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
