Anderson plug double adapter

Sorry, should have mentioned that car has isolator to stop Anderson plug when ignition off.

I had an Avan Cruisliner some years ago with a Dometic 90 litre 3 way fridge. If yours is the same fridge it will draw about 12 or 15 amps in 12V mode, from memory.

I had the same setup as you, running the fridge on 12V from the car while driving.
To make the fridge work properly and keep voltage drop within reasonable limits I had to re-cable with 6B&S from car battery to isolator and from isolator through an Anderson all the way through to the fridge. Positive and negative.

It worked as well as a 3 way on 12V can work.

Mine didn't have ESC, so I can't help you with that, sorry.

Cheers

Provided that you have the 6B&S (6AWG) cable from the start battery to the Anderson plug there should be no reason as to why you van not run both the fridge and the ESC from the same supply. Whilst the fridge does have a requirement for around 15-18 amps with minimal voltage drop the ESC only requires about 3-5 amps.

If concerned about the fridge affecting the ESC then place the ESC wiring through a 12 pin plug (using the larger pins) and its own supply from the battery.

I recommend you talk to your van supplier. In normal parlance a red anderson plug is to a unregulated source and a grey one is for an regulated source. So you need to be very careful about what source you are inputting from.

REDARC has a decent discussion here https://www.redarc.com.au/forum/discussion/44/dual-aux-batteries-and-power-sockets

As well there are usually legal requirements for the wiring of items like breakaway systems and that may include ESC as well. So I do suggest you get some specific advice from AVAN on your model

Hi Dougrham
You will also find that a red Anderson doesn’t fit into a grey one. As previously mentioned the usual convention is that the red plugs are for unregulated power and they are designed so you can’t fit one into the other. I also haven’t seen a double adapter Anderson where one is red and the other grey.

Just as electric brakes do, the ESC must be fed directly by the tow vehicles battery ( with a 30A fuse or c/b ), so you can't piggyback the 2 plugs.
Only option is to install a red anderson supplied directly from the battery.

What Gronk has said is the right way to do it. The ESC must have it's own battery supply from the main battery and use a red anderson plug.

I notice that you have both stated that the ESC MUST be supplied via a RED Anderson plug and directly from the vehicle battery, and I am curious as to where you have sourced this requirement.

I have noted that New Age and Avan do supply their ESC via a red plug, however I have also noted that Australia's largest van manufacturer supplied their ESC via the 12 pin plug.

I have also found no reference to such a requirement in the VSB1 or other Regulations. I am willing to stand corrected should such a Regulated requirement exist.

With regards to regulated or unregulated power sources, a red anderson for unregulated, so it is easily Identified, most likely linked to a solar panel which can supply a relatively small amount of power, even at short circuit.
A regulated supply, ie a vehicle battery has the ability to supply and unregulated amount of power up to it's CCA rating, usually through a set fuse size. So the idea of regulated or unregulated seems to be useless with regard to an ESC supply.

If either colour plug falls apart during use then although the brake signal may still be operating, the power to the ESC is cut. Therefore NO ESC operating. Better to have the ESC driven by an on board battery which is backed up by a decent continuous supply plug from the vehicle.
Make sure the anderson doesn't/can't come apart while driving. I have replaced a few outback for people who dragged them for many km and only the terminal ends were there, well half of the terminal pins anyway. They didn't have spares even if an ESC or brake or Power supply issue happened.

As far as regulated (controlled voltage, ie battery supply) requiring a grey plug, and unregulated (non controlled voltage, ie solar panel) requiring a red plug, the supply to the ESC is BATTERY, so is therefore a regulated supply.

I also notice that New Age have a BLUE Anderson plug for their unregulated (non voltage controlled) solar panel input to the van, where it inputs the on board solar regulator and then becomes a regulated (voltage controlled) supply before reaching the battery.

So is there any official source of information as to any requirement as to what colour Anderson plugs are used for what purpose, or is it as I suspect and believe that it is up to the person/organisation fitting/using these plugs to determine what plugs that they will use and for what purpose, solely so that they will not be mistakenly incorrectly connected.
