.

Do they have fuses anywhere? Maybe back near the battery. If so the what sizes.

You don't have to cut the connectors off, just swap the cover for a normal grey one. Make sure you disconnect it for the battery first though. Use a small screw driver in the end to pust the spring clip down and the connector will pull out of the shell. Simply clip into the new shell.

Hi TomH, I have used the Red Blue lots of times at work and have never seen the top type connector. But yeah, check that it have the normal type connectors shown in the bottom photo.

We used to use the blue and the red plugs in Telstra solar installations at towers and radio sites. Reckon 20 amps max. The grey are 50 amp.

Certainly not the accepted grey Anderson plug that everyone uses.

Cut them off and buy a grey one and either crimp or solder the cables in

Before you cut anything.

Chase the wires up as already suggested and see what they are about. They may be two independent circuits and may be very helpful.

These are Anderson plugs called Power Pole connectors. They are rated at 30 amps so should be sufficient for most applications such as fridges or low power inverters. Jaycar sell then so if you want to use the existing cable get the mating connectors there for what you want to power. I'd use them rather than cut them off and replace with the single Anderson plug.

The advantage of replacing the red/blue PowerPoles with a 50amp grey is that whatever mates to it can be used in more setups having a grey connector.

Maybe all the previous owner needed were two positives and colour coded them according to which circuit each was for and thus was fused correctly for that purpose.

Not everyone wants to use 50 amp Anderson plugs for a 10 amp circuit for a fridge or even a 1 amp circuit for the external camp lighting.

I have read that the red Anderson sockets are often used to provide a dedicated 12V to the Al-ko ESC system.
Perhaps that it what is was for!

Comms related? Perhaps they supply 30 Amps to an HF radio.

Those power pole plugs have been around for a long time - I used them with DC stuff about 25 years ago. They were versatile because they are single plugs, both sides are shielded, they interlock so you can make up a series of 1,2,3,4 or whatever, and when you interlock them, you create a screw hole so they can be surface mounted.

But they were a bit bulky and got replaced by many other connectors that could carry more current and were twin. The common grey anderson plug has become so widely available and incredibly cheap that it is what you see most people using for many RV applications, and I'd also give the power pole the chop and just use whatever suits your needs.

There are lots of references to grey Anderson plugs on this forum.

I am not sure why but lots of people think they are 50A. maybe the 50 in the product number.

The Grey Anderson plugs are rated at 120A.

Anderson seem to think so.

Obviously copies are not rated the same as the originals.

I dunno Tom. I'm just quoting the manufacturers specifications for their products.

If you don't agree, why don't you take it up with them.

Anderson rate the sb50 at 50a continuous in any of seven colours one of which is grey.
The also make sb120 rated at 120a in three colours including grey.
Also sb175 and sb350 at 350a in grey,red,blue. Each connector will only mate with same colour and rating

Ian, that shop is not Anderson Power inc. They do not make the connectors. That website just uses the Anderson name to fool people, including you. They are just a little old shop in Dandenong trading on the Anderson name - Sabtec. Pty ltd

The manufacturers website is below. It clearly rates the SB50 at 120A
From their website.

THE REAL MANUFACTURER'S WEBSITE

SB®50 - UP TO 120 AMPS
That is any colour, The SB 175 is rated at 240A, the SB 175 is rated at 280A and the SB340 is rated at 450A

Those ratings are based on UL standard 1977. Go read it.

Do you believe the manufacturer or a small shop in Dandenong that fools you with it's name?

Sneaky bastards. Not the first time someone used a famous name to promote own adgenda.
I checked out anderson us ,ratings they give csa rating is 50A for connecting, disconnecting, and carrying; and the ul 1977 120A rating for carrying current.As most people would connect and disconnect with load off the 120A would suit.

These are Anderson Power Pole connectors. Most likely the PP15-45 size. These are different to the Anderson "SB 50 series" connectors that we know as the grey 50 Amp connectors and do not mate with each other. Anderson make a large range of connectors. These two are the most commonl styles seen in the camping world in Australia

The Power Pole connectors come in 4 different sizes and several colours. The PP15-45 is the smallest. There are different size pins/contacts available to take different gauge wire for each size connector. In all cases, the actual contact dimension is the same for the pins that match the connector, just the hole size to accept different gauge wire varies.
As these are designed to be crimped, the different size pins give best crimping to different size wires. These connectors are rated up to 45 amps.

The same concepts are also applied to the SB series connectors. There are also 4 sizes and come in different colours. The ones we know of are the smallest size housing in the series (other sizes go up to 600 amps!) Unlike the Power Pole connectors, there are supple mechanical difference in the SB series (even though they look identical) that prevent the different colours mating with each other. Like the Power Pole connectors they also have different pins to take different gauge wire.

The Americans being Americans seem to have adopted the practice of calling the different size contacts by the current the wire intended for that pin is able to carry.
Hence the 50 amp connector is a standard SB50 housing with a contact with the largest hole size contact available, but contacts with smaller holes to reliably crimp smaller gauge wire are available.
We would most likely call the contacts 13mm, 6mm or 5.3mm contacts.
This size housing is rated up to 120 amps with appropriate contacts.

As to the OP, I would suggest tracing back the wires to see where they are sourced from and making a decision as to what to do from there. They may be 2 x 12v sources, each fused differently, or one switched by the ignition, one permanent power or maybe the blue is actually an earth because the installer had no black wire(???). Only tracing will tell.
The OP can then decide to buy Power Pole connectors to use the existing, or re-terminate in a connector of his choice.

I use the Power Pole connectors a lot due to their small size. They can carry all the current I need for everything around my camper and car without the bulk of the SB connectors. Where a physically more rugged connection is required (ie on the bumper supplying battery power to the trailer ), the SB50 is used.

Goggle "Anderson Power Products" for info and purchase sources.
