25A 12V Power connector

Anyone know of an easily available 25A 12V power connector that won't cost me an arm and a leg.

Doesn't need to be waterproof, splashproof would be useful, but could make do with it not being.

Nasher.

For my Land Rover roof mounted spot lights I used a rubber covered 2 pin connector and socket as used on strimmers and lawn mowers etc. Don't know the rating at 12v but pretty big brass pins.

My lamps are 100w each x4 = about 33 amps and it's lasted fine - packed it with silicone grease and no sign of corrosion either!!!

B+Q used to sell them.

Oh about 3 - cheap enough?

Thanks mate, good call.

It's to create a plug and socket in the console for the 12V pump I have to inflate the smaller Nashers SIB.

It works really well, but I have to unstrap one of the battery boxes and use the large croc clips attached to the pump on the battery terminals.

Thinking about it, I may use a std Euro(PC power) type plug and socket, then I can attach the croc clips to a short length of cable with a socket on the end so I can still use the croc clips on the car battery to blow up the camp beds.

Believe Euro Plugs and sockets are rated at 10A for 240V, so should be OK for 25A at 12V. - Que somebody to explain why not

It's going to see intermittent use, so I wouldn't be too concerned about going over the contacts' ratings.

If it were me, I would connect it and try it, and see if you get a significant temp rise at the contacts. If it's higher than what you get in the wires themselves, another option may be desirable. If not, then I would say it's fine.

take a look at the earth pin, its probably bigger and can carry more current than the live and neutral pin. maybe you could parallel connect the live and neutral as one pin to carry double the rating, ie 20 amps,
and use the bigger earth pin as the other pole? just an idea.
the other thing which may be of use is the small golf buggy battery connectors, I only have 200 amp ones of forklifts but invalid carrages and golf buggys use smaller ones.

Have a look at Anderson connectors;

A lot of recovery companies use them for jump leads

Thanks guys

Jono, I've used Vehicle Wiring products loads of times before when I was building bikes and had forgotten about them.

I'm no electrician, but isn't the voltage irrelevant for the type of connector? It's surely the ampage which dictates the flow and, therefore, the heat generated. Obviously, the ampage will alter depending on the equipment being used and the voltage supply but is it not the case that if a connector is rated for 25A it will power equipment of 6000W at 240V, or 300W at 12V?
