My fridge currently has a merrit plug connection between the fridge and the battery in the rear of my vehicle. This connection is loose and wobbly and often connection is not maintained and my fridge accidentally turns off and contents get warm.

Can I use an Anderson plug for this connection? If so, what size anderson plug? My fridge is 80L and my battery is 100ah.

Yes - as long as you make sure of the polarity +ve and -ve .

Standard 50Amp should be fine .

Hi Mandrake
Is that your fold up that you finally made.
If I may suggest but its your call.
Reverse fold them so the faces are together and it gives better protection of the working faces and they do not touch as the frame lip gives them separation.
Also when they go in a bag it adds a depth of protection before an object inadvertently in contact can do damage.

Unfortunately not my own design - just another imported product ..
To evaluate ... seems to have all the right numbers and design features - but as you point out the solar faces should be folded in for safety but the bag it comes in will hopefully be reasonably tough .

I have put a 50amp Anderson plug on the end to replace the cigarette lighter socket. I have cut the cig. socket off leaving about 150mm of cord and put an Anderson plug on the other end to make an adapter. It has come in handy on a few occasions.

Hope this helps

Cheers Luke

I have done the same thing. Only thing that I would add to every one elses comments is to add an in-line fuse.

We've got the 50 A plugs on both cars now to connect with the van, an adaptor box I made up to run smaller 12 V accessories and the compressor has one on it too so we can get power easily without the keys in the ignition.
If you use one style of plug/socket, it makes sense to stay with the same type for everything in my mind.

Alloy,
I believe your referring to the (+) and (-) cables entering into the Anderson plug itself, being colour coded is a definate advantage on all electrical connections used in 4WD's.

What I was referring to was having two Anderson plugs being connected together that did not match.
Because Andersons are a genderless design (not male/female) plug, you could get two batteries connected, or a 12v battery, solar panel etc connected to the outlet from a 240v inverter cable etc, if they were all using the identical coloured plug.
Yes I realise I've picked cables that are dangerous in the extreme but I would think it's been done previously by 'friends' who think they are doing the owner a favour at some time.

That's the great thing about Anderson Connectors. I have my 13.6 volt power supply and everything 12 volt wired with 30 amp Red/Black Anderson Powerpoles.

I can connect the fridge to the power supply.
I can connect the battery to the power supply to charge it
I can the battery to the fridge
etc

I never have to look for the right patch cable.

bet you or no-one else don't have any 12v appliances "connected to the outlet from a 240v inverter cable" ??

One would have to be INCREDIBLY STUPID to connect a 240 volt output using a plug that -

- is usually used for 12 volt
- is unsafe to use for 240 volt
- is illegal to use 240 volt

Mike,
you have to read the replies in context with my original post:
"Maîneÿ . . . posted:
Just as long as someone's child does N0T connect the wrong plug to the wrong plug when your not looking and maybe stuff something expencive :-) "

and then also my other post:
"Andersons are a genderless design (not male/female) plug, you could get two batteries connected, or a 12v battery, solar panel etc connected to the outlet from a 240v inverter cable etc, if they were all using the identical coloured plug.
Yes I realise I've picked cables that are dangerous in the extreme but I would think it's been done previously by 'friends' who think they are doing the owner a favour at some time"


Yes Mike, as you say, one would have to be INCREDIBLY STUPID to connect a 240v output to a 12v accessory.


However my point is, if all plugs ARE identical that is very, very possible :-))

While an Anderson plug is a good fix in this application its probably overkill. To me
it sounds like teh Merit plug has been damaged by poor handling as they are designed to be tight. Mine have been tight going on ten years. So a very simple fix would be to buy a new Merit plug and socket for around 10 bucks and fit them with no alterations needed.

I have had two fitted by a professional and same result both times. I have personally lost faith in the merrit plug and am going to change to an Anderson plug.

A 30 amp Anderson Powerpole is much smaller than a Merrit and is definitely not overkill.

The contacts are silver plated for a long reliable life.

Why not hard wire the lead from the fridge directly to the battery via a fuse......you have a perfectly good plug at the end of the lead going into the fridge that you can unplug if need be.

Having another connection means another chance of a fault.

Don't see why people need so many plugs and sockets for everything....maybe it's a 4x4 thing....who knows...LOL

Yep go the hard wire works perfectly, just a few dollars for another lead if you want to remove it to somewhere else.

I think its a - "just in case" thing - All of my cables are now terminated in 50Amp Andersons - including the fridge cable , 3 X 3metre extension leads 2 X Crocodile clip leads ( which make up a very long jumper lead ) Lights and battery in the trailer -- Makes sense to me to be interchangeable ..

- How many people hardwire them in ?

True but your household fridge doesn't have a another socket and plug 1m down the lead either.

Plus as you should know it is illegal to hard wire a fridge much like a in wall air conditioner or a fixed heater.

I suppose all you extension leads are 5m long and if you want 20m you join 4 of them together....perfect then you will have 4 plugs and 4 sockets.......if I was you I would look at the 3m ones....more plugs and sockets!

And if i work on your thinking everything should have a plug of some sort on it and a fridge in a vehicle should never be removed.

And another thing is a household fridge isn't put through the same vibration and environment as a portable fridge in a 4x4.

Red/Black 30 Amp Anderson Powerpoles are readily available from Jaycar shops around Australia.

You can get them much cheaper on eBay.
